在 Ubuntu 上更新 Node.js - 更新后版本未更改

Question

I'm trying to update Node.js on Ubuntu by commands:

sudo npm install -g n
sudo n latest

I got response:

installed : v16.6.1 (with npm 7.20.3)

But when I'm checking the version by node -v or nodejs -v I'm getting:

v10.19.0

Is it required to manually change the system paths? Old version is not replaced?

Answer 1

the reason is that the path for the new node is not included in $PATH .

you can check that by running which node , it will print the path to node cli.

you can fix it by including the path which n install node to the system PATH

Answer 2

I had the same problem with my Ubuntu 21.10, and I was able to fix it and get the correct version of nodejs to show in my terminal.

The solution is to Set 16.6.1 (or another version) as default

 nvm alias default 16.6.1

Answer 3

Try this

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

Upgrade to the latest version, you can use

$ sudo n latest

Fix PATH:

$ sudo apt-get install --reinstall nodejs-legacy
