Creating a virtual Environment in Anaconda (command-line mode)

How to create a virtual environment in anaconda:

Here is the environment for creating the python=3.6 version, named py36

Conda create-n py36 python=3.6

Delete an environment

Conda remove-n py36--all

Activating the Environment

SOURCE Activate py36

Exit the Environment

SOURCE Deactivate

• In the process of creating a virtual environment, I encountered a problem that was:如果创建了多个python版本的环境，那么我应该如何去管理当中所安装的不同的包呢？并且与本机原本安装的python环境不起到冲突？

• I fix anaconda and native methods like this:

  • workaround one:

  In fact, Python provides us with two versions of the solution at the time of installation

  There is a py.exe in the Windows directory of drive C

  We can tell the Python version by starting with the Py.exe tool

  Start python2.7 pip

  Enter directly in the CMD window: py-2-m pip install XXXX

  Start python3.6 pip

  Type directly in the cmd window: py-3-M Pip install XXXX

  • workaround two:

  Find your native installed Python path (you can find it directly in path), then locate your Python.exe file and rename it.

  Such as: I renamed my native Python to Python3 and then did not rename the python that was installed in Anaconda.

  After a PIP installation is required for Python in Anaconda, enter:

  python-m pip install XXX

  And then, when installing the native Python, enter:

  Python3-m pip install XXX

• I resolved the problem of Python conflicts with Anaconda itself after anaconda into the virtual environment:

  Depending on how you started the virtual environment above, we were able to start the virtual environment that was created

  After entering the virtual environment, enter:

  Python-v

  will be able to see the version number of Python in the current virtual environment

  At this time, enter:

  PIP List

  What you see is the package installed by the PIP in your current environment.

  如果你发现你的list还是Anaconda自带的list的话，就输入：

  python -m pip list

当你安装好Anaconda之后，会出现一个Anaconda Mavigator，点击之后在里面也可以创建虚拟环境。
