There is another wired thing about npm. When I try to install gulp globally I get:

Error: could not get uid/gid
net.js:135
    this._handle.open(options.fd);
                 ^

Same here. In fact if I try to update npm update -g npm@latest it attempts to copy lodash to the staging directory then throws the errror. Following this subsequent attempts to use npm are broken because it can no longer find lodash.

IMPORTANT

This really should be of utmost importance to the team. I for one was very excited and love how everything else works, but as you are adding this feature to windows with the intention of bringing web developers back to windows this needs fixing ASAP. This alone will stop me switching back to windows for web development and I'm sure it will be the same for many. It defeats the purpose of switching for me. Please please please fix.

@borovaka you can fix that error by allowing unsafe perms

npm config set unsafe-perm=true

Already tried. It bypasses the error but it still doesn't work. You will
get a permissions access error still or at least I did.

@jamesscholeyweb right, I was able to get to your error after setting those perms. Otherwise I wasn't able to do anything.

This seems to be the underlying issue.

It seems to be an issue with symlinks

Confirmed - this is totally related to the symlink issue.

Same here with

npm install typescript

This looks a lot like #3. We can keep the conversation going on there.

What I can say right now is that things are getting better (at least in non-mnt directories.). On my dev box I see:

russ@RUSSALEX-DESK:~/tmp$ npm list
/home/russ/tmp
├── acorn@3.0.4
├─┬ gulp@3.9.1
│ ├── archy@1.0.0
│ ├─┬ chalk@1.1.3

It goes on from there. I should point out that I have not tried to actually use any of these, I have only installed them.

The team is hard at work getting stuff up and running. Npm is one of those things we're looking at now.

Full disclosure here. Doing a little more testing on our internal build and finding that doing an "npm -g install " still throws the uv_pipe_open error, even when in ~/tmp.

We have someone looking into it.

If you're using VS Code and find yourself getting this error message, close VS Code, run the desired command, and restart VS Code, as indicated in https://stackoverflow.com/questions/60853873/eaccess-error-when-installing-packages-on-wsl

If you installed node from apt-get, uninstall it completely and install it from NVM (Node Version Manager)

Uninstalling node (Ubuntu)

sudo apt-get purge --auto-remove nodejs

Update apt indexes

sudo apt update && sudo apt upgrade

Install NVM

sudo apt-get install -y curl \
&& curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash \
&& source ~/.bashrc

Finally, install node and npm

nvm install --lts

@borovaka you can fix that error by allowing unsafe perms

npm config set unsafe-perm=true

it says:

npm ERR! `unsafe-perm` is not a valid npm option

npm ERR! A complete log of this run can be found in:

Thanks it worked

I have fixed my problem on mac by
sudo chown -R 501:20 "/Users/<my_username>/.npm"
