环境搭建 - anaconda 创建python2.7环境中打开编译器确是3.6版本

Question

1.系统python版本为3.6，如何在anaconda多个环境中，如何在python2.7这个环境打开编译器去编程，
我已激活2.7版本，但是在里面输入jupyter，spider等等都是3.6？
想要打开后为2.7的

Answer 1

Different environments can be created using the virtualenv tool. First, python2.7 and 3.6 versions must be installed in your system.

Answer 2

If you activate it via conda create -n py27 python=2.7 这类语句创建了anaconda 的 2.7环境的话，那么你只需要通过activate py27就能激活它了（windows平台）,linux和mac平台通过source deactivate py27, then the command line uses that virtual environment

If you have created different virtual environments, use it under the IDE like this:

This is a virtual environment created under Pycharm. The setting method is: file->default settings->project interpreter. Then you can choose the virtual environment you installed. Other IDEs should also be able to set it up. Pycharm is very easy to use and is recommended
