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 npm ERR!

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？
