Hi all,
Owen and I were trying out virtualenv + easy_install on pygr today and
ran into some problems with easy_install. One problem is to be
expected and can be ignored; the other is a bug with easy_install that
only minorly affects us. They are placed in this e-mail for posterity,
not for fixing!
So, when using
easy_install /path/to/some/git/clone
you find:
--
Problem #1 -- you need to have Pyrex installed, because the git repo
doesn't contain the generated C files. Duh. OK, fine.
There are a couple of ways to try to fix this, but all of them introduce
the step of requiring
--
Problem #2: there an odd metaclass error,
...
File "build/bdist.linux-i686/egg/setuptools/sandbox.py", line 63, in run
File "build/bdist.linux-i686/egg/setuptools/sandbox.py", line 29, in <lambda>
File "/Users/t/dev/pygr/setup.py", line 26, in <module>
import pygr
File "/private/tmp/pygr/pygr/__init__.py", line 7, in <module>
import metabase
File "/private/tmp/pygr/pygr/metabase.py", line 7, in <module>
from coordinator import XMLRPCServerBase
File "/private/tmp/pygr/pygr/coordinator.py", line 930, in <module>
class ResourceFile(file):
TypeError: Error when calling the metaclass bases
first argument must be callable
that seems to come from subclassing 'file'. I haven't isolated the
error yet, but changing 'file' to 'object' does avoid it (while breaking
ResourceFile, presumably -- not a fix, just a note ;).
You can still, however, build an egg with 'bdist_egg' and then
easy_install *that*.
--
The upshot is: let's make sure to distribute eggs and place them in the
right place; otherwise people are going to have a tough time using
easy_install to install pygr.
cheers,
