Solving Vim startup errors: plug-in conflicts and repairs

Solving Vim startup errors: plug-in conflicts and repairs

introduction

When launching Vim recently, I encountered a complex series of error messages that prevented the normal use of Vim. After some troubleshooting and trying, I found that the problem lies with Vim's plug-in. In this article, I will share my diagnostic process and solution in the hope that it will help Vim users who encounter similar problems.

wrong description

The following error message appears when starting Vim:

Error detected while processing function <SNR>2_clean[1]..<SNR>2_prepare[18]..<SNR>2_new_window[1]..WinEnter Autocommands for "*"..function <SNR>54_on_window_changed[23]..airline#update_statusline[7]..airline#update_statusline_inactive:
line   12:
E10: \ should be followed by /, ? or &

This error message involves multiple functions and plug-ins, especially the airline plug-in. The E10 error in the prompt is a key clue.

Troubleshooting process

1. Plug-in conflict: Preliminary judgment may be a conflict between Vim plug-ins or a problem caused by an incorrect configuration of a plug-in.
2. Disable plugins: I tried disabling some plugins by editing the .vimrc file, but the problem persists.
3. Manually clean plugins: Ultimately, I decided to manually delete all plugin folders under ~/.vim/plugged.

solution

After removing all plug-ins, Vim can start normally. This confirms that the problem is indeed with the plugin. Here are my steps:

1. Backup: Back up the .vimrc files and ~/.vim directories before making any changes.
2. Clean plugin: Delete all contents in the ~/.vim/plugged directory.
3. Test plugins one by one : Reinstall each plugin and test Vim after each installation to determine which plugin is causing the problem.
4. Update .vimrc: Update the .vimrc file based on test results to exclude or replace problematic plugins.

in conclusion

This experience reminded me that it is very important to maintain and check Vim configuration and plugins regularly. Although plug-ins are powerful, they may also cause compatibility issues. Timely cleaning and updating of plug-ins can ensure that Vim runs stably and efficiently.
