Problems with using pip

Make sure your pip command uses python 2.6-2.7. Some distributions now use python 3.x as a default and FlexGet does not work with that. Python 2.6-2.7 pip may be available under pip2.7 or other means. If you receive traceback that mentions python3.x you're using wrong pip. To verify which version pip is using you can use:

pip --version

If this crashes you will need to reinstall pip. Try to remove pip from operating system package manager if possible. You could also run which pip and delete the script. Open fresh shell and verify that python -V reports 2.6-2.7. Continue with pip install.

Default python version switched

[root@foobar ~]# pip install --upgrade flexget
Traceback (most recent call last):
  File "/usr/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3.2/site-packages/pkg_resources.py", line 2736, in <module>
    working_set.require(__requires__)
  File "/usr/lib/python3.2/site-packages/pkg_resources.py", line 690, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3.2/site-packages/pkg_resources.py", line 588, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==1.2.1

This is most likely because operating system has changed from using python 2.7 to 3.2. Pip was installed on 2.7 but now that the script is ran it uses default python which is 3.2. You will need to re-install pip for python 2.7. This can happen for any python executable, including FlexGet if the operating system changes default python version. Re-installing the packages with correct python version will resolve the issue.

Command not found

If for some reason the flexget executable is not in place even after installing with pip you may get error like.

$ flexget -v
-bash: flexget: command not found

It might be resolvable by running

pip install --upgrade --force-reinstall flexget

Setup tools may need to be updated as well, might need to run this command before the previous one.

curl https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py | sudo python

A plugin with the same name is already registered

For some reason the pip leaves files hanging from older version sometimes. If you encounter this it's best to do is update pip and do some cleanup.

Upgrade pip with

pip install --upgrade pip

We need to know where FlexGet installation is in the filesystem, as this differs per operating system easiest way is to run following command.

python -c 'import flexget; print flexget.__file__'

Which will print something along

/usr/lib/python2.7/site-packages/flexget/

Next uninstall FlexGet

pip uninstall flexget

If you still have the printed directory left, delete it. This should get rid of any extra files hanging around. Next step, reinstall FlexGet.

pip install flexget

ImportError: cannot import name IncompleteRead

This is caused by a bug in Ubuntu's pip package. You'll need to uninstall pip with apt, then install with the instructions here.
