激活 conda 环境后是否必须激活 venv 才能使 pip 正常工作？

Question

我不确定这是否只是巧合，但昨天在重新启动并运行 Windows 升级后，我收到了 pip 的 SSL 模块错误。 我使用 Anaconda3 以及我的所有虚拟环境接收我的系统 Python。 我卸载并重新安装了 Anaconda，那里的事情似乎运行良好。 但是，我发现让我的虚拟环境正常运行的唯一方法是首先激活我的 conda 环境，然后在此基础上激活虚拟环境。 我以前不必这样做。 这是预期的行为吗？

例如，

(base) python -m venv .venv
conda deactivate
.venv\Scripts\activate
(.venv) pip install numpy

追溯：

  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/numpy/
  Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/numpy/
  Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/numpy/
  Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/numpy/
  Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/numpy/
  Could not fetch URL https://pypi.org/simple/numpy/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/numpy/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

但是，如果我这样做

(base) python -m venv .venv
(base) .venv\Scripts\activate
(.venv) (base) pip install numpy
(.venv) (base) pip freeze
numpy==1.18.1

然后一切正常。 这让我花了很长时间才弄清楚，我仍然不一定明白为什么我会出现这种行为。 有人可以帮助启发我吗？
