django无法安装mysqlclient

Question

我在 django 框架中使用最新的 python 版本 3.11，为此我需要安装 mysqlclient。 但是我尝试安装时出现错误

pip install mysqlclient 

Output 这样的错误：

Building wheels for collected packages: mysqlclient
  Building wheel for mysqlclient (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py bdist_wheel did not run successfully.

      error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools
/
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.

任何想法都可以解决吗？

Answer 1

你显然在 Windows，所以你想确保pip尝试使用mysqlclient的二进制包，而不是尝试从头开始构建一个：

pip install mysqlclient --only-binary=mysqlclient

但是，这可能会安装旧版本的mysqlclient ，因为您正在使用的 32 位 Python 3.11没有二进制包。 如果您的机器能够运行 64 位版本，我强烈建议您改用它，因为在不久的将来，32 位支持可能会越来越少。
