[英]Babel plugin (babel-plugin-module-alias) with React Native
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
。
我试图在两个地方分别修改babel的配置,但都没有用。
一个,在我的项目的根目录下, index.ios.js
:
{
"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
}
它不会引发任何错误,只需尝试import MyComponent from 'app/components/MyComponent';
这样的模块即可import MyComponent from 'app/components/MyComponent';
产生错误:
Unable to resolve module app/components/MyComponent from .... Invalid directory /Users/node_modules/app/components/MyComponent
。
我尝试对我知道的每个缓存进行核对:
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!
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
这个问题消失了。
