unix - How add commands to cygwin - npm

Question

I use cygwin on windows 8.1 to have an Unix shell. But I cannot run commands such as npm from it.

What should I do to do it? Add some kind of env var to cygwin? Why it doesn't use windows PATH?

Edit: Actually I think that I misunderstood the problem here. It looks like npm is found by cygwin but it cannot be used. For instance I can use git from cygwin without any trouble.

$ npm
/cygdrive/d/Logiciels installés/nodejs/npm: line 2: $'
' : command not found
/cygdrive/d/Logiciels installés/nodejs/npm: line 4: $'
' : command not found
/cygdrive/d/Logiciels installés/nodejs/npm: line 5: Syntax error around ? $'in
' ?
'cygdrive/d/Logiciels installés/nodejs/npm: line 5: `case `uname` in

So, it looks actually more like a npm issue.

This seems to be a problem with the npm script as mentioned here, https://github.com/joyent/node/issues/5912

Assuming you have installed nodejs in the default location you can run the following dos2unix command and fix the error.

dos2unix c:/Program Files/nodejs/npm

This fixed my problems with the npm script.
