Vim startup errors (invalid expression) Debian

问题

I'm having issues setting up Vim. Firstly I'm having a bunch of errors when start up Vim, I get these errors:

Press ENTER or type command to continue

Also, when I try to run :helptags ~/.vim/doc it doesn't load at all. It just shows a blank editor screen.

I would appreciate your help, I've searched the web for solutions but I've been unable to fix it. I really want to start using Vim. Thank you!

EDIT: I added my .vimrc

set nocompatible
call pathogen#infect()
execute pathogen#infect()
call pathogen#helptags()
generate helptags for everything in 'runtimepath'
syntax on
filetype plugin indent on

Oh my gosh! I see several issues:

E492: Not an editor command: generate helptags for everything in 'runtimepath'

You must have a line starting with generate helptags ... somewhere (your ~/.vimrc?); it should be a comment: Prepend a " to the line.

***** L9 library must be installed! *****

The FuzzyFinder plugin requires another plugin; you can get it at L9 - Vim-script library.

Error detected while processing /home/lee/.vim/plugin/refactor.vim:
line   45:
E492: Not an editor command: ^M

That's caused by Vimscript files that have Windows-style CR-LF line endings when used on Linux. Open the corresponding file(s) in Vim and convert them to Unix-style endings via

:w ++ff=unix

I hope you'll start to see the light after these. A link to your full Vim config would be helpful to further diagnose this. If you're new to Vim, it's recommended to start with a lean .vimrc, and only gradually add plugins, as you become more proficient and identify the needs.

For the E492: Not an editor command: ^M part, I actually got the same problem but the above answers didn't help. So I found this and it works for me:

For Cygwin (which I use): install dos2unix from the package installer

For Ubuntu/Debian:

sudo apt-get install tofrodos; sudo ln -s /usr/bin/fromdos /usr/bin/dos2unix

For CentOS, Fedora, ...:

sudo yum install dos2unix

Then use it this way:

dos2unix ~/.vimrc

That should clean all CRLF from the file

I see these types of errors:

Error detected while processing ~/.vim/plugin/<some_plugin_giving_you_error>:
line   45:
E492: Not an editor command: ^M

when a .gitconfig has Windows relevant [core] settings but used on a Linux box. Then when a plugin is downloaded by either a Vim plugin manager or manually, these errors start showing up.

So I would suggest checking your Git settings, delete the downloaded files, and try again.

回答4:

the simple way without any tools involve:

more .vimrc #prepare for the copy paste
vi .vimrc #start with a blank .vimrc
copy paste the original .vimrc content to the blank .vimrc
done

回答5:

Error detected while processing /home/lee/.vimrc:
line    5:
E492: Not an editor command: generate helptags for everything in 'runtimepath'

That line is not commented

Error detected while processing /home/lee/.vim/plugin/fuf.vim:
line   13:
***** L9 library must be installed! *****

FuzzyFinder needs the L9 library but it didn't find it.

Error detected while processing /home/lee/.vim/plugin/refactor.vim:
line   45:
E492: Not an editor command: ^M

On Linux, Vim doesn't like Windows line endings and you seem to have a lot of them.

line   55:
E15: Invalid expression: ["auto", "const", "double", "float", "int", "short", "struct", "unsigned", "break", "continue", "else", "for", "long", "signed", "switch", "void", "case", "default", "enum", "goto", "register", "sizeof", "typedef", "volatile", "char", "do", "extern", "if", "return", "static", "union", "while", "asm", "dynamic_cast", "namespace", "reinterpret_cast", "try", "bool", "explicit", "new", "static_cast", "typeid", "catch", "false", "operator", "template", "typename", "class", "friend", "private", "this", "using", "const_cast", "inline", "public", "throw", "virtual", "delete", "mutable", "protected", "true", "wchar_t", "size_t"]^M

Same as above, the trailing ^M is the problem.

line   58:
E15: Invalid expression: '\<\h\w*\>'^M

And so on…

This command

:%s/<C-v><CR>//

should reduce the number of errors. <C-v><CR> means "hit Ctrl+V, then hit the Enter key".

Please show us your ~/.vimrc so that we can help you further.
