在ubuntu上安装了Anaconda以后，每次启动终端都会手动步入conda的base环境linux默认启动命令行，可以通过如下指令退出conda环境：
conda deactivate并且考虑到每次都须要执行这一步能够退出，比较麻烦linux定时器，因而想要启动终端后不步入conda环境。网上推荐通过更改conda的config文件来实现：
conda config --set auto_activate_base false然而鸟哥的linux私房菜，我这儿并没有用，启动以后还是会手动步入conda的base环境。最后的解决方案是，直接更改conda的配置文件来实现：
sudo vi ~/.condarc在最后一行补充：
auto_activate_base: false至此linux默认启动命令行，完成。
通过“conda-h”查询具体的设置：
