如何解决创建React应用时出现纱线错误代码1
当我使用npx create-react-app名称创建一个react应用并且尝试启动该应用时,我得到了退出代码1的错误,更具体地说,这就是那个
It is likely not a bug in Create React App,but something you need to fix locally.
The react-scripts package provided by Create React App requires a dependency:
"webpack-dev-server": "3.11.0"
Don't try to install it manually: your package manager does it automatically.
However,a different version of webpack-dev-server was detected higher up in the tree:
/Users/tudor/node_modules/webpack-dev-server (version: 3.10.3)
Manually installing incompatible versions is known to cause hard-to-debug issues.
If you would prefer to ignore this check,add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That will permanently disable this message but you might encounter other issues.
To fix the dependency tree,try following the steps below in the exact order:
1. Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
2. Delete node_modules in your project folder.
3. Remove "webpack-dev-server" from dependencies and/or devDependencies in the package.json file in your project folder.
4. Run npm install or yarn,depending on the package manager you use.
In most cases,this should be enough to fix the problem.
If this has not helped,there are a few other things you can try:
5. If you used npm,install yarn (http://yarnpkg.com/) and repeat the above steps with it instead.
This may help because npm has known issues with package hoisting which may get resolved in future versions.
6. Check if /Users/tudor/node_modules/webpack-dev-server is outside your project directory.
For example,you might have accidentally installed something in your home folder.
7. Try running npm ls webpack-dev-server in your project folder.
This will tell you which other package (apart from the expected react-scripts) installed webpack-dev-server.
If nothing else helps,add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That would permanently disable this preflight check in case you want to proceed anyway.
P.S. We know this message is long but please read the steps above :-) We hope you find them helpful!

如果我尝试启动一个较旧的应用程序,则可以尝试执行该步骤,但仍然出现错误
解决方法
我用npm i webpack-dev-server
安装了webpack-dev-server
尝试通过yarn remove webpack-dev-server
删除webpack-dev-server并将版本3.11.0作为yarn add webpack-dev-server@3.11.0
安装
