PHP Warning: proc_open(): posix_spawn() failed: No such file or directory

[g105b]

This error message was confusing me while working on an older project.

It turns out, the problem was that I hadn't performed npm install, and a file wasn't present that was expected to run.

I think this error message is incredibly confusing. If this error message appears, is it always because the dependent binary/script isn't available? If so, the error message should be worded accordingly:

Error: The required command can not be found (./node_modules/.bin/something)
