在Cygwin中永久设置Anaconda的Python路径

Question

我正在尝试在我的Windows 7机器上安装Anaconda.我经常使用cygwin来完成我的命令行工作,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,并检查了必要的框以重置我的python安装的默认路径.我继续检查python的位置,最初我得到了这个......

$ which python
/usr/bin/python

从这里python工作得很好......

$ 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.

但我正试图从蟒蛇工作,所以我只需要重新定义我的道路......

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

现在我应该好好去,但是当我尝试进入python时,它只是挂起

$ python

知道为什么会这样吗？详细回报,下面......

我遇到的另一个(可能是相关的)问题是每次关闭/打开cygwin时都需要重置路径.我已将以下文本输入.bashrc和.profile以尝试永久设置路径:

# Set path to python from anaconda install
export PATH=/cygdrive/c/anaconda:$PATH

打开和关闭cygwin后,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？

Answer 1

要在Cygwin中使用交互式Python shell,我使用-i选项.

为了从Anaconda安装中获取它,我使用了上面建议的步骤:

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

然后我用-i选项在Cygwin中启动python:

$ python -i

图书馆也运作良好.例如,现在可以导入pandas库(通过Anaconda安装).

>>>> import pandas
>>>> pandas.DataFrame
<class 'pandas.core.frame.DataFrame'>

现在为了使这个永久化我在我的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

我希望这有帮助.

Answer 2

我在使用我的 Cygwin / Windows 7 系统设置 anaconda 时也遇到了问题。有效的方法如下：

1. 编辑〜/.bashrc。将以下内容添加到文件底部。

   export PATH=/cygdrive/c/Anaconda:$PATH

2. which python通过进入Cygwin 的控制台，将 Cygwin 的 python 映射到 anaconda 发行版作为证据。然而，当启动 python 时，它会挂起，迫使我 ^C 退出命令。我发现它将python -i毫无问题地启动交互式 python 解释器。

Answer 3

关于永久设置路径，请编辑主目录中的 .profile（它是一个隐藏文件）。

.profile（其他名称也有效，请参阅 bash 手册页）包含 bash 命令。当 bash 作为登录 shell 启动时执行。

在此文件的底部，输入设置路径命令：

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

至于为什么 python 挂起，请提供更多信息 - 例如 的输出是什么python -v？
