错误：纱线启动-找不到错误命令“开始”

Question

我正在努力学习React，我正在使用一个私人回购开始。

我在repo目录中运行yarn start，但得到错误消息：

yarn run v1.13.0
error Command "start" not found.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

我已经安装了节点和纱线。

v10.15.0
node is /usr/local/bin/node

1.13.0
yarn is /usr/local/bin/yarn

}

Answer 1

在package.json文件的脚本中没有start命令。

"scripts": {
  "start": "some command to be run", // you need to add this line
  "test": "(eslint lib || true) && jest"
}

也许您想运行test命令-npm test/yarn test？
