1. 问题形容

今日下午关上idea软件,提醒如下信息:

能够很显眼的看到caused by java.net.BindException: Address already in use: bind,能够猜测是端口地址被占用了,于是到网站查找相干解答,找到了比拟合乎的(截然不同)的状况的解答

2. 问题剖析

在itellij idea官方论坛中找到相似问题的探讨

在这个答复中总结的一些可能的办法。至多此时是能够通过重启电脑使得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

集体状况: 退出以后开启的程序,重启电脑,解决。
