Vim74：E149对不起，help.txt没有帮助

Question

I just downloaded and installed vim74 on to my linux box. I'm only installing locally, for the user. When I go into vim, and do :help, I get the error.

I tried adding:

let $VIM='home/myuser/vim74'
let $VIMRUNTIME='home/myuser/vim74/runtime'

to my .vimrc but it didn't help. How can I fix this?

When building vim yourself and installing locally it seems that you need to generate the helptags manually from within vim since the build process doesn't seem to do it. I ran into this very same issue when building the latest vim version 8.0.311. I followed the link in Ben Klein's comment above, but both my &helpfile and &runtimepath were correct, yet I still received the E149 error when doing :help which I assume is your situation as well postelrich.

I found the helptags solution here:

https://github.com/Homebrew/homebrew-core/issues/1087

Even though I was installing vim locally on a centos system and not a mac, the issue seems to be universal. I just replaced $VIMRUNTIME with the path to the local vim runtime installed from make install, which in your case may be something like /home/myuser/vim74/runtime

Specifically I ran this from within vim:

:helptags ~/share/vim/vim80/doc

In your case you will probably run something like:

:helptags ~/vim74/runtime/doc

Once done, :help should immediately start working again without having to restart vim.
