How to fix "ValueError: invalid literal for int() with base 10: '' occuring. whenever pyobjc is needed including installing pyobjc

Question

我需要将一些需要安装的软件包导入 python。从命令行 (zsh) 我尝试使用 pip、python 和自制软件（我正在使用 Mac OS Big Sur）但是在需要 pyobjc 时出现错误：“ ValueError：以 10 为底的 int() 的无效文字：''"。这与我在尝试安装 pyobjc 时遇到的错误相同（我尝试过 pip、brew 和下载源代码以及运行 setup.py）。我试过使用 2.7 和 3.9 版的 pip 和 python。我该如何调试呢？我看到错误的结尾：

  File "/usr/local/Cellar/python@3.9/3.9.0_1/Frameworks/Python.framework/Versions/3.9/lib/python3.9/distutils/dist.py", line 985, in run_command
    cmd_obj.run()
  File "/private/var/folders/hf/7khqn6yn0nz3mny8210jr0380000gn/T/pip-install-ropcjbe2/pyobjc-core/setup.py", line 619, in run
    % (tuple(map(int, get_sdk_level(self.sdk_root).split("."))))
ValueError: invalid literal for int() with base 10: ''

我不确定要查看哪个文件才能确定问题出在哪里

经过一些研究，我发现了一些线索可以阐明这个主题。

在this论坛中，有解释安装时出现错误的原因。

...the data it's parsing here is the output of /usr/bin/xcrun -sdk macosx --show-sdk-path. That should return the full SDK path on Xcode 5 and later...

It should return something like /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk. The parsing code takes the last path component (MacOSX10.14.sdk), strips off the first 6 characters (MacOSX) and the last 4 characters (.sdk), which should leave just the version number (10.14), which is split on . and the two parts are cast as integers. In your case, this seems to be empty.

我也是运行宁大苏尔，等我运行/usr/bin/xcrun -sdk macosx --show-sdk-path回来/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk。安装系统删除了 'MacOSX' 和 '.sdk' 以检查版本，然后将空字符串转换为整数似乎是崩溃的原因。

我还查看了 PyObjC 存储库中存在的问题，瞧，这是一个最近的问题：https://github.com/ronaldoussoren/pyobjc/issues/333. As per the developer's comment，即将发布的 PyObjC 版本 7 应该会解决这个问题。
