Can't load toml cache.

Problems summary

Can't load toml cache. In my case, even if I cut it down to this level, it still echoes failed on starting.

Expected

I have no idea.

I have tested your minimal vimrc and it works for me.

It seems dein#load_cache_raw() error. Please debug it like this.

call dein#load_cache_raw(g:dein#_vimrcs)

Why you have called dein#load_cache_raw() manually? I think it is not called in startup.

So please read below code.

  let lines = [
        \ 'if g:dein#_cache_version !=# ' . g:dein#_cache_version . ' || ' .
        \ 'g:dein#_init_runtimepath !=# ' . string(g:dein#_init_runtimepath) .
        \      ' | throw ''Cache loading error'' | endif',
        \ 'let [plugins, ftplugin] = dein#load_cache_raw('.
        \      string(g:dein#_vimrcs) .')',
        \ "if empty(plugins) | throw 'Cache loading error' | endif",
        \ 'let g:dein#_plugins = plugins',
        \ 'let g:dein#_ftplugin = ftplugin',
        \ 'let g:dein#_base_path = ' . string(g:dein#_base_path),
        \ 'let g:dein#_runtime_path = ' . string(g:dein#_runtime_path),
        \ 'let g:dein#_cache_path = ' . string(g:dein#_cache_path),
        \ 'let &runtimepath = ' . string(&runtimepath),
        \ ]

Please compare both g:dein#_cache_version and g:dein#_init_runtimepath with your state file values. If it is not same, it will be returned before dein#load_cache_raw() call.

I think g:dein#_init_runtimepath is not same. Why it is not same? I don't know... It should same if you use the minimal vimrc.

call dein#load_cache_raw(g:dein#_vimrcs)

echo dein#load_cache_raw(g:dein#_vimrcs) is better. Please check the return value is not empty lists.

[Shougo]

Have you change &runtimepath after dein#load_state()?

[uga-rosa]

g:dein#_cache_version and g:dein#_init_runtimepath are same with state file values. echo dein#load_cache_raw(g:dein#_vimrcs) returned the value is NOT empty list. The only change I made to the runtimepath that I set up myself is the addition of dein before dein#load_state().

P.S. dein#load_cache_raw() is not called in startup.

[Shougo]

OK. So please debug your state file. It checks g:dein#_cache_version and g:dein#_init_runtimepath.

P.S. dein#load_cache_raw() is not called in startup.

The reason is found. It fails the version check or the runtimepath check. The script is under your cache directory. You can debug it.

[Shougo]

g:dein#_cache_version and g:dein#_init_runtimepath are same with state file values.

It is really same when the script is executed? If so why the check is failed? dein#load_cache_raw() is not called.

[Shougo]

I can remove the check easily. But it is not the true fix for it.

[uga-rosa]

I don't know the cause, it's not reproducible, and there are other options for the plugin manager. I can't motivate myself any more. I'm sorry.

[Shougo]

Oh
