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": "^6.6.0"
|
|
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:
|
|
/Users/sergio/Downloads/realm-tutorial-web/node_modules/eslint (version: 8.6.0)
|
|
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 /Users/sergio/Downloads/realm-tutorial-web/node_modules/eslint 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!
