Mac OS Python 3.6 无法通过 pip 安装任何包(TLS/SSL 证书)

KM.*_*KM. 5 macos pip python-3.x python-3.6

我使用的是 Mac OS 10.15.2 (Catalina)。预装了 Python 2 和 3.7 ( /usr/bin/python, /usr/bin/python3),我已经用 brew ( /usr/local/bin/python3)安装了 Python 3.6 。另外,我正在使用虚拟环境,如下所示:

  1. virtualenv -p <dir_python> venv (创建 venv)
  2. source venv/bin/activate (激活venv)
  3. pip install <package> (安装软件包)

当我使用 Python 2 和 3.7 创建虚拟环境时,一切正常。每当我使用 Python 3.6 时,我都无法安装任何东西。例如,使用“numpy”,我得到以下信息:

WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

WARNING: 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 for four more times ...  

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

ERROR: Could not find a version that satisfies the requirement numpy (from versions: none)

ERROR: No matching distribution found for numpy

我已经尝试了其他帖子中的一些内容,这些内容描述了看似相似的内容,但以下内容均没有帮助,例如:

  • 卸载并重新安装 Python 3.6
  • pip install --upgrade pip --trusted-host pypi.org --trusted-host files.pythonhosted.org pip setuptools

任何帮助深表感谢!谢谢。

我也遇到过同样的问题。

为了解决这个问题,我刚刚使用brew更新了python。

brew upgrade python3
