npm install fdq fails with error

[joshtch]

There does not appear to be a way to install the NPM package.

Steps to reproduce:

$ mkdir test && cd test && npm init
<press enter 10 times>
$ npm install fdq

Error message:

> fdq@0.0.4 install </some/dir>/test/node_modules/fdq
> bin/create-git-hooks.sh

sh: bin/create-git-hooks.sh: No such file or directory
npm WARN test@1.0.0 No description
npm WARN test@1.0.0 No repository field.

This occurs with yarn as well:

$ yarn add fdq

Output:

This same issue and error message arises with fdo and fdp as well.

Ah, this only occurs when fdq is used as a git submodule. You can fix it by modifying bin/create-git-hooks.sh to

#!/bin/bash

echo "Symlinking pre-commit and commit-msg hooks from ${PWD}"

hooksdir="$(git rev-parse --git-dir)/hooks/"
bindir="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"

relpath() python -c 'import os.path, sys;\
  print os.path.relpath(sys.argv[1],sys.argv[2])' "$1" "${2-$PWD}"
relbindir="$(relpath "$bindir" "$hooksdir")"

ln -s "$relbindir/git-hook-pre-commit.sh" "$hooksdir/pre-commit"
if [ $? = 0 ]; then
  echo "$hooksdir/pre-commit -> $relbindir/git-hook-pre-commit.sh"
fi

ln -s "$relbindir/git-hook-commit-msg.sh" "$hooksdir/commit-msg"
if [ $? = 0 ]; then
  echo "$hooksdir/commit-msg -> $relbindir/git-hook-commit-msg.sh"
fi

ln -s "$relbindir/git-hook-prepare-commit-msg.sh" "$hooksdir/prepare-commit-msg"
if [ $? = 0 ]; then
  echo "$hooksdir/prepare-commit-msg -> $relbindir/git-hook-prepare-commit-msg.sh"
fi
