Question

我想安装miniconda并可以访问conda的软件包，特别是sfepy。但是我不希望它接管我当前的python定义。我认为conda只是我可以使用的许多Python环境。

最初，我尝试在安装miniconda时停用这两个选项，如下所示。

安装完成后，我将miniconda路径添加到临时cmd，导航到包含conda.exe的目录，并尝试安装sfepy

set PATH=C:\ProgramData\Miniconda2;%PATH%
cd C:\ProgramData\Miniconda2\Scripts
conda install sfepy

这将产生错误ImportError: cannot import name requests。我知道我使用的是正确的python发行版，因为当我输入python时，我会在cmd中得到以下内容

Python 2.7.15 |Anaconda, Inc.| (default, May  1 2018, 18:37:09) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

那是Anaconda发行版。更令人惊奇的是，现在我可以通过键入

导入requests包了

>>> import requests
>>> requests
<module 'requests' from 'C:\Program Files (x86)\Plaxis\PLAXIS 2D\plxscripting\requests\__init__.pyc'>

但是，正如您所见，它是从另一个python安装中导入的。我也知道requests is included with the conda的安装如下所示：

我只是不知道为什么首先从另一个目录获取它。

我真的不想随便定义路径变量。有什么方法可以从cmd中生成一个临时环境，该环境可以在需要时为我定义所有环境变量？我不想让conda接管我的系统python ...

谢谢。
