I installed the latest version of react devtools on the V3 branch. I installed it according to a series of operations in the official documents, and then ran the project to report an error:

However, the previous project was running normally, so I searched the Internet and found that most of them said that the plug-in react devtools was disabled directly, and there was no language. Why do I install it??Too much memory??

So I looked at the error message again, and then commented out the code used in my project according to the following error message

according to its path, and then re yarn start, there was no error message

I read it online and said that this is the reason for the version. I said that the previous version did not have this problem
just sauce, bye!
