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：

  Referenced from: /robofriends/node_modules/webpack-dev-server/node_modules/fsevents/build/Release/fse.node<br>

【问题讨论】：

标签： create-react-app yarnpkg npm-start

【解决方案1】：

我认为是纱线开始，而不是纱线开始。而在此之前， cd 表示“更改目录”。您必须执行cd robofriends（因为是目录的名称）才能进入目录，然后运行命令yarn start。
