错误:找不到预设的“反应"当使用npm install安装时--global babel-preset-react但可以在没有全局标志的情况下工作 [英] Error: Couldn't find preset "react" when installed using npm install --global babel-preset-react but works without global flag

问题描述

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.

I installed Babel CLI (version 6) using npm install --global babel-cli. I then install react preset using npm install --global babel-preset-react.

然后我将项目目录中的.babelrc文件设置为

I then setup the .babelrc file in the project directory to

{
    "presets": ["react"]
}

当我尝试构建JSX文件时，它失败并

When I try to build a JSX file it fails with

Error: Couldn't find preset "react"

如果我安装不带--global标志的预设(即安装在本地的node_modules/文件夹中)，则构建有效.如何设置以使babel与全局预设一起使用?

If I install the preset without --global flag (i.e. installs in node_modules/ folder locally) then the build works. How do i set up to get babel to work with a global preset?

推荐答案

您可以指定要使用的预设的绝对(或相对)路径，例如:

You can specify the absolute (or relative) path to the preset you are trying to use, e.g:

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