尝试在 Cygwin 中进行 pip 安装失败：“用户警告：发现未处理的 git 存档（未应用导出子程序）”

Question

我正在尝试在运行 Windows 10 的 X86_64 计算机上的 Cygwin 上安装一些 Python 包。

我刚刚更新了我的 Cygwin 发行版，并安装了 python。现在，使用 pip，某些软件包可以正常安装，例如

argparse

，但有些软件包却不能。错误似乎是：

• UserWarning: git archive did not support describe output

• UserWarning: unprocessed git archival found (no export subst applied)

请参阅下面的完整跟踪。

为什么会出现这种情况？我该如何解决/规避这个问题？

      Problem with the CMake installation, aborting build. CMake executable is cmake

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

有关我的设置的更多信息：

• 24.2 点
• Python 3.9.16
• 将根据要求提供更多信息...

相关问题：

• 我无法安装任何库，它给我一个错误，说 subprocess-exited-with-error

  建议的解决方案在哪里

  设置完整的Python版本

  $ sudo apt install python3-full

  ...但是没有这样的Cgwin包。我已经安装了更多我认为可能与 br 相关的 Python 软件包，但没有成功。

Answer 1

您需要安装 Cygwin 软件包

cmake

、

make

和

ninja

。

cmake

本身是不够的；可能仅仅

ninja

就足够了。但他们三个一起就可以了。

感谢@Philippe指出了这条途径。
