使用pip在ubuntu上安装prettytable时出错

Question

我刚刚安装了pip，安装了几个包np。 我试过这个

pip install prettytable
Collecting prettytable
From cffi callback <function _verify_callback at 0x7f424837d6e0>:
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/OpenSSL/SSL.py", line 313, in wrapper
    _lib.X509_up_ref(x509)
AttributeError: 'module' object has no attribute 'X509_up_ref'
  Could not find a version that satisfies the requirement prettytable (from versions: )
No matching distribution found for prettytable

我如何安装漂亮的？

Answer 1

错误来自PyOpenSSL 。 您的OpenSSL太旧或太新。 尝试升级或降级OpenSSL和PyOpenSSL 。

Answer 2

重新安装 pyopenssl 对我有用：

pip uninstall pyopenssl
pip install pyopenssl
