无效尝试

常见但无效的做法:

  1. 70% 失败

    Runtime imports may resolve to the wrong version and fail with AttributeError or ImportError.

  2. 60% 失败

    Force-reinstall may pull in conflicting transitive deps and break other packages in the same env.

  3. 95% 失败

    Removes the package you need instead of resolving the conflict.
