Volta: Can't install packages with npm@7 and Volta 0.9

[DirtyF]

Hi,

I just upgraded to the latest 0.9 and I can't install packages anymore 😞

volta install netlify-cli
error: Could not install package 'netlify-cli'

Please confirm the package is valid and run with `--verbose` for more diagnostics.

I get the same error when i run npm install --global.

It was working perfectly before, is there some node/npm config to check here?

which node
/Users/frank/.volta/bin/node

Thanks

Same thing here!

Can you try with:

VOLTA_LOGLEVEL=debug RUST_BACKTRACE=full volta install <thing>

And share the output?

[DirtyF]

Sure.

volta install npm@7
success: installed and set [email protected] as default

volta install yarn
success: installed and set [email protected] as default

Does this only happen with npm@7 set as your default, or is it the same even with npm@6?

[DirtyF]

Bingo, it looks like so:

volta install tailwindcss
success: installed [email protected] with executables: tailwind, tailwindcss

volta install npm@7
success: installed and set [email protected] as default

volta install tailwindcss
error: Could not install package 'tailwindcss'

I _think_ I could install npm packages with npm@7 with previous Volta version 🤔

Thanks for the report @DirtyF and the debugging @rwjblue! It looks like this is a bug with custom prefix directories in npm 7, see https://github.com/npm/cli/issues/2012.

That said, we can probably work around it in Volta by making sure those directories are created ahead of time.

[DirtyF]

Switched back to npm@6 for now, and I'm back in business 😄
Thanks for your help @rwjblue 🙏

Closing since this is an upstream issue with npm@7. 😌

[charlespierce]

I'm actually going to keep this open for now, as while it's an upstream bug, we can still work around it and make our implementation more robust.

Released the fix for this in Volta 0.9.1
