与PIP更新和畅达更新蟒蛇更新冲突，和PIP安装在蟒蛇似乎打破

Question

我刚刚开始与蟒蛇在Ubuntu 12.04。当我尝试更新下面的说明here我遇到冲突：

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PIP

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

哪些更新PIP-1.5，并将其链接到蟒蛇。然后，我继续更新蟒蛇以及

nikos@nikos-hp:~$ conda update anaconda 

此时我停下来，因为此更新似乎想链接到PIP-1.4.1，这是我刚刚从升级。

当我从这篇文章明白here我应该坚持点子1.4.1，即使畅达警告我升级到1.5。然而，不管我链接哪个版本，我得到一个错误

nikos@nikos-hp:~/anaconda/bin$ ./pip list

问题是分布中的一个错误，影响pip。该错误消息有点让人误解，因为您刚刚被告知“pip list”发生了错误

要解决此问题，您需要删除分发并安装setuptools（它将取代分发）。

conda remove distribute 
conda update setuptools 

这些命令应该可以解决这个问题。这将在下一个版本的Anaconda中修复。
