ubuntu18.04下 提示“conda:未找到命令”

在ubuntu18.04中安装了Anaconda后运行conda create提示 “conda:未找到命令”，查看vim ./~bashrc后没有添加环境变量，执行以下命令添加环境变量后运行正常

echo 'export PATH="/home/cv/anaconda3/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

/home/cv/anaconda3/是anaconda安装后的路径

cv@cv-System-Product-Name:~$ echo 'export PATH="/home/cv/anaconda3/bin:$PATH"' >> ~/.bashrc
cv@cv-System-Product-Name:~$ source ~/.bashrc 
(base) cv@cv-System-Product-Name:~$ conda -V
conda 4.10.1
(base) cv@cv-System-Product-Name:~$
