npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Likely cause: https://github.com/andreypopp/esy-solve-cudf/blob/d293f2116def0b0b02eef487158ae440d21cc8db/postinstall.js#L17

I would volunteer to fix it, but without a working esy install, that would be rather difficult to test the fix.

Package.json None yet.

Actual behavior: See above.

Expected behavior: npm is able to globally install esy easily.

Additional steps to reproduce:

1. On a fresh instance of Ubuntu 20.04:

$ sudo apt install npm
$ sudo npm install -g npm
[...]
$ sudo npm install -g esy@latest

[andreypopp]

Try sudo npm install -g --unsafe-perm esy Invocation. The unsafe-perm flag is needed when installing with sudo.

[wesleybits]

That just fetches the bundle, and seems to do no build. I don't see the usual artifacts in /usr/local/lib/npm_packages/esy/, and the paths where the usual distribution artifacts would be post-build are missing.

Are we certain that the line I linked from esy's dependency solver isn't the culprit (a decimal number where something in octal seems to be implied)? I would submit a fix, but without esy, I have no means to test it.

@wesleybits Could you try to install it in a different prefix (something like ~/.npm) with npm i -g esy --prefix ~/.npm (assumming you have permissions at ~/.npm)

[AkechiShiro]

@ManasJayanth I can confirm that the install using the prefix option works fine, given that permission are well defined for the prefix folder ~/.npm.

Thanks! We'll working on improving the error message.

I ran into this error when trying to run npm install -g esy (no sudo) inside of a Vercel deploy. Most likely, Vercel is using amazon linux docker image.
