I just installed pip, installed a few packages np. I tried this
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
How do I install prettytable?
The error comes from PyOpenSSL
. Either your OpenSSL
is too old or too new. Try upgrading or downgrading OpenSSL
and PyOpenSSL
.
Reinstalling pyopenssl worked for me:
pip uninstall pyopenssl
pip install pyopenssl
