我试图在react中运行我的项目，但是当试图运行警告时出现:
> crud2@0.1.0 start
> react-scripts start
There might be a problem with the project dependency tree.
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:
"eslint": "5.6.0"
Don't try to install it manually: your package manager does it automatically.
However, a different version of eslint was detected higher up in the tree:
C:UsersJose Djalmanode_moduleseslint (version: 8.28.0)
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 "eslint" 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 C:UsersJose Djalmanode_moduleseslint is outside your project directory.
For example, you might have accidentally installed something in your home folder.
7. Try running npm ls eslint in your project folder.
This will tell you which other package (apart from the expected react-scripts) installed eslint.
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!
我已经尝试使用npm,yarn请求的命令，我已经在最后删除了node_modules，我已经尝试做了很多，所以我试图安装eslint的5.6.0版本，使用命令yarn add eslint@5.6.0，也尝试了npm i eslint@5.6.0。但由于某些原因，当我执行这些命令时，eslint的版本。是8.28.0，这对我来说没有意义，有人能帮助我吗?
您可以尝试删除yarn.lock或package-lock.json，并在通过rm -rf node_modules删除node_modules文件夹后再次使用yarn或npm i安装软件包。
rm -rf node_modules
rm yarn.lock
yarn
或
rm -rf node_modules
rm package-lock.json
npm i
要安装eslint的确切版本，您可以运行npm i --save --save-exact eslint@5.12.0或yarn add --exact eslint@5.12.0
希望有帮助!
