4.Give ordinary users/super users permission to use Anaconda

Whether you install it under the root user or an ordinary user, when installing anaconda, it is best to install it in a directory that ordinary users can access, such as /usr/local, /opt, /home, otherwise ordinary users will not be able to use anaconda.
(1) Anaconda is installed under the root user, and you want to give ordinary users the permission to use anaconda.
For example, the installation location is /opt/anaconda3, execute directly under the ordinary user: /opt/anaconda3/bin/conda init bash, and then execute conda env listthe test

(2) Anaconda installed under the ordinary user , you want to give the super user (root) permission to use anaconda.
For example, the installation location is /home/xxx/anaconda3, run directly under the root user: /home/xxx/anaconda3/bin/conda init bash, and then execute conda env listthe test

If you accidentally install anaconda in a directory that is inaccessible to ordinary users, such as /root or /home/root, you can uninstall anaconda and reinstall it.
(1) Delete the installation directory: rm -rf /root/anaconda3
(2) Edit the environment variable file vi ~/.bashrcand comment or delete the path of anaconda3
(3) Make the modified environment variables take effect immediately:source ~/.bashrc
