deactivate python36 # for Windows

source deactivate python36 # for Linux & Mac

4、 删除一个已有的环境

conda remove --name python36 --all

5、conda包管理

5.1安装xxxx

conda install xxxx

5.2查看当前环境下已安装的包

conda list

5.3查看某个指定环境的已安装包

conda list -n python36

5.4查找package信息

conda search numpy

5.5安装package

conda install -n python34 numpy # 如果不用-n指定环境名称，则被安装在当前活跃环境 也可以通过-c指定通过某个channel安装

6、Conda 更新

6.1 更新package

conda update -n python34 numpy

6.2 删除package

conda remove -n python34 numpy

6.3 更新conda，保持conda最新
