Problems on Windows - Help! No such file or directory 2: ./node_modules/pre-commit/hook : integer expression expected: [: 127 : numeric argument required 5:

[replete]

I've been pulling my hair out trying to make sense of this for someone I'm working with who is having this problem. It's breaking their workflow.

No such file or directory 2: ./node_modules/pre-commit/hook
: integer expression expected: [: 127
: numeric argument required 5:

I've tried Windows machines near me, and VMs and don't have the problem.

This happens in cmd, powershell, MinGW, WebStorm.

Any ideas?

Same problem with babun on Windows 7, I got this when I try to commit :

: No such file or directory     .git/hooks/pre-commit: line 2: ./node_modules/pre-commit/hook
: integer expression expected   .git/hooks/pre-commit: line 4: [: 127
: numeric argument required     .git/hooks/pre-commit: line 5: exit: 0

Hope we'll find a solution

Same here on Windows 10 in WSL Bash

Same on Windows 7

If you open up .git/hooks/pre-commit, you can see that the code is written in bash:

#!/bin/bash
./node_modules/pre-commit/hook
RESULT=$?
[ $RESULT -ne 0 ] && exit 1
exit 0

Interestingly enough, I get the same message in Cygwin, but I don't in Git bash's mingw64.

In any case, the problem is probably something something doesn't understand bash.

Cygwin:

$ uname -r
2.10.0(0.325/5/3)

$ git --version
git version 2.16.2

Git bash:

$ git --version
git version 2.5.0.windows.1

EDIT: this is a red herring. See next comment for details.

Update: looks like .git/hooks/pre-commit was not happy about the line ending. It had \r\n (Windows). Switching to \n got me further.

EDIT: looks like it purposely chooses Windows line ending (https://github.com/observing/pre-commit/blob/f25888ffc67d21beaa1572b53ab6704a67266b64/install.js#L104-L108). Maybe it shouldn't(?).

I suspect the problems I am encountering are specific to Cygwin, so if you're not using Cygwin, give the above a shot.

This is the full error after changing the line endings:

> git commit -m "test"
/cygdrive/c/Program Files/nodejs/node
pre-commit:
pre-commit: Received an error while parsing or locating the `package.json` file:
pre-commit:
pre-commit:   Cannot find module '\cygdrive\c\path\to\package.json'
pre-commit:
pre-commit: Skipping the pre-commit hook.
pre-commit:

It looks like it's failing on https://github.com/observing/pre-commit/blob/f25888ffc67d21beaa1572b53ab6704a67266b64/hook#L49.

I am using Cygwin Git with a Windows Node installation. This makes sense to me, since Windows Node probably doesn't understand a non-Windows path.

Using "C:\Program Files\Git\bin\git" commit -m "test" works for me, and surprisingly, with pre-commit containing either line ending. Looks like Windows Git with Windows Node installation works out-of-the-box.

Hopefully this helps!

In node_modules/pre-commit/index.js change line

this.json = require(path.join(this.root, 'package.json'));

to

this.json = require(path.join(this.root, 'package.json').replace(/\\([a-zA-Z])\\/, '$1:\\'));

This will change \c\Users\rofrol\project1\package.json to c:\Users\rofrol\project1\package.json.
