错误:jest-haste-map:使用本地依赖项时@providesModule命名冲突 [英] Error: jest-haste-map: @providesModule naming collision when using a local dependency

问题描述

我正在package.json中使用一个本地模块，该模块也具有react-native作为依赖项.

I'm using a local module in package.json that also has react-native as a dependency.

在我的APP 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中:

"react": "16.4.1",
"react-native": "0.56.0"

因此，在运行react-native run-android时，Metro Bundler会抛出:

So when running react-native run-android the Metro Bundler throws:

Looking for JS files in
   /Users/R01/Projects/RNApp
   /Users/R01/Projects/react-native-services 


Metro Bundler ready.

我已经尝试过:

• 同时安装了npm和yarn(已升级)，但是react-native run-android始终抛出相同的错误.
• watchman watch-del-all rm -rf node_modules&& npm install rm -fr $ TMPDIR/react- * npm cache clean npm start---reset-cache

• With both npm and yarn (upgraded) installations but react-native run-android throws always the same error.
• watchman watch-del-all rm -rf node_modules && npm install rm -fr $TMPDIR/react-* npm cache clean npm start -- --reset-cache

推荐答案

遇到同样的问题 解决了！！

Faced same issue Resolved it !!

项目中的所有npm软件包都具有节点模块. 确保包内的node_modules目录不应包含已经存在的节点模块.

All the npm packages in project have node modules. Make sure that node_modules directory inside packages should not include already present node module.

在我的情况下，react-native存在于我项目的node_modules和另一个分叉库的node_modules中.

In my case react-native was present in node_modules of my project as well as node_modules of another forked library.

由于库是分叉的，所以我可以从中删除node_modules目录，问题已得到解决.

As the library was forked, I could remove node_modules directory from it and the issue got resolved.
