I relatively new to coding so I am not (yet) running virtual environments. Rather, I am just downloading packages with pip straight to my pc to run python 3.7 in atom.

When I tried to use pip the other day to install the scrapy package like so -m pip install --user scrapy

I got this error: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'c:\\users\\adrian\\appdata\\roaming\\python\\python37\\site-packages\\pip-19.0.1.dist-info\\METADATA'

Most of the other answers I have seen on related errors had people use conda to install some type of fix I think? When I tried to use conda to execute one of the fixes I recieved a CondaHTTPError: SSLError(MaxRetryError('HTTPSConnectionPool(host=\'repo.anaconda.com\', port=443): Max retries exceeded with url: /pkgs/free/noarch/repodata.json.bz2 (Caused by SSLError("Can\'t connect to HTTPS URL because the SSL module is not available.

Any direction would be heartily appreciated :-)

TL;DR:

Problem: Long install path

Solution 1: Install the desired python package (in my case tensorflow) in the folder which has a shorter path (for example C:/my_py_packages/some_package)

Solution 2: Set the registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem@LongPathsEnabled to 1 as mentioned here.



Original answer: I got here by having this kind of error when I tried installing tensorflow library. My error was the following:

Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'c:\moj ifajlovi\faks\11master\1semestar\siap-sistemizaistrazivanjeianalizupodataka_(datamining)\projek at\rad\venvs\siap_venv\Lib\site-packages\tensorflow_estimator\python\estimator\canned\line ar_optimizer\python\utils\pycache\sharded_mutable_dense_hashtable.cpython-37.pyc'

So, there was no sharded_mutable_dense_hashtable.cpython-37.pyc file in the __pycache__ directory. But, sharded_mutable_dense_hashtable.cpython-37.pyc file was in the utils directory (which is the parent directory of __pycache__ directory).

That's why I tried manually copying the sharded_mutable_dense_hashtable.cpython-37.pyc file in the __pycache__ directory. When I tried that, I had a copy error which stated that the path was too long, so it couldn't put the file in the directory.

So, the solution:

Install the desired python package (in my case tensorflow) in the folder which has a shorter path (for example C:/my_py_packages/some_package) or set the registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem@LongPathsEnabled to 1 as mentioned here.

    As another option you could enable support of long file names in Windows 10 by changing HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled registry value. – Dmitry Sobolev Jul 02 '19 at 05:05

    The same error message can bite you when you pip install pytorch after getting python from Microsoft Store. +1 since your post got me onto the root cause "path too long", see https://www.reddit.com/r/pytorch/comments/c6cllq/issue_installing_pytorch/ – Jonas Heidelberg Aug 05 '19 at 22:05
  • @DmitrySobolev Thank you for the easy and useful option. I am using Windows 7 and I just checked and didn't find the LongPathsEnabled registry in FileSystem registry folder. – Filip Savic Aug 06 '19 at 23:11

    I'd put the regedit solution as a tl;dr right at the start of the answer. I've almost skipped it here, and it's the right answer. – Elazar Nov 25 '19 at 08:27

    @Elazar - I added a TL;DR. – Filip Savic Nov 26 '19 at 09:23
  • second solution worked for me. run the registry as administrator if needed – Valentin Mar 20 '21 at 12:00

    in order to install the package in another loaction, you can use --target flag, e.g: pip3 install --upgrade --target="C:\Users\\" if you get an error: "ERROR: Can not combine '--user' and '--target'" you can add "--no-user" flag at the end – Amitay Drummer Jul 14 '21 at 12:23
  • This can be done by running `Set-ItemProperty -Path "HKLM:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem" -Name "LongPathsEnabled" -Value 1` – Jesper Hustad Oct 22 '21 at 11:58

This is what I did:

I could not install my python package due to this error ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'c:\\users\\banipreet\\anaconda3\\envs\\env-gpu\\lib\\site-packages\\requests-2.24.0.dist-info\\METADATA'

I simply removed this folder 'c:\\users\\banipreet\\anaconda3\\envs\\env-gpu\\lib\\site-packages\\requests-2.24.0.dist-info and retried pip install my-package, and it installed the package sucessfully.

    LongPathsEnabled didn't work for me, but this did. Thanks – Taher Apr 05 '21 at 10:01

    LongPathsEnabled didn't work for me as well. I was able to install packages using 'conda install -c conda-forge ' still there were some packages for which I needed pip to get them installed. You saved my day, nothing worked but this worked for me. Huge thanks! – ANKIT MORAL May 13 '21 at 15:53

    Nothing worked for me but this solution. I wasted a few hours trying to solve it, can't believe the solution is so simple. – Lior Magen Jun 10 '21 at 13:15
  • Longpathsenabled didn't work but this solution did work, even though some packages had dependency conflicts. – Mahlatse Sep 16 '21 at 13:02

Remove the 260 Character Path Limit by Editing the Registry, change LongPathsEnabled to 1, the regedit path in: 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem

enter image description here

finally: restart your computer, or logout!

