[Pkg-javascript-devel] Bug#930034: please help us pinpoint the issue

[Paolo Greppi]

Hi Hubert,

One cause for the issue you are having could be globally installed (or otherwise reachable via your module search path) node modules that conflict with those in our packaged yarnpkg.

Is NODE_PATH set ?

If you try:
   npm root -g
it should return /usr/local/lib/node_modules
And:
   ls -l /usr/local/lib/node_modules
should be empty.

Besides these checks, to help us pinpoint the problem, can you please try to repeat the procedure with debug information turned on for all modules like this:
   NODE_DEBUG=* yarnpkg add leftpad &> log
and attach the log to this bug.

Another option would be to debug the JS execution with chromium inspector:
https://nodejs.org/en/docs/guides/debugging-getting-started/
launching yarnpkg lile this:
   node --inspect /usr/bin/yarnpkg ...
and look for what code it is executing when it encounters the EINVAL error.

Let us know !

Paolo
