未全局安装npm包时，能否通过CMD进入包目录执行CLI命令？

Hey there! Let's tackle your questions about using npm package CLIs without global installs:

There are a few reliable, developer-friendly ways to do this:

• Use npx: This is the simplest and most widely used method. Since npm 5.2+, npx comes bundled with npm out of the box. Just run:

  npx <package-name> <your-desired-command>
  

  For example, to spin up a new React app without installing Create React App globally, you’d use npx create-react-app my-new-project. npx temporarily downloads the package, runs the CLI command, and cleans up the temporary files afterward—no leftover clutter.
• Call the local node_modules/.bin script: If you’ve already installed the package to your project (via npm install <package-name>), the CLI executable lives in the node_modules/.bin directory. You can run it directly with:
  • On macOS/Linux:

    ./node_modules/.bin/<cli-command-name>
    

  • On Windows CMD:

    .\node_modules\.bin\<cli-command-name>
    

• Add a script to package.json: Perfect for commands you run regularly. Open your project’s package.json and add a line under the scripts section:

  "scripts": {
    "my-cli-task": "<cli-command-name>"
  }
  

  Then run it with:

  npm run my-cli-task
  

  npm automatically adds the node_modules/.bin directory to the PATH when executing scripts, so you don’t need to type the full file path.

Yes, you can—but it’s not the most convenient approach, since it depends on how each package structures its files. Here’s how it works:

1. First, ensure you’ve installed the package locally (run npm install <package-name> in your project root).
2. Navigate to the package’s folder inside node_modules. For example, if the package is named my-cli-tool, you’d run:

   cd node_modules\my-cli-tool
   

3. Check the package’s own package.json to find the CLI entry point (look for the bin field). This might be a file in a bin subfolder, or a direct file in the package root.
4. Run the CLI using Node.js. For example, if the entry point is bin/cli.js, you’d run:

   node bin/cli.js
   

That said, this method is tedious because you have to hunt down the exact CLI file path (which varies between packages). Using npx or npm scripts is almost always a more consistent, less hassle-free choice.
