I updated the mac to Mountain Lion (10.8) and now the project I developed with Python and Google App Engine does not work.
GAE libraries are found, while standard Python
I just ran into the same problem, picked a new version (mercurial-2.2.3+20120707-py2.7-macosx10.7) from the Mercurial website and now it works again.
I had this same issue.
Reinstalling Mercurial fixed it. Get it from here: http://mercurial.berkwood.com/
I had a similar problem to this last night after upgrading to OX 10.9 Mavericks. I had tried
brew install hg
and brew update
but they didn't work, as everyone's systems are different if you're running homebrew I would recommend running
brew doctor
to see what your particular issue is, in my case I had the following;
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on those kegs to fail to run properly once built. Run
brew link
on these: mercurial
So to fix my mercurial issue I ran;
brew link --overwrite mercurial
On OS X - 10.8.2 Installing mercurial through Python easy_install tool solved the problem
easy_install -U mercurial
