ContextualVersionConflict: (PyYAML 5.3.1 (/usr/lib/python3/dist-packages), Requirement.parse('pyyaml>=5.4.1'), {'kube.netes'})

Question

`我正在嘗試在我的 Ubuntu v20 系統上安裝 tutor。 我瀏覽了文檔並安裝了所有先決條件，例如 Docker、docker 並啟動了代理 web 服務器，如文檔中所述。 當我嘗試在本地運行 tutor 時收到以下消息

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 584, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 901, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 792, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (PyYAML 5.3.1 (/usr/lib/python3/dist-packages), Requirement.parse('pyyaml>=5.4.1'), {'kubernetes'})

During handling of the above exception, another exception occurred:

它告訴您需要 PyYAML 版本 5.4.1 及更高版本，而您有 5.3.1。

嘗試安裝pyyaml>=5.4.1 ：

!pip install pyyaml>=5.4.1
