当我运行(metagpt) D:\metagpt>python startup.py "Write a cli snake game based on pygame" --code_review True时，在中途得到这个错误，怎么解决呢？

I also get this error.

I am also getting this error, I tried to install Mermaid several times, to use Playwright, change the configuration, but nothing works, I still get similar errors, always ending on NotImplementedError, another part I get is that says the error is caused because requirement pool value is not a valid tuple.

This issue was caused by using the WindowsSelectorEventLoopPolicy in starup.py to fix #107. Howerer, on Windows, the default event loop ProactorEventLoop supports subprocesses, whereas SelectorEventLoop does not^[1]. We have now resolved #107 using a different approach and no longer need to utilize WindowsSelectorEventLoopPolicy to fix this issue.
