问题
I am in a bind. Conda keeps telling me to upgrade pip, however, when I run the conda update pip command, it says pip is fully updated. My exact terminal output is below:
Anton-MacBook-Pro:~ anton$ conda update pip -p /Users/anton/anaconda/envs/py3k
# All packages already at latest version, nothing to do.
# packages in environment at /Users/anton/anaconda/envs/py3k:
#
# Warning: Your version of pip is older than what conda requires for pip
# integration, so pip-installed packages will not be displayed. Please
# update pip, (conda update pip -p /Users/anton/anaconda/envs/py3k)
pip 1.4.1 py33_1
Anton-MacBook-Pro:~ anton$
My interpretation of the terminal output is:
- Me telling conda to update pip.
- Conda telling me pip is up to date, then,
- Conda warning me that pip is not up to date and that I should run the exact code I just ran in step 1.
回答1:
This is a conda bug, as Jacob Budin noted. Try running
conda update distribute
and see if that makes the problem go away. Either way, you don't need to worry about it.

As of this writing, pip v1.4.1 is the latest stable release. The warning you're encountering is a known bug in conda (pydata/conda #429).
Check to see if running ./python ./pip list in the bin/ directory of your conda environment (i.e., using the local Python and pip scripts) produces the output you'd expect (that is, a list of installed packages, without errors); if not, that what it's getting hung up on.
I'd add your experience to the GitHub bug thread.
