Certbot won't launch in El Capitan

[CyborgSam]

I installed brew following the directions on their home page. Then I installed certbot.

certbot crashes, with or without any parameters (e.g. certbot --help crashes). I tried three different El Capitan installs, one was clean installed after the first certbot crash to be sure there was a clean slate. All have the latest updates.

The beginning of the error in Terminal is:
Traceback (most recent call last):
File “/usr/local/bin/certbot”, line 11, in
load_entry_point(‘certbot==0.10.0’, ‘console_scripts’, ‘certbot’)()
File “/usr/local/Cellar/certbot/0.10.0/libexec/lib/python2.7/site-packages/pkg_resources/init.py”, line 561, in load_entry_point
return get_distribution(dist).load_entry_point(group, name)

Is this a certbot problem or a brew problem?

Never mind. I saw the 6 hour old Git release of 0.10.1 & used pip to install it. All is working!

Many thanks to the community for certbot & Let’s Encrypt.

This traceback looks truncated - can you provide the full traceback?

Historically we used to have some issues running on OS X. I’m not sure if those have been resolved, but a look at the traceback may help evaluate.

We must have posted at nearly the same time. Updating to 0.10.1 cured it for me.

Here’s the complete traceback:
