我用make安裝不altinstall兩個Python版本衝突在Ubuntu 11.10解夢問題：導入錯誤：沒有模塊
以前現在，當我運行python它給它2.7.2+
Python安裝2.7.5
ImportError: cannot import name MAXREPEAT
我知道這裏已經有條目了。但是我沒有安裝virtualenv，我也沒有安裝過。如果我運行python2.7 它運行完美。 現在，當我試圖導入一個類似mysqldb的庫時，它說該模塊不存在。 我在安裝python2.7之前安裝了它。
解決方案是什麼？我應該卸載整個python，或者我應該如何卸載python2.7.5或者我應該保留它？如果我保留，那我怎樣才能導入這些模塊？

會重新安裝該解決獲取和運行默認的問題2.7.2+在Ubuntu回來？：https://launchpad.net/ubuntu/oneiric/+source/python-defaults/2.7.2-7ubuntu2
*此前更新*
現在我可以從bash運行python
這裏是新問題。而且我使用pip安裝每個模塊。從LIB
現有模塊可以進口，但新安裝的人是不能忽視的：

>>> import requests
Traceback (most recent call last):

檢查它是在本地運行的Python，版本衝突問題後：

me:~$ sudo which python2.7
/usr/local/bin/python2.7
me:~$ which python2.7

，我認爲它的運行一樣。然後..
me:/usr/local/bin$ dir python2.7
python2.7
me:/usr/local/bin$ cd /usr/bin
me:/usr/bin$ dir python2.7
python2.7
me:/bin$ cd /usr/bin
me:/usr/bin$ dir python
python
me:/usr/local/bin$ dir python
python
me:/usr/local/bin$ dir python2.7
python2.7
還要檢查以下內容：
~$ which pip
/usr/local/bin/pip
好了，現在我安裝的virtualenv ，這是我做過什麼
(foldername)[email protected]:~/caller$ sudo pip install requests
Requirement already satisfied (use --upgrade to upgrade): requests in /usr/local/lib/python2.7/dist-packages

，現在我們可以看到，2.7.2 +又回來了！那麼現在發生了什麼？ 有什麼問題？
不推薦從linux卸載較舊的python。那麼我怎麼能用2.7.5運行virtualenv而不是2.7.2+？
的就像我說的做安裝是我做的。在那之前你已經說過所有的步驟。是的，但我沒有使用--path = XXX或/ usr，我擔心是什麼導致它駐留在python旁邊。現在有python和python2.7 – user2290820
在shell中運行'python'後立即得到它嗎？ –
確定現在有一個update.python正在運行，但問題是與導入modules.check更新主要問題 – user2290820
