如何从已经安装的NPM软件包中运行脚本？

Question

Example:

npm install my-tools
npm run my-tools tool1

This doesn't work - it looks for a "package.json in my current directory. The documentation for "npm run" says:

If no package name is provided, it will search for a package.json in the current folder

( https://docs.npmjs.com/cli/run-script )

So how can I provide a package name?

Answer 1

It looks like you're trying to run a script defined in the package.json of my-tools . This functionality is not supported as of npm@2.0.0 .

The reference to npm run-script taking a package name is a documentation error; I have created an issue for that on the npm issue tracker: https://github.com/npm/npm/issues/7440

Some alternatives might include:

1. using npm explore to temporarily set current directory (etc.) into the package, eg, npm explore my-tools -- npm run tool1

2. publishing tool1 etc. as bin entries in package.json instead of as scripts ; this will make them accessible via the command line

3. depending on your needs, you may find a more heavyweight task runner such as grunt is a better approach than npm scripts and binaries
