javascript – 无法通过npm脚本运行babel“babel：command not found”

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：

{
      "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：

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

我的文件结构是这样的：

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

我从根文件夹调用npm run build.我期望它将源文件夹编译到dist文件夹中.它运行,然后我得到这个错误：

> 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,我认为一切都是按照babel文档顺序的.

有人有什么想法,为什么它不会工作？我可能会错过一个babel npm文件吗？ “babel src -d dist”不正确吗？

感谢您的任何帮助,您可以提供！

我做了另一个文件夹,并按照相同的步骤,它的工作完美.由于某种原因,它不能在此目录中工作.

解决方法

您是否运行“npm install”安装开发包？
