我可以从 package.json bin 脚本运行命令吗？

Question

Is it possible to run a command from a bin script in a package.json ? I know it expects a path to file and trying to run a command there results in an error upon installation (after publishing to npm). Is it possible to run a command like it is in an npm start ?

Examples:

{
  "name": "myscript",
  "version": "1.0.3",
  "bin": {
    "myscript": "app/main.js"
  }
}

This will create a symlink from the app/main.js script to /usr/local/bin/myscript
Instead, this is what I want to achieve:

{
  "name": "myscript",
  "version": "1.0.3",
  "bin": {
    "myscript": "echo hello world"
  }
}

Possible workarounds are also appreciated.

Answer 1

Based on what you've written, it seems like you are looking for https://docs.npmjs.com/cli/run-script .

With the package.json script property, you can define scripts as arbitrary shell commands or programs installed into the ./node_modules/.bin .

您是否尝试过运行npm link https://docs.npmjs.com/cli/link这将创建指向您的二进制文件的链接，然后您可以在命令行上以myscript运行您的脚本。
