我想在我的 React Native 项目中使用 babel-plugin-module-alias 将模块路径从 ../../../../components/foo 转换为 app/components/foo

我试图在两个地方独立修改 babel 配置,但都不起作用。

一,在我项目的根目录 index.ios.js 旁边:

{
  "plugins": [
    ["babel-plugin-module-alias", [
      { "src": "./app", "expose": "app" }
    ]]
  ]
}

还有两个,在 /node_modules/react-native/packager/react-packager/.babelrc :
{
  "retainLines": true,
  "compact": true,
  "comments": false,
  "plugins": [
    ["babel-plugin-module-alias", [
      { "src": "./app", "expose": "app" }
    ]],
    "syntax-async-functions",
    "syntax-class-properties",
    "syntax-trailing-function-commas",
    "transform-class-properties",
    "transform-es2015-arrow-functions",
    "transform-es2015-block-scoping",
    "transform-es2015-classes",
    "transform-es2015-computed-properties",
    "transform-es2015-constants",
    "transform-es2015-destructuring",
    ["transform-es2015-modules-commonjs", {"strict": false, "allowTopLevelThis": true}],
    "transform-es2015-parameters",
    "transform-es2015-shorthand-properties",
    "transform-es2015-spread",
    "transform-es2015-template-literals",
    "transform-flow-strip-types",
    "transform-object-assign",
    "transform-object-rest-spread",
    "transform-react-display-name",
    "transform-react-jsx",
    "transform-regenerator",
    "transform-es2015-for-of"
  ],
  "sourceMaps": false
}

它不会抛出任何错误,只是尝试要求一个模块,因为 import MyComponent from 'app/components/MyComponent'; 会产生错误:
Unable to resolve module app/components/MyComponent from .... Invalid directory /Users/node_modules/app/components/MyComponent

我试过核对我所知道的每个缓存:
watchman watch-del-all
rm -rf $TMPDIR/react-*
./node_modules/react-native/packager/packager.sh start --resetCache

任何进一步的想法将不胜感激!

最佳答案

将 npm/node/react-native/react 升级到最新版本后:

react-native: ^0.29.0
react: 15.2.1
npm: 3.10.3
node: 6.3.0

然后:
watchman watch-del-all
npm start -- --reset-cache

这个问题就过去了。
