I am using Ubuntu Linux.

How can I check current nodejs version? I guess, I have 6 version, but I am not sure.

And is there way to change it, because I need 4 version. Can some one give step by step commands?

  • You can use NVM (Node version management) to manage multiple active node.js versions. https://github.com/creationix/nvm – Andan H M Aug 11 '17 at 10:11

Open up the terminal and type node -v

To change your node version, I'd recommend installing nvm. Once installed, to switch versions it's as simple as

nvm use <version>

You can check your current NodeJS version by using command node -v. And changing your version can be done by using node version manager. The easiest way to do that is by running this $ npm install -g n now you can change your current NodeJS version using n (version) e.g. n 4.0.0. 

node -v
npm install -g n
n 4.0.0

    This does not change the active version. How do I change to the stable version, for instance. I tried:
    # n latest
    installing : node-v15.7.0
    mkdir : /usr/local/n/versions/node/15.7.0
    fetch : https://nodejs.org/dist/v15.7.0/node-v15.7.0-linux-x64.tar.xz
    installed : v15.7.0 to /usr/local/bin/node
    active : v10.13.0 at /opt/conda/bin/node
    # n stable
    installed : v14.15.4 to /usr/local/bin/node
    active : v10.13.0 at /opt/conda/bin/node

  • Yes, this is annoying, what I ended up doing was removing node (https://askubuntu.com/questions/786015/how-to-remove-nodejs-from-ubuntu-16-04) and then you can either symlink /usr/local/bin/[node~npm] into /usr/bin or you can add /usr/local/bin to your path. – satnhak Feb 25 '21 at 21:29

You can check your version by using this code (node -v) in linux terminal and If you want to upgrade it to stable version you can use following codes one by one.

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

Just type npm version in your command line and it will display all the version details about node, npm, v8 engine etc.
