Use wget to download the installation package
wget https://repo.anaconda.com/archive/Anaconda3-2021.11-Linux-x86_64.sh
Or use bash to install, the directory location of the bash+ installation package:
bash ~/Downloads/Anaconda3-2023.03-1-Linux-x86_64.sh

After completing the above two methods, the following steps are the same:
Enter yes and press the Enter key. Press Enter to select the default installation directory (by default, a folder named anaconda3 is created in the user's home directory as the installation address)

The last step is to initialize Anaconda. In this step, you only need to enter yes according to the prompts. The interface is as follows:

If you do not want conda's base environment to be activated on startup, set the auto_activate_base parameter to false:
conda config --set auto_activate_base false

Install

Finished downloading the Linux version of pycharm.

First enter the bin file of the installation package:

cd pycharm-community-2023.1.3
cd bin

Finally, open Pycharm.

sh ./pycharm.sh

uninstall

Find the pycharm folder that you unzipped at that time. I unzipped it under /usr/;

Use the command:ls -lh to view the files and folders in the folder, as shown below:
After finding the pycharm folder, Enter the command: sudo rm -r pycharm to delete.
After reaching this step, it has not been completely uninstalled, and there is still the configuration environment of pycharm.
Because generally after installing pycharm, a hidden file directory will be created in the home directory to view the hidden file directory information, ls -a.
After finding the file directory, enter the command: rm -r ~/.PyCharm2021.3/ OK,

Use the command again: ls -a to check and find that it has been completely deleted.
