今日下午打開idea軟件,提示如下信息:

截圖:

可以很顯眼的看到caused by java.net.BindException: Address already in use: bind,可以猜想是端口地址被佔用了,於是到網站查找相關解答,找到了比較符合的(一模一樣)的情況的解答

2. 問題分析

在itellij idea官方論壇中找到類似問題的討論

截圖:

在這個回答中總結的一些可能的方法。至少此時是可以通過重啓電腦使得idea再次工作(可能開啓太多軟件應用,佔用了很多端口)。

## 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. 問題解決

個人情況: 退出當前開啓的程序,重啓電腦,解決。
