問題描述
我目前已在我的計算機上下載并使用了 continuum analytics 的 Python 發行版(稱為 anaconda).我的問題是我想將 virtualenv 用于燒瓶項目，而 anaconda 會閃爍警告說不支持虛擬環境".有什么辦法可以在同一臺計算機上運行兩個發行版，股票 python 和 anaconda?
I currently have continuum analytics' python distribution (called anaconda) downloaded and in use on my computer. My problem is that I want to use virtualenv for a flask project and anaconda flashes a warning that says "virtual env is not supported". Is there any way i can run two distributions, stock python and anaconda on the same computer?
推薦答案
當然，如果你想單獨使用 Anaconda 發行版，你可以設置一個別名來運行那個版本，并且將 stock python 保留為默認值.
Sure, if you want to use the Anaconda distribution separately, you can set up an alias to run that version and leave the stock python as the default.
p>
在您的 .bash_profile 文件中，Anaconda 安裝程序可能會放入以下行:
In your .bash_profile file, the Anaconda installer probably put the following line:
export PATH="/path/to/your/anaconda/bin:$PATH"
注釋掉這個，并添加一個別名；例如
Comment this out, and add an alias; e.g.
alias pyconda='/path/to/your/anaconda/bin/python'
然后您可以通過在新終端中運行 pyconda 來運行您的 Anaconda python 發行版.
You can then run your Anaconda python distribution by running pyconda in a new terminal.
更新
實際上，當您想使用 anaconda 安裝中的所有內容而不是僅使用 python 時，將它放在您的路徑中可能會更好(這就是您的 ipython 最初損壞的原因).
It'd actually probably be better to put everything in the anaconda install into your path when you'd like to use it instead of just python (this is why your ipython broke initially).
為此，請設置一個別名，如下所示:
To do this, set up an alias such as the following:
alias anacondainit='export PATH="/path/to/your/anaconda/bin:$PATH"'
然后，您的 anaconda 安裝將成為該終端會話中所有內容的默認設置.
Then your anaconda install will be the default for everything in that terminal session.
例如，打開一個新終端后，嘗試以下操作:
For instance, after opening up a new terminal, try the following:
amorgan$ python # on a freshly opened terminal, this will load your default distro
Python 2.7.2 |EPD 7.2-1 (32-bit)| (default, Sep 7 2011, 09:16:50)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "packages", "demo" or "enthought" for more information.
>>> exit()
amorgan$ anacondainit #initialize anaconda
amorgan$ python #now when we run python, it will load the anaconda distro
Python 2.7.6 |Anaconda 1.8.0 (x86_64)| (default, Nov 11 2013, 10:49:09)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>
要再次使用您的其他發行版，只需加載一個新終端，從而將 anaconda 排除在您的路徑之外.
To use your other distribution again, just load up a new terminal, thus getting anaconda out of your path.
