在Sage中：No模块名为＆＃x27; crypto＆＃x27; - ＆gt; pip的SSL错误

Question

我从此答案

sage --pip install pycrypto

但是，当我尝试此操作时，我会收到以下错误：

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

Answer 1

由于您有Sage 9.2，我建议您升级。

这样做的最佳方法取决于

• 您是要开发Sage还是仅使用它，
• 软件包，则需要

如果您

• 只打算使用Sage
• 只需要PIP可容纳的

安装什么额外的软件包，然后考虑从

• <<<<<<<< a href =“ https://github.com/3-manifolds/sage_macos/releases” rel =“ nofollow noreferrer”> https://github.com/3-manifolds/sage_macos/releases

然后启动Sage，然后在Sage提示下运行

%pip install pycrypto

并类似地用于您需要的任何PIP-INSTALLABLE套件。

然后退出Sage并再次启动。
