为何vi将.lrp后缀文件识别为tar文件且无法编辑？

Hey there! I’ve dealt with this exact frustrating issue across multiple Linux distros and macOS too—here’s what’s going on and how to fix it permanently.

What’s Causing the Error? #

Vim’s built-in tar.vim plugin (which handles browsing tar archive files) automatically associates the .lrp file extension with tar-based archives. LRP files (used for Linux Router Project systems) do have tar-like components, but they aren’t standard tar archives—so when Vim tries to load them in tar browse mode, it throws that red ***error*** (tar#Browse) message.

Since this is part of Vim’s default plugin behavior, it’s why you’re seeing it across OS X High Sierra, Ubuntu 16.04, Debian, and your colleagues’ devices, regardless of .vimrc tweaks (unless your config overrides this association).

Quick Temporary Fixes #

If you just need to edit a .lrp file right now:

• Open the file with the ++noplugin flag to skip the tar plugin for this session only:

  vi ++noplugin yourfile.lrp
  

• Or once Vim is open and showing the error, run this command to reset the filetype and disable the tar mode:

  :set filetype=text
  

Permanent Solution (No More Errors!) #

To make Vim stop treating .lrp files as tar archives forever, add one of these lines to your ~/.vimrc (or ~/.vim/vimrc on some systems):

Option 1: Force .lrp files to use plain text mode

This is the simplest approach:

autocmd BufNewFile,BufRead *.lrp set filetype=text

Option 2: Tell the tar plugin to ignore .lrp files

If you want to keep other tar-related associations intact but exclude .lrp, use this:

autocmd BufRead,BufNewFile *.lrp let b:tar_ignore=1

After saving your .vimrc, restart Vim—you’ll be able to edit .lrp files normally without any red error bars.
