无法在Mac OS X中的优胜美地升级6

Question

我想在我的Mac TensorFlow升级六点，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 

的一点是，它以成功安装结束。但是，当我进入IPython的解释做：

import six 
six.__version__ 

我仍然看到1.4.1。解决办法是什么？

Answer 1

使用-U or --upgrade升级包：

sudo pip install --upgrade six 

---

选项1：

在IPython中：

import pip 

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

install('six') 

选项2：

在IPython中：

import sys 
sys.path 

然后查看安装的IPython的包在哪里。它应该看起来像这样：

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

在您的终端python中执行相同的操作以找到您安装新的六个软件包的位置。然后将这个较新的六个软件包复制到ipython site-packages目录中（将six-1.4.1软件包先移到另一个目录中以防万一）。

之后，注册新的封装成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) 

然后你就可以

import six 

IPython中应重启保持较新的6包的轨道。
