Question

我刚开始使用Ubuntu 12.04上的anaconda。当我按照说明here尝试更新时，我发生冲突：

nikos@nikos-hp:~$ conda update conda
# All packages already at latest version, nothing to do.
# packages in environment at /home/nikos/anaconda:
#
# 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 /home/nikos/anaconda)

conda                     2.3.1                    py27_0

所以我更新了pip

nikos@nikos-hp:~$ conda update pip -p /home/nikos/anaconda

更新到pip-1.5，并将其链接到anaconda。然后我继续更新anaconda

nikos@nikos-hp:~$ conda update anaconda

此时我停止了，因为此更新似乎想要链接回pip-1.4.1，我刚刚升级了。

据我所知here我应该坚持使用pip 1.4.1，即使conda警告我升级到1.5。但是，无论我链接哪个版本，我都会收到错误

nikos@nikos-hp:~/anaconda/bin$ ./pip list
apptools (4.2.0)
astropy (0.2.5)
atom (0.3.4)
.

scikit-learn (0.14.1)
scipy (0.13.0)

问题是影响pip的分发错误。错误消息有点误导，因为您只是被告知“pip list”发生错误

要解决此问题，您需要删除分发，然后安装setuptools（取代分发）。

conda remove distribute
conda update setuptools

这些命令应解决问题。这将在下一版Anaconda中修复。

Anaconda更新与pip更新和conda更新冲突，并且安装在anaconda中的pip似乎已损坏
