使用tox与Anaconda python

在Ubuntu系统上,我试图用tox和多个python版本测试一个python包。我试图测试的一个python版本是64位Anaconda Python 2.7。在我开始使用Tox进行测试之前,我首先需要让virtualenv与Anaconda合作,因为Tox在内部使用virtualenv。

如您所见,virtualenv已安装在我的Anaconda环境中:

$ conda install virtualenv
Fetching package metadata: ....
Solving package specifications: ....................
# All requested packages already installed.
# packages in environment at /home/me/software/anaconda:
#
virtualenv                13.0.1                   py27_0  

但是,尝试创建虚拟环境失败:

$ mkvirtualenv test
New python executable in test/bin/python
Installing setuptools, pip...
  Complete output from command /home/me/....envs/test/bin/python -c "import sys, pip; sys...d\"] + sys.argv[1:]))" setuptools pip:

如何让virtualenv与Anaconda合作?

我觉得回答这个问题已经很晚了,你可能已经解决了......但仍然没有答案,所以无论如何我都会给你一个! 我将提供可以在其他网站上找到的食谱,我将列出各种来源,以便如果链接中断,答案仍然可以在这里看到。

首先,mkvirtualenv是一个由virtualenvwrapper包定义的命令,而不仅仅是virtualenv。 其次,使用Anaconda python创建虚拟环境的方式(命令)与安装了virtualenv的标准python不同。

创建虚拟环境

使用Anaconda python,要创建virtualenv,应按照以下顺序创建一个:

conda create -n envname python=x.x anaconda

其中envname是您的虚拟环境的名称,并且您已通过以下方式检索了要使用的python版本:

conda search "^python$"

激活虚拟环境

要激活虚拟环境,请执行以下操作:

source activate envname

将软件包安装到虚拟环境

将软件包安装到新的虚拟环境类型

conda install -n envname [package]

停用虚拟环境

停用虚拟环境

source deactivate

删除虚拟环境

要删除虚拟环境,请执行

conda remove -n envname -all
