NVM / Node installation. Command not recognised

Time:02-15

Ubuntu Linux 20.04.

Setting up a new machine I installed the lastest version of npm. At the time that was v17.4.0. For some reason it also has folders for v17.3.0 in /home/dougi/.nvm/versions/node.

I then found I needed the LTS version for certain things and so used nvm to install v16.13.2.

I uninstalled v17.4.0 with nvm uninstall v17.4.0 which removed all traces of v17.4.0, but left the folders for v17.3.0 (no idea why they are there).

Today I installed ionic cli with npm install -g @ionic/cli and it puts the ionic files in /home/dougi/.nvm/versions/node/v17.3.0/bin. When I run ionic start I get Command 'ionic' not found.... Using nvm ls I can see that I am currently using v16.13.2, so I'm unsure why ionic is being installed to the v17.3.0 folder. I assume that this is why the ionic command is not recognised. Output from nvm ls is:

enter image description here

I also note a lot of red, which may be bad?

What I am doing wrong please?

How do I get rid of the v17.3.0 folders (I assume not good to just delete them)?

How do I get ionic to install and be recognised under node v16.13.2?

Thanks!

Try to delete that manually using:

cd ~/.nvm/versions/node
sudo rm -rf v17.4.0/

and also make sure that you are actually switched to the 16 version:

nvm install 16
nvm use 16
nvm alias default 16

CodePudding user response:

When running nvm to manage node you don't want to use the global prefix in npm as nvm needs to manage that.

I had a global npm prefix set and so all npm installations going to the path of the node version in the npm prefix.

You can check your npm global prefix with:

npm root -g

Deleting that prefix then enables nvm to decide which node version to install into. To delete the global npm prefix:

npm config delete prefix

nvm now worked properly and when I ran npm install -g @ionic/cli it properly installed to the version of node currently selected in nvm. Phew!

Thank you to @sina.ce for his help in getting me there!
