Question

我在Mac终端中创建了一个React应用：

npx create-react-app robofriends
cd my-app
yarn-start

我收到以下错误：

dyld: lazy symbol binding failed: Symbol not found: _FSEventStreamCreate<br>
  Referenced from: /robofriends/node_modules/webpack-dev-server/node_modules/fsevents/build/Release/fse.node<br>

NPM版本：6.14.8

macOS Catalina版本10.15.5

我认为是纱线启动，而不是纱线启动。之前，cd 的意思是“更改目录”。您必须执行 class Parent<T: Parent>（因为是目录名称）才能进入目录，然后运行命令 cd robofriends。

npx create-react-app后，yarn start不起作用
