I't's a bug in pip. The file in question is opened by pip a few lines
above. The particular code path is called because the else
logger.warn() clause gets triggered (i.e. where it says "## FIX ME"
:) )
f = open(record_filename)
for line in f:
line = line.strip()
if line.endswith('.egg-info'):
egg_info_dir = prepend_root(line)
break
else:
logger.warn('Could not find .egg-info directory in
install record for %s' % self)
## FIXME: put the record somewhere
## FIXME: should this be an error?
return
f.close()
new_lines = []
f = open(record_filename)
for line in f:
filename = line.strip()
if os.path.isdir(filename):
filename += os.path.sep
new_lines.append(make_path_relative(prepend_root(filename),
egg_info_dir))
f.close()
f = open(os.path.join(egg_info_dir, 'installed-files.txt'), 'w')
f.write('\n'.join(new_lines)+'\n')
f.close()
finally:
if os.path.exists(record_filename):
os.remove(record_filename)
os.rmdir(temp_location)
The error comes from the os.remove line 2nd from bottom. The file was
opened in the top line. The logger.warn code path returns without
closing the file. If I add f.close() just before return then I get:
$ pip install bento
Downloading/unpacking bento
Downloading bento-0.1.1.tar.gz (582kB): 582kB downloaded
Running setup.py egg_info for package bento
Installing collected packages: bento
Running setup.py install for bento
Could not find .egg-info directory in install record for bento
Successfully installed bento
Cleaning up...
It's probably better to use the with statement though.
