nvm is not compatible with the npm config “prefix” option:

Question

I am trying to run another NodeJS version with nvm but getting this error:

$ nvm use v4.2.4

nvm is not compatible with the npm config \"prefix\         


        

Answer 1

I solved this problem when it was showing on VSCode and JetBrains Terminals, but not in the native terminal using the following commands:

ls -la /usr/local/bin | grep "np[mx]"

This will give you the resolved path at the end:

... npm -> ../lib/node_modules/npm/bin/npm-cli.js
... npx -> ../lib/node_modules/npm/bin/npx-cli.js

From there, removing the files and relaunching VS Code should fix the issue:

rm -R /usr/local/bin/npm /usr/local/lib/node_modules/npm/bin/npm-cli.js
rm -R /usr/local/bin/npx /usr/local/lib/node_modules/npm/bin/npx-cli.js
