無法在Mac OS X中的優勝美地升級6

Question

我想在我的Mac TensorFlow升級六點，我所做的：

sudo pip install --ignore-installed six 

我也得到：

The directory '/Users/lingxiao/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Successfully installed six-1.10.0 

的一點是，它以成功安裝結束。但是，當我進入IPython的解釋做：

import six 
six.__version__ 

我仍然看到1.4.1。解決辦法是什麼？

Answer 1

使用-U or --upgrade升級包：

sudo pip install --upgrade six 

---

選項1：

在IPython中：

import pip 

def install(package): 
    pip.main(['install', package]) 

install('six') 

選項2：

在IPython中：

import sys 
sys.path 

然後查看安裝的IPython的包在哪裏。它應該看起來像這樣：

'/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/site-packages/six-1.4.1 blah blah' 

在您的終端python中執行相同的操作以找到您安裝新的六個軟件包的位置。然後將這個較新的六個軟件包複製到ipython site-packages目錄中（將six-1.4.1軟件包先移到另一個目錄中以防萬一）。

之後，註冊新的封裝成IPython中：

# use your six located in your ipython path 
six_path = '/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/six-1.10.0 blahblah' 
sys.path.append(six_path) 

然後你就可以

import six 

IPython中應重啓保持較新的6包的軌道。
