我想要使用babel-plugin-module-alias来将React Native项目中的模块路径从../../../../components/foo转换为app/components/foo。
我尝试在两个地方独立修改了babel配置，但都没有成功。
首先是在项目根目录下，在index.ios.js旁边：
{
"plugins": [
["babel-plugin-module-alias", [
{ "src": "./app", "expose": "app" }
]]
]
}
同时，还需要在/node_modules/react-native/packager/react-packager/.babelrc中进行以下两个操作：
{
"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，只是尝试使用import MyComponent from 'app/components/MyComponent';这样的方式来要求一个模块，但会出现以下错误：
无法解析模块 app/components/MyComponent .... 无效目录 /Users/node_modules/app/components/MyComponent.
我已经尝试清除我所知道的所有缓存：
watchman watch-del-all
rm -rf $TMPDIR/react-*
./node_modules/react-native/packager/packager.sh start --resetCache
非常感谢任何进一步的想法！
