python - "pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available"

Question

我有 anaconda 包并运行 Spyder。这是我的系统信息:

anaconda                  2018.12                  py37_0

Python                    3.7.1

pip                       18.1

Dell Inspiron 13 7000 64-bit

我无法在命令提示符下使用 pip 安装任何东西。例如，我在尝试安装 numpy 时得到以下信息(我已经通过 anaconda 安装了):

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

Requirement already satisfied: numpy in c:\users\uday rallabhandi\anaconda3\lib\site-packages (1.15.4)

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

Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

请帮助我理解为什么会这样。

这是我使用 Anaconda 在 Windows 10 上纠正错误的过程:

1. 在我的环境变量中添加了以下路径:
   • /AppData/Local/Continuum/Anaconda3
   • /AppData/Local/Continuum/Anaconda3/Scripts
   • /AppData/Local/Continuum/Anaconda3/Library
   • /AppData/Local/Continuum/Anaconda3/Library/Bin

在这个阶段，错误信息仍然存在。

1. 我从 Anaconda Prompt 安装了最新版本的 pip:

   python -m pip install --upgrade pip

这似乎更正了 DLL 冲突。
