正在安装 python 软件包 'processing'

Question

我是 python 和 pycharm 的新手，在安装 processing 软件包时遇到错误。其他软件包已成功安装。我一直在使用 PyCharm 的软件包安装程序。但是，当我在命令行键入 pip install processing 时，我也会收到错误消息。我的 PyCharm 版本是 2022.1。 PyCharm 的命令输出是：

Collecting processing

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

Ã— Encountered error while generating package metadata.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.
WARNING: You are using pip version 22.0.3; however, version 22.0.4 is available.
You should consider upgrading via the 'C:\Program Files\QGIS 3.22.5\bin\python.exe -m pip install --upgrade pip' command.

Answer 1

那个包已经有 14 年历史了 – 它是 2008 年的 – 而且它只有 Python 2。

你不能在 Python 3 上安装它，这是你（或你的 QGIS）运行。

很可能您也不应该尝试安装它。
