問題描述
我正在嘗試在我的 Windows 7 機器上安裝 Anaconda.我經常使用 cygwin 來進行命令行工作，我想從那里管理 Anaconda.我已經完成了圖形安裝程序，沒有任何問題，并選中了必要的框以將我的默認路徑重置為此 python 安裝.我繼續檢查 python 在哪里，最初我得到了這個......
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
從這里 python 工作正常...
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.
但我正在嘗試從 anaconda 工作，所以我只需要重新定義我的路徑...
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
現在我應該很好了，但是當我嘗試進入 python 時，它只是掛起
And now I should be good to go, but when I try and step into python, it just hangs
$ python
知道為什么會發生這種情況嗎?詳細返回，下面...
Any idea why this might be happening? verbose return, below...

我遇到的另一個(可能相關的)問題是每次關閉/打開 cygwin 時都需要重置路徑.我在 .bashrc 和 .profile 中輸入了以下文本，以嘗試永久設置路徑:
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
打開和關閉cygwin后，返回:
After opening and closing cygwin, I return to:
$ which python
/usr/bin/python
這可能與設置某些系統環境變量有關嗎?
Could this be related to setting certain system environment variables?
推薦答案
為了在 Cygwin 中使用交互式 Python shell，我使用了 -i 選項.
To work with the interactive Python shell in Cygwin I use the -i option.
為了從 Anaconda 安裝中獲取它，我使用了上面建議的步驟:
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
然后我在 Cygwin 中使用 -i 選項啟動 python:
Then I launch python within Cygwin with the -i option:
$ python -i

這些庫也運行良好.例如，現在可以導入 pandas 庫(已通過 Anaconda 安裝).
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'>
現在為了永久保存，我在我的 bashrc 文件中添加了路徑:
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
我希望這會有所幫助.
