I can't get ranger to work
the floating coc-explorer worked one time.
none of the "leader" commands seem to work.

[ChristianChiarulli]

Well a lot of this is still pretty Alpha so bare with me.

• Your coc healthcheck is failing so thats issue number one

• If by the leader commands you mean vim-which-key I haven't set them up in this repo yet. So stay tuned for that video.

• you have this path set 'Using: g:python3_host_prog = "/home/nvim/.miniconda/envs/neovim/bin/python3.8"' That's my path so I know that can't be right go under general directory remove the paths.vim file. I'll update this soon.
  After removing paths.vim make sure to pip3 install pynvim

• Try some of these things and see if it helps if not post diagnostics again

[jtfogarty]

Hey Chris, No worries. Just want to give feed back and help document. Is python 3.8 required? I missed that detail. Is miniconda required?

I'll wait on the leader commands

Thanks! Great work!

[ChristianChiarulli]

@jtfogarty while python3.8 is not required, I recommend installing pynvim for python3 with:

pip3 install pynvim

This should improve some of the diagnostics for CoC.

Also (and this is the important part) by default Neovim looks for your default python binary, how do you know which one that is just enter:

which python

which python3 # if you're on an older version of Ubuntu, I think FocalFlossa has default python as python3

Now you could also force Neovim to look at another Python binary you have installed with:

let g:python3_host_prog = expand("<path to python with pynvim installed>")
let g:python3_host_prog = expand("~/.miniconda/envs/neovim/bin/python3.8") " <- example

I use Miniconda only because I do some datascience stuff and I find having conda installed very useful for things like cudatoolkit and cuDNN. However you do not need miniconda, you can use any python virtual envioronment manager such as: virtualenv, pyenv etc..

The reason I install pynvim in a virtual environment and point it there is because I don't like installing things on my system version of python.

Another thing would be to make sure to install a clipboard tool for copy paste something like xsel.

Thanks for the feedback, keep it coming!

I want to clear up this process for as many people as possible.

[ChristianChiarulli]

Also for coc-explorer try this:

:CocInstall coc-explorer

[ChristianChiarulli]

@jtfogarty Thank you! When I get a chance I'll add this to the wiki.

[jtfogarty]

@ChristianChiarulli
I pushed my config to https://github.com/jtfogarty/nvim

The latest install process is here
https://gist.github.com/jtfogarty/3ac5ca11b868a3b992340d18d1f1632c

I have to do one of the below, otherwise chechhealth can not find nvr;

• I have to add /home/nvim/miniconda3/bin to the $PATH
• or I have to activate the nvim python environment

I'm seeing this behavior on both OS X and Linux

Is this correct?

[ChristianChiarulli]

@jtfogarty

This file: https://github.com/jtfogarty/nvim/blob/master/general/paths.vim

needs to point to the python version you installed pynvim and nvr on. That is really all it should take. I'll try to think more on it, but that's how it should work.

Can it find pynvim without adding miniconda to $PATH or activating the environment?

[jtfogarty]

@ChristianChiarulli
without the $PATH variable set, it can find pynvim but it can't find nvr

I've also seeing that if I'm editing a file and I execute :w the airline bar goes away.

[ChristianChiarulli]

Try changing python3.8 to python at the end of the miniconda path

[jtfogarty]

I changed

let g:python3_host_prog = expand("~/.miniconda/envs/neovim/bin/python3.8")

to

let g:python3_host_prog = expand("~/.miniconda/envs/neovim/bin/python")

but the same issue. without ~/.miniconda/envs/neovim/bin in the path the error is

nvr executable is not found

[ChristianChiarulli]

I'm going to install Ubuntu in a VM and try and troubleshoot this. What version of Ubuntu are you on?

[jtfogarty]

18.04

[ChristianChiarulli]

Ok so I think I know what the issue is with nvr.

When you pip install neovim-remote nvr is installed in .local/bin

so you will need to add .local/bin to your PATH or move that binary to somewhere like /usr/bin

The reason I never saw this error is because I already had them in my path
This is also true for ueberzug for image previews

so your python host is working just fine its just that the binaries were hidden from us.

try adding the following to your bashrc or zshrc:

export PATH=/home/$USER/.local/bin:$PATH

I can't get ranger to work

The same problem with MXLinux.
How I solved:
NOTE I used to try nvim appimage and compiled one - Both are working.
For appimage 'cause it is easier:
https://github.com/neovim/neovim/wiki/Installing-Neovim

   curl -LO https://github.com/neovim/neovim/releases/download/nightly/nvim.appimage
   chmod u+x nvim.appimage
sudo mv nvim.appimage /opt/
sudo ln -sf /opt/nvim.appimage /usr/local/bin/nvim 

check if /usr/local/bin is in your PATH - usually it is by default
That's it with current version of neovim (0.5 ...)
For ranger to work in neovim:

• removed ranger - sudo apt remove ranger
• install dependencies according to https://github.com/ranger/ranger
• install ranger with pip3 (I installed python3 only - python2 is disabled in nvim)

    sudo pip3 install ranger-fm

-start and try ...

P.S. If you don't need image preview you can use lf which is faster with plugin https://github.com/ptzz/lf.vim or
this one https://github.com/voldikss/vim-floaterm#use-as-a-ranger-plugin
