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

问题描述

我在 package.json 中使用了一个本地模块，该模块也有 react-native 作为依赖项.

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

在我的应用程序 package.json 中:

In my APP package.json:

"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"

所以当运行 react-native run-android 时，Metro Bundler 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.

我已经试过了:

• 使用 npm 和 yarn(升级)安装但 react-native run-android 总是抛出相同的错误.
• 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

面临同样的问题解决了！！

Faced same issue Resolved it !!

项目中所有的 npm 包都有 node 模块.确保包内的 node_modules 目录不应包含已存在的节点模块.

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

就我而言，react-native 出现在我项目的 node_modules 以及另一个分叉库的 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.

由于库被分叉，我可以从中删除 node_modules 目录，问题得到解决.

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