Unable to run gulp

[blindbox]

Do you want to request a feature or report a bug?
A bug. Issue #927 might be related.

What is the current behavior?
Installing gulp-cli using yarn global add gulp-cli leads to the following error when running gulp

C:\Windows\System32>cmd.exe /C gulp
C:\Windows\System32>"$basedir/C:/Users/user/AppData/Local/Yarn/config/global/node_modules/.bin/gulp.cmd"   "$@"
The filename, directory name, or volume label syntax is incorrect.

C:\Windows\System32>exit $?

Alternatively, if ran through a git bash, I'll instead get this error:

user@user-PC MINGW64 ~
$ gulp
/bin/sh: /d/Program Files/nodejs/C:/Users/user/AppData/Local/Yarn/config/global/node_modules/.bin/gulp: No such file or directory

user@user-PC MINGW64 ~
$

If the current behavior is a bug, please provide the steps to reproduce.

• Install gulp-cli globally using yarn global add gulp-cli
• Run gulp through Git Bash or cmd.exe

What is the expected behavior?
Gulp should run without any errors.

Please mention your node.js, yarn and operating system version.
node: v6.9.4
yarn: 0.18.1
OS: Windows 7 64-bit Ultimate.

@blindbox are you able to run any other program installed using yarn global add?

[blindbox]

Nope. Here's one with maildev.

C:\Windows\System32>"$basedir/C:/Users/user/AppData/Local/Yarn/config/global/node_modules/.bin/maildev.cmd"   "$@"
The filename, directory name, or volume label syntax is incorrect.

C:\Windows\System32>exit $?

My nodejs install is in F drive, and so is my yarn install.

I was thinking it might be related to nodejs being installed in a different drive. So, with both NodeJS and Yarn installed to drive C, here's what I get:

Using command prompt

C:\Windows\System32>"$basedir/../../Users/user/AppData/Local/Yarn/config/global/node_modules/.bin/maildev.cmd"   "$@"
The system cannot find the path specified.

C:\Windows\System32>exit $?

Using git bash (it works!)

$ maildev --version
0.14.0

I think the files generated by yarn can be quite interesting. Here's one when I installed yarn and nodejs on drive C (there's two files):

"$basedir/../../Users/user/AppData/Local/Yarn/config/global/node_modules/.bin/maildev.cmd"   "$@"
exit $?

File maildev.cmd.cmd found in the nodejs exe directory

@"%~dp0\..\..\Users\user\AppData\Local\Yarn\config\global\node_modules\.bin\maildev.cmd"   %*

Here are the same two files, generated when nodejs and yarn is installed in drive F.
File maildev.cmd found in the nodejs exe directory

"$basedir/C:/Users/user/AppData/Local/Yarn/config/global/node_modules/.bin/maildev.cmd"   "$@"
exit $?

File maildev.cmd.cmd found in the nodejs exe directory

@"%~dp0\C:\Users\user\AppData\Local\Yarn\config\global\node_modules\.bin\maildev.cmd"   %*

Also to note, running maildev.cmd.cmd instead of maildev makes maildev work.

I just noticed that this might be a duplicate of #2224 (didn't think of search for the windows tag)

[sharikovvladislav]

@modulexcite noticed #2224 (comment) that issue is fixed.
Can you try it again? I reinstalled yarn and now everything is fine.

[blindbox]

It works. Awesome, this has been a gamebreaker preventing me from using yarn completely.

Just in case, if anyone tried reinstalling and it still doesnt work, make sure you delete all traces of *.cmd and *.cmd.cmd files that yarn generated from previous installs, and try again.
