Hi Fabian,
I see you have a too old pip version. Sorry for not giving you a
faster reply, but just do:
$ pip install --upgrade pip
And you will get the latest version from PyPI (0.8.1 by now).
I tried to install the package you did, and it worked here.

Just update it!

Hi,
I am using pip version 0.3.1 on Ubuntu Linux 9.10 to install django-piston in a virtualenv.
Since I need a specific version of django-piston I have the following entry in the requirements.txt file:
-e hg+http://bitbucket.org/jespern/django-piston@dc0ee00d3bfc#egg=django-piston
The first time the install works fine with pip but on the second time I get the following error:
Command hg fetch -q failed with error code 255 Exception information: Traceback (most recent call last): File "/usr/lib/python2.6/dist-packages/pip.py", line 252, in main self.run(options, args) File "/usr/lib/python2.6/dist-packages/pip.py", line 408, in run requirement_set.install_files(finder, force_root_egg_info=self.bundle) File "/usr/lib/python2.6/dist-packages/pip.py", line 1741, in install_files req_to_install.update_editable() File "/usr/lib/python2.6/dist-packages/pip.py", line 1486, in update_editable version_control(self.url).obtain(self.source_dir) File "/usr/lib/python2.6/dist-packages/pip.py", line 2942, in obtain call_subprocess(['hg', 'fetch', '-q'], cwd=dest) File "/usr/lib/python2.6/dist-packages/pip.py", line 3543, in call_subprocess % (command_desc, proc.returncode)) InstallationError: Command hg fetch -q failed with error code 255
If I run "hg fetch -q" manually in the django-piston repository I get:
abort: working dir not at branch tip (use "hg update" to check out branch tip)
mercurial is at version 1.3.1.
Any ideas what is wrong and how I get it to work?
Thanks a lot, Fabian
