Pymacs, ropemacs, virtualenv
http://
pymacs, ropemacs, and virtualenv, all at the same time.
Posted on March 4, 2011 by slacy
So, you’re developing for Python, and you want to use rope and ropemacs and pymacs, but it’s totally busted when you use your virtualenv.
In addition, the packaged versions of pymacs+ropemacs for ubuntu 10.10 (and 11.04) are also kind of busted, because they complains with really odd errors.
Here’s the solution:
Install the latest, greatest versions of everything into your virtualenv:
. ./env/bin/activate
pip install -e hg+https:/
pip install -e hg+https:/
pip install -e hg+https:/
pip install -e git+https:/
Unfortunately, pymacs doesn’t cleanly install, so then need to:
cd env/src/pymacs
make
Once that’s done, you should have env/src/

Hi François,
what about the following:
I'll fork Pymacs on Github into another PDEE branch, lets assume
https:/
afterwards copy the python-mode files in pymacs, the branch name
than it's yours to raise "make" out from Pymacs and turning it into a general make, prepared to deal with a lot of more stuff to come.
Agreed?
Andreas
