错误:使用本地依赖项时，jest-快速映射：@providesModule命名冲突
提问于 2018-10-20 12:51:16
我在package.json中使用一个本地模块，它也将react-native作为依赖项。
在我的应用package.json中
"react": "16.4.1",
"react-native": "0.56.0",
"react-native-services": "file:///Users/R01/Projects/react-native-services"在我的react-native-services package.json里
"react": "16.4.1",
"react-native": "0.56.0"因此，在运行react-native run-android时，Metro抛出：
Looking for JS files in
/Users/R01/Projects/RNApp
/Users/R01/Projects/react-native-services
Metro Bundler ready.

- 使用
npm和yarn(升级)安装，但是react-native run-android抛出的错误总是相同的。 - 所有rm -rf node_modules & npm安装rm -fr $TMPDIR/del* npm缓存干净的npm启动--重置缓存

rm -rf node_modules && npm install

同样的问题也解决了!！
项目中的所有npm包都有节点模块。确保包中的node_modules目录不应包括已经存在的节点模块。
在我的例子中，react-native存在于我的项目的node_modules中，以及另一个分叉库的node_modules中。
由于库是分叉的，我可以从其中删除node_modules目录，问题就解决了。

我自己回答。
作为一种临时解决方案，如果将依赖项放在peerDependencies中也不起作用，我已经将react和react-native放在了react-native-services包的devDependencies中。
