一、運(yùn)行命令報(bào)錯(cuò)
創(chuàng)建環(huán)境

conda create --name article_spider python=3.6

更新conda

conda update conda

運(yùn)行上述兩個(gè)命令時(shí)都報(bào)錯(cuò)

Fetching package metadata .......

解決方法

清華大學(xué)開源軟件鏡像站 - anaconda鏡像

#首先先添加清華的鏡像源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --set show_channel_urls yes

#如果無(wú)法解決，則刪除channels配置文件中部分內(nèi)容

#具體操作如下:
#1、快速創(chuàng)建channels配置文件的備份(保險(xiǎn)起見)
cp ~/.condarc{,.bak}

#查看配置文件的內(nèi)容
cat ~/.condarc.bak 
channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  - defaults
show_channel_urls: true

#2、刪除部分內(nèi)容
#修改后配置文件的內(nèi)容如下，只保留清華的鏡像源：
vim ~/.condarc
channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
show_channel_urls: true

二、conda 文檔
https://conda.io/docs/index.html

三、conda 簡(jiǎn)單實(shí)用

# To see a list of all your environments
conda info --envs

#To use, or “activate” the new environment, type the following
#Windows: 
activate snowflakes
#Linux and macOS:
source activate snowflakes

#Change your current environment back to the default (base):
#Windows: 
deactivate
#Linux, macOS: 
source deactivate
