npm install
和
npm start

关于我如何应对我的机器启动的任何想法?
答案 0 :(得分:0)
您需要再次手动安装create-react-app
包。它会将所有依赖项安装到您的新计算机上,包括react-scripts
。
npm install create-react-app
它应该作为全局安装,而不是任何特定项目的一部分。

我有类似的经历,但就我而言,这是一个我在同一台机器上工作的项目。我将关闭PC,几天后再继续操作,但是当我运行npm start
时,我会得到您遇到的错误。
这是我的解决方法:
rm -rf node_modules
删除节点模块文件夹rm package-lock.json
npm cache clean --force
npm install
npm start
我再次遇到了类似的错误,这一次我已经在git中上传了我的项目,因此每次我要对其进行处理时,我都会执行git pull project_url
然后:
-npm install
-npm start
