windows下conda安装及配置，解决遇到的问题
一、windows下conda安装
1.下载Miniconda
2.安装后配置环境变量
找到自己的安装路径，将下面三个路径添加到环境变量
D:\Users\grfood126\miniconda3
D:\Users\grfood126\miniconda3\Scripts
D:\Users\grfood126\miniconda3\Library\bin
二、conda配置
1.创建环境
D:\Users\grfood126\miniconda3\Library\bin
>conda create env
报错。提示：缺少值，需要一个名字或者前缀
CondaValueError: either -n NAME or -p PREFIX option required,
try "conda create -h" for more details
2.新建一个带前缀的环境 new_env
conda create -n new_env
3.激活环境
conda activate new_env
错误
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
To initialize your shell, run
$ conda init <SHELL_NAME>
Currently supported shells are:
- bash
- fish
- tcsh
- xonsh
- zsh
- powershell
See 'conda init --help' for more information and options.
IMPORTANT: You may need to close and restart your shell after running 'conda init'.
4.根据提示运行conda init
刚开始报错，因为上面的环境变量没有配置完全，只配置了一个D:\Users\grfood126\miniconda3
查找了很多网上的错误修改方式，有的说是没有管理员身份运行，有的说是因为之前的虚拟环境没有退出source deactivate。都不行

在用powershell打开Anaconda Prompt (Miniconda3)时发现报错
conda : 无法将“conda”项识别为 cmdlet、函数、脚本文件或可运行程序的名称。请检查名称的拼写，如果包括路径，请确保路径正确，然后再试一 次。
网上搜索问题后，发现配置conda时不止需要添加一个环境变量，修改环境变量后，conda init正常通过
5.重新激活环境
conda activate new_env
6.添加conda镜像
输入4行清华大学的通道代码
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda
conda config --set show_channel_urls yes
7.删除镜像
conda config --remove channels https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
