PIP不會升級包

Question

我已經安裝numpy的以下版本：

sh-3.2# pip --version 
pip 1.5.4 from /usr/local/lib/python2.7/site-packages (python 2.7) 

sh-3.2# pip list 
... 
numpy (1.7.1) 
... 

sh-3.2# pip install --upgrade --ignore-installed numpy 
Downloading/unpacking numpy 
    Downloading numpy-1.8.0.tar.gz (3.8MB): 3.8MB downloaded 
    Running setup.py (path:/private/tmp/pip_build_root/numpy/setup.py) egg_info for package numpy 
    Running from numpy source directory. 

...installing stuff.. 

Successfully installed numpy 
Cleaning up... 
sh-3.2# pip list 
... 
numpy (1.7.1) 
... 

正如你可以看到：沒有升級。那個怎麼樣？

UPDATE2：安裝過程的完整輸出其實我覺得路徑應該沒關係：

sh-3.2# which pip 
/usr/local/bin/pip 
sh-3.2# ls -l /usr/local/bin/pip 
lrwxr-xr-x 1 Tom admin 30 15 Jun 2013 /usr/local/bin/pip -> ../Cellar/python/2.7.5/bin/pip 
sh-3.2# which python 
/usr/local/bin/python 
sh-3.2# ls -l /usr/local/bin/python 
lrwxr-xr-x 1 Tom admin 33 15 Jun 2013 /usr/local/bin/python -> ../Cellar/python/2.7.5/bin/python 
sh-3.2# pip --version 
pip 1.5.4 from /usr/local/lib/python2.7/site-packages (python 2.7)

Answer 1

您的pip命令顯示python從/usr/local/lib/python2.7, 而在安裝過程中它是/usr/local/Cellar/python/2.7.5/

它是符號鏈接還是不同的路徑？

Answer 2

好的，問題是，舊的軟件包被保存了。因此，我只需進入directoy並移除相應的包裝。

這裏是我做過什麼：

sh-3.2# pip list | grep numpy 
numpy (1.7.1) 
sh-3.2# pwd 
/usr/local/lib/python2.7/site-packages 
sh-3.2# rm numpy* 
sh-3.2# pip install numpy 
sh-3.2# pip list | grep numpy 
numpy (1.8.0) 

現在它工作正常！
