我不得不重新安装我编码的 linux VM(出于学校目的(，在重新分叉和克隆我的应用程序后，我无法启动服务器。我已经运行了我相信的必要步骤，创建和迁移了数据库，捆绑了 intall，并安装和重新安装node_modules......我有一个耙子任务，可以同时为我启动 api 和网页。现在如果我耙开始...这是我的错误消息...我已经按照错误消息上的说明进行操作，但没有成功...不确定我是否在这里错过了什么。

10:12:39 web.1 | There might be a problem with the project dependency tree.
10:12:39 web.1 | It is likely not a bug in Create React App, but something you need to fix locally.
10:12:39 web.1 |
10:12:39 web.1 | The react-scripts package provided by Create React App requires a dependency:
10:12:39 web.1 |
10:12:39 web.1 | "babel-eslint": "10.0.1"
10:12:39 web.1 |
10:12:39 web.1 | Don't try to install it manually: your package manager does it automatically.
10:12:39 web.1 | However, a different version of babel-eslint was detected higher up in the tree:
10:12:39 web.1 |
10:12:39 web.1 | /home/learn/Development/Code/hoop-it-up/node_modules/babel-eslint (version: 10.0.3)
10:12:39 web.1 |
10:12:39 web.1 | Manually installing incompatible versions is known to cause hard-to-debug issues.
10:12:39 web.1 |
10:12:39 web.1 | If you would prefer to ignore this check, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
10:12:39 web.1 | That will permanently disable this message but you might encounter other issues.
10:12:39 web.1 |
10:12:39 web.1 | To fix the dependency tree, try following the steps below in the exact order:
10:12:39 web.1 |
10:12:39 web.1 | 1. Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
10:12:39 web.1 | 2. Delete node_modules in your project folder.
10:12:39 web.1 | 3. Remove "babel-eslint" from dependencies and/or devDependencies in the package.json file in your project folder.
10:12:39 web.1 | 4. Run npm install or yarn, depending on the package manager you use.
10:12:39 web.1 |
10:12:39 web.1 | In most cases, this should be enough to fix the problem.
10:12:39 web.1 | If this has not helped, there are a few other things you can try:
10:12:39 web.1 |
10:12:39 web.1 | 5. If you used npm, install yarn (http://yarnpkg.com/) and repeat the above steps with it instead.
10:12:39 web.1 | This may help because npm has known issues with package hoisting which may get resolved in future versions.
10:12:39 web.1 |
10:12:39 web.1 | 6. Check if /home/learn/Development/Code/hoop-it-up/node_modules/babel-eslint is outside your project directory.
10:12:39 web.1 | For example, you might have accidentally installed something in your home folder.
10:12:39 web.1 |
10:12:39 web.1 | 7. Try running npm ls babel-eslint in your project folder.
10:12:39 web.1 | This will tell you which other package (apart from the expected react-scripts) installed babel-eslint.
10:12:39 web.1 |
10:12:39 web.1 | If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
10:12:39 web.1 | That would permanently disable this preflight check in case you want to proceed anyway.
10:12:39 web.1 |
10:12:39 web.1 | P.S. We know this message is long but please read the steps above :We hope you find them helpful!

好的，我想出了问题，根目录中新生成的 .env 的 SKIP_PREFLIGHT_CHECK=true 起到了作用，我想因为我的 babel-eslint 版本高于要求，跳过应该没问题，服务器启动没有问题。感谢您的反馈以帮助我解决问题！！
