I updated Node.js to 5.x, and after then I can't use npm install. Every time to use this, it causes errors:

and npm install not working anymore, I can't go back to previous version of node!

$ sudo -i
# npm install -g n    // causes same errors!
# n 4.4.2;            // not working anymore.

Should I reinstall node.js entirely? Or can I fix it? Any advice will very appreciate.

  • I got following error when I try to install a package. The problem was in my package.json file and somehow it's edited one installed package name to empty string. No new package was not installing until I fixed the package.json file. npm ERR! code EINVALIDTYPE npm ERR! typeerror Error: Argument #2: Expected string but got null npm ERR! typeerror at exports.findRequirement (C:\Program Files\nodejs\node_modules\npm\lib\install\deps.js:756:3) npm ERR! typeerror at computeMetadata (C:\Program Files\nodejs\node_modules\npm\lib\install\deps.js:135:9) npm ERR! typeerror

Reset to default

Try to clean your npm cache at first:

rm -rf ~/.npm

npm cache clear

Next step you could try to rebuild your existing packages:

npm rebuild

Also guys say, that Node version 5.1 could fix this issue:

After putting Node 5, npm ERR! code EINVALIDTYPE?
