推荐答案

我有过类似的经历，但就我而言，这是一个我在同一台机器上工作的项目.我会关闭电脑，几天后继续，但是当我运行 npm start 时，我会收到您遇到的错误.

I had a somewhat similar experience but in my case it was a project that I'm working on my same machine. I'd turn off PC, come after a few days to continue but when I run npm start I'd get the error you are having.

我是这样解决的:

• 导航到我的项目目录
• rm -rf node_modules 删除节点模块文件夹
• rm package-lock.json
• npm 缓存清理 --force
• npm install
• npm start

• Navigated to my project directory
• rm -rf node_modules to delete the node modules folder
• rm package-lock.json
• npm cache clean --force
• npm install
• npm start

我又遇到了类似的错误，这次我已经在git中上传了我的项目，所以每次我想处理它时，我都会做一个git pull project_url然后:- npm 安装- npm start

I ran into a similar error again, this time I had already uploaded my project in git, so each time I want to work on it, I'd do a git pull project_url then: - npm install - npm start
