Error on startup

[mayanksuman]

My setup is similar to this gist. However, I am getting following error on startup.

Error in packer_compiled: ...pack/packer/start/cmp-tabnine/lua/cmp_tabnine/source.lua:53: attempt to index local 'latest' (a nil value)
Please check your config for correctness

It looks like you do not have the TabNine binary installed. I've added a proper error message in c3a168e. Please verify your installation by running install.sh

[mayanksuman]

I forgot to mention in the issue description. Actually, I have TabNine binary (which I checked in the file explorer). However, still this issue comes.

Screenshot of vim startup (after updating and running install.sh). I have TabNine 3.6.8 binaries.

Are you using WSL, or is this native windows?

[mayanksuman]

No, I am not using WSL. My setup is

OS: Debian GNU/Linux bookworm/sid x86_64 Kernel: 5.10.0-8-amd64 DE: GNOME 3.38.6 Shell: zsh 5.8 NVIM v0.5.0 LuaJIT 2.1.0-beta3

[tzachar]

Ok, can you do a find . in the binaries dir?

[mayanksuman]

The result for find .

.
./3.6.8
./3.6.8/x86_64-unknown-linux-musl
./3.6.8/x86_64-unknown-linux-musl/TabNine
./3.6.8/x86_64-unknown-linux-musl/TabNine-deep-cloud
./3.6.8/x86_64-unknown-linux-musl/TabNine-deep-local
./3.6.8/x86_64-unknown-linux-musl/WD-TabNine

The result for tree in the same directory.

Can you try this patch, and show me the output?

[mayanksuman]

The version_folder in my case is empty. Got following dump

{}
{}
cmp-tabnine: Cannot find installed TabNine. Please run install.sh
{}
{}
cmp-tabnine: Cannot find installed TabNine. Please run install.sh

I then printed out binaries_folder and I got "~/.dotfile/nvim/.config/binaries", which is wrong.

I guess issue is coming due to my choice of package manager. I use packer for managing my package. packer make packer_compiled.lua that load, run and configure all plugins. Hence, the code fn.expand('<sfile>:p') is giving the output as ~/.dotfile/nvim/.config/nvim/plugin/packer_compiled.lua

[tzachar]

I am also using packer, and do not have this issue. Can you try doing require('cmp_tabnine.config').setup() before loading any cmp code? A different option would be to allow users to override the automatic detection of the binaries directory.

[tzachar]

can you also try this?

I was able to solve the issue with following diff (also submitted as PR #4 ).

Are you using WSL, or is this native windows?

I'm using wsl and got this error, how I can fix that?

[tzachar]

idk, please provide more info in a new issue.
