Re: How to work with npm from guix shell

[Roland Everaert]

Hello,

Removing the '-g' option allows me to go further, however, I encounter some 
dependency problems.

I will get in touch with the project maintainer to get more help.

BTW, is there any articles that go in depth with the use of guix shell?

I have still difficulties to get en environment right and to understand all the 
subtelties of the available options for the command.

Thanks for the help,

Roland Everaert

The -g flag tells npm that you want to install the package globaly, 
which on guix, is inside the read-only gnu store.
You can either just omit -g to install the packages in the current 
directory, or use 
, 
which was proposed here:

Guix packages packages from other language specific packagers, like pip. 
But I don't think we have node modules tracked by guix.

AFAIK, the above solution is best practice.

Someone else might know more.

This command installs stuff globally, which tries to access system's 
directories and that's what's giving you the error (the store is immutable).
What I suggest is to remove the -g so the packages are going to be installed in 
the current folder under node_modules, and you'll be able to run them by their 
path:

./node_modules/community-server/bin/whatever

You can also add that to the PATH and simplify some things.
That's what I do.

But there might be other better options, like setting where should npm install 
the packages globally? I don't know about that.

Hope that helps

I am running the application in a guix shell session for testing purposes.
