安装的时候是用的解压Idea压缩包之后的bin/idea.sh安装的

然后想卸载，直接删除解压之后的idea程序目录是不够的，还必须把/home/目录下的.IdeaIC2017.2/这个隐藏目录给删掉才算彻底卸载，否则无法重装

To remove the product completely, do the following:

• Delete the installation directory

• Delete the "config" and "system" configuration directories. These contain IntelliJ IDEA's caches, configuration and plugins.

See http://devnet.jetbrains.net/docs/DOC-181 for the OS specific locations of these two directories.

That should be all you need.
