ubuntu 下修改~/.condarc文件

channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/linux-64
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/linux-64
show_channel_urls: true
ssl_verify: true

pkgs_dirs:
 - /home/username/anaconda3/pkgs
envs_dirs:
  - /home/username/anaconda3/envs

pkgs_dirs: 指定pkgs下载保存的目录
envs_dirs: 指定创建虚拟环境的目录

windows 下修改~/.condarc文件

如果发现D:\Anaconda\Scripts在环境变量中

# 应该使用
activate <envs>

# 而不是 
source activate <envs>

# 使用source会报错
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If your shell is Bash or a Bourne variant, enable conda for the current user with
    $ echo ". E:\Anaconda/etc/profile.d/conda.sh" >> ~/.bashrc
or, for all users, enable conda with
    $ sudo ln -s E:\Anaconda/etc/profile.d/conda.sh /etc/profile.d/conda.sh
The options above will permanently enable the 'conda' command, but they do NOT
put conda's base (root) environment on PATH.  To do so, run
    $ conda activate
in your terminal, or to put the base environment on PATH permanently, run
    $ echo "conda activate" >> ~/.bashrc
Previous to conda 4.4, the recommended way to activate conda was to modify PATH in
your ~/.bashrc file.  You should manually remove the line that looks like
    export PATH="E:\lmgod\Anaconda/bin:$PATH"
^^^ The above line should NO LONGER be in your ~/.bashrc file! ^^^
