node.js - 错误 : Couldn't find preset "react" when installed using npm install --global babel-preset-react but works without global flag

Question

我使用 npm install --global babel-cli 安装了 Babel CLI(版本 6)。然后我使用 npm install --global babel-preset-react 安装 react 预设。

然后我将项目目录中的 .babelrc 文件设置为

{
    "presets": ["react"]
}

当我尝试构建 JSX 文件时，它失败了

Error: Couldn't find preset "react"

如果我在没有 --global 标志的情况下安装预设(即安装在本地的 node_modules/文件夹中)，则构建工作。如何设置让 babel 使用全局预设？

您可以指定您尝试使用的预设的绝对(或相对)路径，例如:

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