First To Access The System Registry:

  1. Click Start, and then click Run.
  2. In the Open box, paste %systemroot%\syswow64\regedit , and then click OK.

Then do the following below as mentioned by Filip Savic and dayudodo:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem@LongPathsEnabled to 1

I had the same error trying to install Jupyter, with the path under my user profile ending with \site-packages\pip-19.0.1.dist-info\METADATA

When I checked that location it didnt contain METADATA, but another folder named pip-19.0.1.dist-info That folder had several files in it including METADATA

I moved those files back the directory so it matched the path listed in the error and then upgraded pip (Under an administrator account)

pip3 install --upgrade pip

Which worked and updated pip

I could then run the Jupyter install and got no error

I experienced this error while I was installing Apache Superset on Windows 10. The problem is with the MAX_PATH length.

pip on windows is not able to handle those long installation path url so it usually results in errors.

Solution: What worked for me was to Uninstall python then ReInstalled it again but this time after a successful reinstallation, you HAVE TO DISABLE THE PATH LENGTH LIMIT

Like on the highlighted region there.

So the above so called solution didn't make much sense to me.. Sorter path?? Anyways, what worked for me, is this.

My error: 

Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'c:\\users\\MYUSERNAME\\appdata\\roaming\\python\\python37\\site-packages\\pip-19.0.1.dist-info\\METADATA'

So I went to the directory: 

c:\\users\\MYUSERNAME\\appdata\\roaming\\python\\python37\\site-packages\\pip-19.0.1.dist-info\\

Indeed there was no MetaData file. However there was a folder called 19.0.1.dist-info, inside that, has the meta data file. Just move it outside into the above directory, and BAM! Problem fixed.

  • Copying the METADATA file from my pipxxx.dist-info folder into the requests-xx folder worked for me (After changing the max_path as suggested elsewhere which didn't work) – Wyse09 Feb 12 '22 at 03:36

Just ran into a similar problem with but with different versions. Similar to what EsCS69 said I just found the director and saw that there was no MetaData file. However I couldn't just pull it out from another file. So instead I justed deleted that folder and ran pip install --upgrade --force-reinstall tensorflow-gpuor pip install --upgrade --force-reinstall tensorflow if you aren't using the gpu version. Problem solved.

The file path is to long, open a PowerShell prompt as an administrator and run:

Set-ItemProperty -Path "HKLM:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem" -Name "LongPathsEnabled" -Value 1

You might not like this answer, but what worked for me was to find the file: "METADATA" from a folder with an older version and copy it into the newer one. This is not a solution I'm confident in, but pip at least finished installing.

Try deleting the package in envs/$env_name/Lib/site-packages

I ended up deleting the whole directory and re-running "pip install ..." and that worked for me.

Changing the Long install path value to 1 did NOT solve problem in my case. I have removed the local folder which is giving an error and installed the package again and it worked.

Following is the error I have seen: :ERROR: Could not install packages due to an OSError: [Errno 2] No such file or directory: 'c:\users\user_name\appdata\local\continuum\anaconda3\lib\site-packages\numpy-1.20.1.dist-info\METADATA'

I removed the folder: "'c:\users\user_name\appdata\local\continuum\anaconda3\lib\site-packages\numpy-1.20.1.dist-info'

For me what worked is running the same command 3 times. Don't know why, but it solved the issue.

First time enter image description here

Second Time enter image description here

Third time's a charm :) enter image description here

I had this problem while trying to install pytest on macOS

ERROR: Could not install packages due to an OSError: [Errno 2] No such file or directory: '/Users/<USERNAME>/Projects/venvs/<VIRTUALENV_NAME>/lib/python3.8/site-packages/pytest-6.2.5.dist-info/METADATA

I navigated to the site-packages directory and deleted pytest-6.2.5.dist-info folder. Then try running the package installation command again.

Windows 10

Windows limits locations paths with more than 260 characters. You should just enable that following this 4 steps!!!

  1. Click Window key and type gpedit. msc, then press the Enter key.
  2. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > System > Filesystem.
  3. Double click Enable NTFS long paths.
  4. Select Enabled, then click OK.

Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'c:\\users\\adrian\\appdata\\roaming\\python\\python37\\site-packages\\pip-19.0.1.dist-info\\METADATA' . what we need to do is delete that folder , in this case pip-19.0.1.dist-info ;

Problem solved

A simple pip upgrade did the trick for me.
