错误:使用npm install安装时无法找到预设"react"--global babel-preset-react但是没有全局标志

Question

我使用了安装Babel CLI(版本6)npm install --global babel-cli.然后我使用安装反应预设npm install --global babel-preset-react.

然后我.babelrc将项目目录中的文件设置为

{
    "presets": ["react"]
}

当我尝试构建一个JSX文件时,它失败了

Error: Couldn't find preset "react"

如果我安装没有--global标志的预设(即在本地安装在node_modules /文件夹中),那么构建工作.我如何设置让babel使用全局预设？

您可以指定要尝试使用的预设的绝对路径(或相对路径),例如:

babel --presets /usr/local/lib/node_modules/babel-preset-react --watch jsx/ --out-dir js/
