添加 git 钩子以监视文件的更改

Question

我正在尝试创建一个评估软件包的git挂钩。JSON更改并自动运行shinkwrapper，并将更改的文件提交为存储库。我尝试了很多，但无法找到工作解决方案。有人知道这是怎么回事吗？

另外，每当我添加npm模块并尝试运行NPM缩水时，我都会得到此错误

 npm ERR! Darwin 16.7.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "shrinkwrap"
npm ERR! node v6.11.3
npm ERR! npm  v3.10.10
npm ERR! Problems were encountered
npm ERR! Please correct and try again.

npm ERR! Please include the following file with any support request:
npm ERR!     /Users/maxDoung/Desktop/Redux-React/npm-debug.log

出于某种原因，如果我手动更新package.json或使用NPM安装模块，则NPM收缩不起作用。另外，我不确定节点或NPM版本是否重要。我使用的是NPM 3.10.10和节点V6.11.3

这是我的依赖性

Answer 1

这可能是您想要的，或者至少会指向正确的方向。我已经在Linux上进行了测试。

请按照以下步骤（根据您的特定需求进行调整）：

1-在 .git/hooks/pre -commit 上放置以下文件：

#!/bin/bash
is_package_json_at_git_index() {
  echo "> Getting list of files at git index."
  # Get the list of files added to the git index and verify that package.json is there.
  git diff --cached --name-only | grep -x package.json
}
update_shrinkwrap_and_at_to_git_index() {
  echo "> Updating npm-shrinkwrap.json and adding to this commit."
  # Run shrinkwrap in the case that it was never ran
  npm shrinkwrap
  # Install dependencies that could be added to package.json and update npm-shrinkwrap.json
  npm install
  # Add the updated- npm-shrinkwrap.json to the git index so we include it in the current commit
  git add npm-shrinkwrap.json 
}
if is_package_json_at_git_index; then
  update_shrinkwrap_and_at_to_git_index
fi

2-将运行权限添加到预先承担的权限 chmod +x .git/hooks/pre-commit

现在，如果您执行以下操作：

1. 您可以手动包装。
2. 您运行git add package.json
3. 您运行git commit -m "Your commit message"

以下会发生：

1. npm-shrinkwrap.json将被更新
2. npm-shrinkwrap.json将自动添加到提交

注意：您可以使用其他钩子，请在此处查看它们的详细说明。
