npm install gets stuck at fetchMetadata

Question

I\'m currently unable to run npm install in any project since today. I\'m running node v8.2.1 & npm 5.3.0 (installed via nvm).

When typing npm

Answer 1

Probably not the best solution, but my workaround was to push up my active branches to origin, re-clone my repo into a different folder, then npm install in the new folder.

Answer 2

You can try by setting the configuration to:

 npm config set registry

It works for me

Answer 3

I have experienced this and fixed it with rm -rf ~/.npm or npm cache clean.

If that doesn't work, perhaps install with Homebrew instead of nvm, to eliminate some possibilities.

Answer 4

Adding to @CptUnlucky's answer.

npm config set registry "http://registry.npmjs.org"

This forces the http fetch. If this alone doesn't work, throttle the number of simultaneous connections that can be established. Default Max connections is 50.

npm set maxsockets 3

That worked for me.

Answer 5

I solve this issue by opening the package-lock.json and reset all the json. Delete the current content and replace it with

{}

then reinstall the package.

Answer 6

This is how I resolved this after spending half an hour:

1. npm config set registry http://registry.npmjs.org/ --global
2. npm cache clear --force
3. setting package-lock.json to {} only
4. npm install --verbose

node: v12.14.1 npm: v6.13.4

This issue occure when I tried running ng update on angular 6 app to update it to angular 9.
