无法通过npm脚本运行babel“babel：command not found” [英] Unable to run babel via npm script "babel: command not found"

问题描述

要开始，我跑了：

npm install --save-dev babel-cli
npm install --save-dev babel-preset-es2015
npm install --save-dev babel-preset-stage-0 

这是我的package.json：

Here is my package.json:

   {
      "scripts": {
        "build": "babel src -d dist"
      },
      "devDependencies": {
        "babel-cli": "^6.6.5",
        "babel-core": "^6.7.2",
        "babel-preset-es2015": "^6.6.0",
        "babel-preset-stage-0": "^6.5.0"
      }
    }

这是我的.babelrc文件：

Here is my .babelrc file:

{
  "presets": ["es2015", "stage-0"]
}

我的文件结构如下：

- Root
    - src
        - client 
        - server
        - test  
    - dist 
    - package.json

我正在调用npm run build from根文件夹。我期待它将源文件夹编译到dist文件夹中。它运行然后我收到此错误：

I am calling npm run build from the root folder. I am expecting it to compile the source folder into the dist folder. It runs and then I get this error:

> babel src -d dist

sh: babel: command not found

所以你可以看到，我已经安装了babel-cli，我已经安装了预设，我认为根据babel文档的所有内容都是有序的。

So as you can see, I've installed babel-cli, I've installed the presets, and I think everything is in order according to the babel docs.

有没有人知道为什么它不起作用？我可以错过一个babel npm文件吗？ babel src -d dist是不正确的？

Does anyone have ideas about why it wouldn't be working? Could I be missing a babel npm file? Is "babel src -d dist" incorrect?

感谢您提供的任何帮助！

Thanks for any help you can provide!

我制作了另一个文件夹并按照相同的步骤进行操作完美。由于某种原因，它无法在此目录中工作。

I made another folder and followed the same steps, it worked perfectly. For some reason it's not working in this directory.

推荐答案

您是否运行npm install来安装开发包？

Did you run "npm install" to install the dev packages?
