在Cygwin中永久设置Anaconda的Python路径 [英] Permanently set Python path for Anaconda within Cygwin

问题描述

我想在我的Windows 7机器上安装Anaconda。我经常使用cygwin来做我的命令行工作，我想从那里管理Anaconda。我已经通过图形安装程序没有任何问题，并检查必要的框，重置我的默认路径这个安装的python。我去检查python是在哪里，最初我得到这个...

  $ which python 
 / usr / bin / python 
  

从这里python工作正常...

  $ python 
 Python 2.7.5（默认，2013年10月2日，22:34:09）
 [GCC 4.8.1] on cygwin

但我想从anaconda工作，所以我只需要重新定义我的路径。 。

  $ export PATH = / cygdrive / c / anaconda：$ PATH 
 $ which python 
 / cygdrive / c / anaconda / python 
  

现在我应该好了，进入python，它只是挂起

  $ python 
  

任何想法为什么会发生这种情况？ verbose return，below ...

可能相关）问题我有需要重置路径每次我关闭/打开cygwin。我输入以下文本到.bashrc和.profile尝试并永久设置路径：

 ＃设置路径到python从anaconda安装
 export PATH = / cygdrive / c / anaconda：$ PATH 
  

并关闭cygwin，我回到：

  $ which python 
 / usr / bin / python 
  
 
 
 
这可能与设置某些系统环境变量有关吗？
解决方案
要使用Cygwin中的交互式Python shell，我使用-i选项。
 
 
 
要从Anaconda安装，使用上面建议的步骤：
  $ export PATH = / cygdrive / c / anaconda：$ PATH 
 $ which python 
 / cygdrive / c / anaconda / python 
  
然后我在Cygwin中启动python  - i选项：
  $ python -i

库也工作正常。例如，现在可以导入pandas库（已通过Anaconda安装）。
 >>> import pandas 
>>>>> pandas.DataFrame 
< class'pandas.core.frame.DataFrame'> 
 
现在为了使这个永久性，我在我的bashrc文件中添加了路径：
  $ echo'export PATH = / cygdrive / c / anaconda：$ PATH'>> .bashrc 
 $ source .bashrc 
 $ which python 
 / cygdrive / c / anaconda / python 
  
我希望这有助于。
 
I'm trying to install Anaconda on my Windows 7 machine. I often use cygwin to for my command-line work, and I would like to manage Anaconda from there. I've worked through the graphic installer without any issues, and checked necessary boxes to reset my default path to this install of python. I go ahead to check where python is and initially I get this...
$ which python
/usr/bin/python
From here python works fine...
$ python
Python 2.7.5 (default, Oct  2 2013, 22:34:09)
[GCC 4.8.1] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
But I'm trying to work from anaconda, so I should just need to redefine my path...
$ export PATH=/cygdrive/c/anaconda:$PATH
$ which python
/cygdrive/c/anaconda/python
And now I should be good to go, but when I try and step into python, it just hangs
$ python
Any idea why this might be happening? verbose return, below...

Another (possibly related) issue I'm having is needing to reset the path every time I close/open cygwin. I've entered the following text into .bashrc and .profile to try and set the path permanently:
# Set path to python from anaconda install
export PATH=/cygdrive/c/anaconda:$PATH
After opening and closing cygwin, I return to:
$ which python
/usr/bin/python
Could this be related to setting certain system environment variables?
解决方案
To work with the interactive Python shell in Cygwin I use the -i option.

To get it from the Anaconda install, I used the steps suggested above:
$ export PATH=/cygdrive/c/anaconda:$PATH
$ which python
/cygdrive/c/anaconda/python
Then I launch python within Cygwin with the -i option:
$ python -i

>>>>
The libraries are also working fine. For instance the pandas library (which has been installed through Anaconda) can be imported now.
>>>> import pandas
>>>> pandas.DataFrame
<class 'pandas.core.frame.DataFrame'>
Now to make this permanent I added the path in my bashrc file:
$ echo 'export PATH=/cygdrive/c/anaconda:$PATH' >> .bashrc
$ source .bashrc
$ which python
/cygdrive/c/anaconda/python
I hope this helps.
