我尝试从 pip 安装并不断收到类似类型的错误。

$ pip install quandl
Traceback (most recent call last):
File "/usr/bin/pip", line 9, in <module>
load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()

if _lib.Cryptography_HAS_SSL_ST:
AttributeError: 'module' object has no attribute 'Cryptography_HAS_SSL_ST'

现在,即使我尝试安装不同的 pip 模块,我也遇到了同样的错误。有什么解决方案吗?这是由于在下载 pip 模块时进程意外终止所致。

请帮助我完成纠正此错误的必要步骤。

我尝试安装这个

$ pip install -U cryptography

load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()

最佳答案

这里是 Ubuntu 16.04.3:

我想我已经通过删除 python-openssl 包(及其依赖项)解决了这个问题:

apt-get --auto-remove remove python-openssl

然后用 pip 安装最新版本:

pip install pyOpenSSL

当然,如果你安装另一个依赖它的 apt 包,它会将它拉回来。我希望你从现在开始使用 pip 代替 apt 来做所有事情,应该没问题。

编辑:截至 2019 年 1 月,此问题似乎不再存在。
