可以很显眼的看到caused by java.net.BindException: Address already in use: bind,可以猜想是端口地址被占用了,于是到网站查找相关解答,找到了比较符合的(一模一样)的情况的解答

2. 问题分析

在itellij idea官方论坛中找到类似问题的讨论

截图:

在这个回答中总结的一些可能的方法。至少此时是可以通过重启电脑使得idea再次工作(可能开启太多软件应用,占用了很多端口)。

## Attempts to solve the problem

I have attempted to solve the problem by taking the following steps, but in vain:

• I attempted to reboot the computer and retry to launch IntelliJ IDEA. It did not work.
• According to some information on the Internet, I learned that it may have something to do with unavailable ports; however, I cannot find the information about which port is needed in the error message and therefore cannot solve the problem this way.
• I attempted to launch PyCharm Professional 2019.2 on the same computer, and it reported the exactly same error as IntelliJ IDEA.

I have not launched IntelliJ IDEA on this computer for several months, so I'm afraid that I cannot figure out which of the changes to my computer has caused the problem.

3. 问题解决

个人情况: 退出当前开启的程序,重启电脑,解决。
