更新：由于某种原因，我无法重现问题，但无法解决问题 . 为其他人留下更新的配置详细信息 .

我有2个项目，一个用于React Native，另一个用于React . 来自React Web Project（例如rp1.js）的源文件正在使用来自React Native项目的源文件mycommonrn.js（component） .
问题是mycommonrn.js文件正在使用NPM模块（react-native-vector-icons） . 我将这个模块分别安装在两个模块中：

  • （a）在React Native项目下的node_modules中

  • （b）在React项目下的node_modules中 .

当从React Web项目使用mycommonrn.js时，我需要从 ( b ) 中的node_modules中提取该NPM模块 . 但这并没有发生，而是以某种方式从 ( a ) 拉出来 .

导致问题的import语句位于mycommonrn.js中

import Ionicons from 'react-native-vector-icons/dist/Ionicons';

我试图指示webpack babel-loader不要在react-native项目中查看node_modules ..但它不起作用...

我的应用程序使用Create React App设置重新连接，以覆盖CRA强加的目录监狱 .

我的配置如下，您可以看到我明确告诉babel-loader“排除”给我带来麻烦的node_modules目录（为了便于阅读，标有**） .

由于某种原因，明确排除不起作用 . （CRA设置不使用.babelrc - 这就是我不在帖子中发布的原因） .

提前感谢任何帮助 .
