pip install pyzmail ERROR message

问题

I use Python 3.5.2. I installed imapclient with no problem pip install imapclient. However when I tried to install pyzmail, pip install pyzmail, I received error message below:

    ImportError: No module named '_markerlib'
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\J

I had the same problem, and resolved it using: easy_install pyzmail

回答2:

To those who find this thread and have switched to Python 3.6, this pyzmail fork enabling pip install on Python 3.6 worked very well for me :

 pip install pyzmail36

回答3:

I just had this issue and solved it this way: type pip install setuptools==20.1.1, then try pip install pyzmail again. I had the latest version of setuptools (version 34.something) and it seems this version gets buggy when installing pyzmail.

回答4:

use pip install pyzmail36

This claims to be "a fork which is meant to be pip installable on python 3.6+".
