Latest 'pip' fails with "requires setuptools >= 0.8 for dist-info"

Question

Using the recent (1.5) version of pip, I get an error when attempting to update several packages. For example, sudo pip install -U pytz results in failure with:

Wheel installs require setuptools >= 0.8 for dist-info support.
pip's wheel support requires setuptools >= 0.8 for dist-info support.

I don't understand this message (I have setuptools 2.1) or what to do about it.

Exception information from the log for this error:

Solution 1

This worked for me:

sudo pip install setuptools --no-use-wheel --upgrade

Note it's usage of sudo

UPDATE

On Windows you just need to execute pip install setuptools --no-use-wheel --upgrade as an administrator. In Unix/Linux, the sudo command is for elevating permissions.

UPDATE 2

This appears to have been fixed in 1.5.1.

Solution 2

First, you should never run 'sudo pip'.

If possible you should use your system package manager because it uses GPG signatures to ensure you're not running malicious code.

Otherwise, try upgrading setuptools:

easy_install -U setuptools

Alternatively, try:

pip install --user <somepackage>

This is of course for "global" packages. You should ideally be using virtualenvs.

Sorry that doesn't seem to completely solve my problem, still working on it.

I had to revert using pip 1.4 for now, will look for a fix later.

Worked for me. No idea why this happened.

Note that the added --no-use-wheel option simply skips use of 'wheel archives', but otherwise preforms exactly the same install as a command that omits it.

Worked for me on Centos 6. Talk about an abstract error message.

[mafrosis]

I would like to add that from within my virtualenv, the use of sudo caused this to not work. Dropping the sudo meant it ran with my newly install pip v1.5 (which has the --no-use-wheel flag)

Worked for me in Raspbian! :)

Oh! I just need to execute as administrator on windows. pip install setuptools --no-use-wheel --upgrade

[orome]

@iSid: Yes, that's the trick. All the extra --no-use-wheel flag does is skip archives. The process works, and will do exactly what it would otherwise do, so no worries. It should work on any platform.

Generally, running pip as sudo is the wrong thing. However, sometimes you do need to install things into system python (such as virtualenv, or pip itself), and sudo is appropriate then.

[orome]

@LukeSneeringer: Why is it "wrong". I don't think I really have a choice, without some major reconfiguration.

[IsmailS]

yeah! I asked that because, there is no sudo command in windows and I didn't knew that it is just to elevate the permissions.

easy_install -U setuptools rocks!
