與PIP更新和暢達更新蟒蛇更新衝突，和PIP安裝在蟒蛇似乎打破

Question

我剛剛開始與蟒蛇在Ubuntu 12.04。當我嘗試更新下面的說明here我遇到衝突：

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，並將其鏈接到蟒蛇。然後，我繼續更新蟒蛇以及

nikos@nikos-hp:~$ conda update anaconda 

此時我停下來，因爲此更新似乎想鏈接到PIP-1.4.1，這是我剛剛從升級。

當我從這篇文章明白here我應該堅持點子1.4.1，即使暢達警告我升級到1.5。然而，不管我鏈接哪個版本，我得到一個錯誤

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

問題是分佈中的一個錯誤，影響pip。該錯誤消息有點讓人誤解，因爲您剛剛被告知「pip list」發生了錯誤

要解決此問題，您需要刪除分發並安裝setuptools（它將取代分發）。

conda remove distribute 
conda update setuptools 

這些命令應該可以解決這個問題。這將在下一個版本的Anaconda中修復。
