conda创建环境及激活环境失败问题

创建环境

#创建环境
conda create -n environment_name
#激活环境
conda activate environment_name
#查看虚拟环境列表 (查看所有环境名)
conda-env list
#查看环境(配置) 
conda list

激活环境时失败

遇到问题如下：

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 “. /home/wjl/anaconda3/etc/profile.d/conda.sh” >> ~/.bashrc or, for allusers, enable conda with
$ sudo ln -s /home/wjl/anaconda3/etc/profile.d/conda.sh
The options above will permanently enable the ‘conda’ command, but they do NOT put conda’s base (root) environmenton 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="/home/wjl/anaconda3/bin:$PATH"
^^^ The above line should NO LONGER be in your ~/.bashrc file! ^^^

解决方法
执行下面代码：

# 激活环境
source activate
# 退出环境
source deactivate

然后重新激活环境：

conda activate environment_name
