(2) Description of the problem

本想着文件被删除了,也就是应用被卸载,但情况不是.

Download the file from Pycharm official website, unzip the installation, the installation step is to run under the ./bin folder pycharm.sh , so the problem comes, when the execution of this script, will run the Pycharm program directly, unable to implement reinstall program.

-–> guess whether there are some files or configuration is not deleted completely, so has been looking for the complete removal of the software under Ubuntu command

sudo apt-get autoremovesudo apt-get --purge remove pycharm

But none of them worked.

(3) Problem solving process

Find some clues in the StackOverflow to find the problem.

Located at:pycharm所在位置

/home/<user_name>/

It can hidden so press:我这里存在这种情况,文件都是隐藏的,需要用下面的命令显示

Ctrl+h

and delete the file:找到pycharm目录,删除

.pycharm<version number>

Then relaunch the application and it'll behave as the first time

(4) Results
