我有anaconda软件包并运行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

我无法从命令提示符下使用pip安装任何内容。例如，在尝试安装numpy时（通过anaconda已经拥有），我得到以下信息：

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)

假设我在 Python 中运行了这段代码：

 while True:
     try:
         anything that doesn't break loop
     except: pass

我怎样才能让它停止呢？（注意：我怀疑这不是我应该通过测试来学习的时候）。

当然，实际上我会使用一个break声明。这是一个理论问题；即使传递了一个 KeyboardInterrupt，又如何打破这个循环呢？
