I just got a similar error for the first time today. It appears in \node_modules\metro-config\src\defaults\blacklist.js, there is an invalid regular expression that needed changed.

Looks like they changed how the create-react-app utilizes a proxy. Remove the proxy from the package.json. Then… Add this package: npm i -S http-proxy-middleware Then create a setupProxy.js in src: src/setupProxy.js const proxy = require(“http-proxy-middleware”); module.exports = app => { app.use(proxy(“/api/*”, { target: “http://localhost:5000/” })); }; Now from inside the React component, you can do … Read more
I also encountered this problem too and I’ve found a workaround. First, you need to install the two loaders(file-loader, url-loader). e.g. $ npm install –save file-loader url-loader If you want to support the css. Make sure you install the style loaders. e.g., $ npm install –save style-loader css-loader Next, you update the webpack config, kindly … Read more
