我克隆了一个包含以下内容的react项目package.json。之后yarn，yarn start给了我以下错误。我试过了yarn add react-scripts start，但是还是没用。

我正在使用MacOS。

有人可以帮忙吗？

$ yarn start
yarn run v1.21.1
$ SET PORT=8000 && react-scripts start
/bin/sh: SET: command not found
error Command failed with exit code 127.

我认为您正在寻找的是在执行命令之前设置环境变量：PORT=8000 react-scripts start，因为Linux / Unix系统不像Windows那样使用SET命令来设置环境变量

如果遇到react-scripts找不到命令的问题，请使用以下命令直接引用软件包的本地版本：PORT=8000 ./node_modules/.bin/react-scripts start
