Question

我有一个软件包，它本身在package.json中有一个脚本，我希望能够在我的顶级项目中运行。这个包是我的顶级项目依赖项之一。我正在寻找一种直接或间接调用依赖包脚本的方法。

我们假设我使用的模块名称为foo，我想要运行的脚本是updateFooData。

我尝试使用语法npm run-script <package> <...>来运行它，但这似乎是不推荐使用的功能，因为我无法在当前official documentation中找到它，但我在其他地方看到它（非常古老））搜索结果。

npm run-script foo updateFooData

# npm ERR! missing script: foo

我也查看了npm api，虽然npm.commands.run-script(args, callback)会做我想做的事，但我无法弄清楚如何将模块加载到npm

{
  ...
  "scripts":{
    "foo:updateFooData": "node --eval \"... ??; npm.commands.run-script('updateFooData', callback)\""
  }
}

npm run foo:updateFooData
# Obviously fails

我发现到目前为止唯一可行的方法是将CD放入子模块目录并从那里运行npm。这不是我的首选解决方案。

cd node_modules/foo
npm run updateFooData

我遇到了这个尝试运行geoip-lite的updatedb脚本。您应该使用npm explore command，它将在依赖项中生成一个新的shell＆＃39; 。目录

因此，对于您的使用案例，请尝试npm explore foo -- npm run updateFooData

Note:

This isn't a very good idea. You have no guarantee which node_modules folder module will be installed in as NPM will attempt to optimise space by installing shared packages at the highest level possible. – @superluminary

Something I've found that does work:

If the script you are running runs a script file, you can look at the path of the file it's running and run the script using a require:

# if node_modules/foo/package.json looks like this
{
  "scripts": {
    "updateFooData":"scripts/updateFooData.js"
  }
}

# then package.json can look like this
{
  "scripts": {
    "foo:updateFooData":"node --eval \"require('foo/scripts/updateFooData.js')\""
  }
}

# or package.json can look like this
{
  "scripts": {
    "foo:updateFooData":"node node_modules/foo/scripts/updateFooData.js"
  }
}

# and you can run it like this
npm run foo:updateFooData

I don't like this solution because it only works if the npm script you are running is a file. It won't apply in all
