With a new version 12.1.5 of "@testing-library/react" running "npx create-react-app" fails with an ERESOLVE issue

[stas-litv]

Describe the bug

If you run "npx create-react-app Project-Name" after version 12.1.5 of @testing-library/react was released if will fail because current "cra-template" has "@testing-library/react": "^12.0.0" in its dependencies template for a new project. Version 12.1.5 of @testing-library/react requires "react": "<18.0.0" in its peer dependencies. That creates a conflict of dependencies.

Error report:

While resolving: test2@0.1.0
Found: react@18.0.0
node_modules/react
react@"^18.0.0" from the root project

Could not resolve dependency:
peer react@"<18.0.0" from @testing-library/react@12.1.5
node_modules/@testing-library/react
@testing-library/react@"^12.0.0" from the root project

I came across this problem, too!

Why you closed this? @stas-litv Did you solve this problem?

[stas-litv]

Closed the issue because the problem was in npm cache of my computer.
The dependencies list was already updated three days ago and now it contains ^13.0.0 of @testing-library/react

How did you fix the issue? I have the same problem. Thanks in advance.

[stas-litv]

Sorry, didn't check everything. The problem is still active for me. I'm reopening it.
It will be fixed in version 5.0.1 (pull request is already approved), but at this moment it doesn't work.

[DailyDisco]

Ah okay, so we just need to wait for an update?

Looks like we need to wait, I don't know for sure. That's why I reopened the issue.
I'm waiting for someone to comment it.

Pull request that fixes it: #12223

I'm also experiencing this issue.

This is happening to me too.

Same issue here

CRA 5.0.0 was released many months ago. I wonder why they did not notice this many months ago?
