python 工具介绍 —— Anaconda（水蟒）

官方网站

 以前，在linux下面可以使用Pyenv，那windows下面就靠这个工具了。

# 下载安装

网络不好的可以去这里直接拿安装包

安装完毕后，添加环境变量，下面是我的按照目录

D:ToolsanacondaScripts

打开一个CMD，查看conda --version

# conda --help

C:Usersloki>conda --help
usage: conda-script.py [-h] [-V] command ...

# 创建一个新环境

conda create -n py34 python=3.4

Note: 遇到一个报错

解决方法：

找到 .condarc 文件路径，我的是在C:Usersloki，修改内容为： （清华大学镜像）

channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
ssl_verify: true
show_channel_urls: true

# 按照完毕后，查看是否已经安装成功， conda env list

# 切换环境版本   activate <刚刚取的名字>

# 如果记不清了可以conda env list 命令来查询

# 卸载环境 conda remove --name py34 --all 

# 安装/卸载/更新第三方包

conda install requests    Or  pip install requests

conda remove requests    Or   pip uninstall requests

# 查看环境包信息

conda list

# 导入导出环境

conda env export -n base > d:environment.yaml  ## 导出名叫 base的环境

 conda env create -f environment.yaml  ## 导入

与JetBrains PyCharm 连接

在Setting => Project => Project Interpreter 里面修改 Project Interpreter , 点击齿轮标志再点击Add Local为你某个环境的python.exe解释器就行了
