2 解决办法

当上网查看相关的词条时，可以看到有一条[https://github.com/vim/vim/issues/3280](https://github.com/vim/vim/issues/3280)描述了出现Error detected while processing function <SNR>39_Highlight_Matching_Pair: in bash file #3280时的解决办法，

2.1 首先确认matchparen.vim是否最新

下面的这段解释就是让我们去检查matchparen.vim文件的时间戳，确认一下是否是最新的版本，

Please make sure that the updated matchparen.vim script is loaded.
If you execute vim without installing, old version of the script might be loaded.

To check which file is loaded, you can use the :scriptnames command.

Error detected while processing function <SNR>39_Highlight_Matching_Pair:

The message says <SNR>39, so you should check the 39th scripts in the result of :scriptnames.
If the Last Change date of the script is not 2018 Jul 3, your script is old.

vim的matchparen.vim的最新版本（或者整个runtime的最新版本）可以去https://github.com/vim/vim/tree/01164a6546b4c635daf96a1f17d1cb2d07f32a66上去查看确认。

2.2 将vim更新到最新的版本

在ubuntu上更新vim版本的方法如下所示：

sudo add-apt-repository ppa:jonathonf/vim
 
sudo apt update

sudo apt upgrade
 
sudo apt install vim

通过上面的方法我解决了Error detected while processing function <SNR>20_Highlight_Matching_Pair:的问题，当我再打开存在非对称“{}”以及在注释中含有“（）”的文件时不再报该问题。
