Hi team,

Hi.

Unfortunately, we cannot reproduce the problem. We will be able to help you if you send us a small sample project that demonstrates the issue.

What is the node and npm version in your env?

I have node.js v15.10.0 and npm 7.5.3

#7

I use npm v7.6.3 and node.js v14.15.5

#8

Thank you for your response! Reminds me that newer node or npm will do strict deps check and cause the problem.

googled and find node.js - Error when trying to install react-redux dependency - Stack Overflow

Then tried with below command resolved the issue.

npm i --legacy-peer-deps
#9

I have upgraded now Node.js to v.15.12.0 and your issue has been reproduced.

There is a known Github issue about problem with npm install using npm 7.

Using Node.js v14.16.0 (LTS version) resolved the issue in my case.

Regards,
Nadezhda.

Yes, I also tried to downgrade node.js to 14 and see the issue is gone.

Since this is a known issue, hopefully it could be resolved some day, because the root cause is mismatched deps. But for now, we can suggest developers to install LTS version of node.js to avoid this problem.
