React应用程序安装后无法编译

Question

运行安装脚本后，服务器启动并提供一个页面，在“未能编译行”之后显示相同的文本。

我正在运行Windows10和自动更新刚刚更新了我的电脑今天，就在我做创建-反应-快速安装之前。

PS H:\mern-passport> npm start

> mern@1.0.0 start H:\mern-passport
> if-env NODE_ENV=production && npm run start:prod || npm run start:dev


> mern@1.0.0 start:dev H:\mern-passport
> concurrently "nodemon --ignore 'client/*'" "npm run client"

似乎是autoprefixer最新版本的一个问题。我引用了https://github.com/postcss/autoprefixer/issues/1328，并尝试在我的项目中降级autoprefixer，它现在起作用了。尝试：

npm install autoprefixer@9.8.0

编码快乐！
