Cannot find module './src/common' only in npm version 2

[ZeroCho]

I recently changed npm version from 3 to 2 in order to use google app engine.
I could successfully install packages when i was using npm3, but after i changed to npm2, this error happens. I don't use this package directly. It is installed via dependencies of postcss-cssnext.

I think it's related to the way npm installs packages. I heard that npm3 differently installs its packages than npm2.

    throw err;

and the strange thing is, after failing npm install, I tried to run that command again, then it succeeded. First install always fails and second install succeeds.

@MoOx i have above error with caniuse-api which is a dependency of postcss-cssnext. I found many issues related to caniuse-api in postcss-cssnext repository. Do you think is this one of them?

There is no such file as src/common. The issue seems to be a shelljs issue.

@MoOx Thank you! I'll make an issue at that repository

Sorry the this message doesn't help at all. Nothing is interesting here...
