reactjs – 使用React Native的Babel插件(babel-plugin-module-alias)

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index.ios.js旁边的项目的根目录：

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

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,只是试图要求一个模块从’app / components / MyComponent’导入MyComponent;产生错误：

无法解决模块app / components / MyComponent ….无效的目录/ Users / node_modules / app / components / MyComponent.

我已经尝试了我知道的每个缓存：

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！

升级npm / node / react-native /对其最新的响应后：

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

这个问题消失了.
