如何从另一个项目中排除node_modules,同时仍然使用JS组件

Question

---

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,而是以某种方式将其从(a)中拉出来.

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,你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**).

由于某些原因,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.

通过重新连接注入的config-overides.js(稍微更改创建反应应用程序webpack)
