make requires PyYAML

[weiss-d]

On Pop!_OS 20.04 make bursts with errors asking to install PyYAML. After pip3 install --user PyYAML it works fine.

Full error output:

Thanks for posting this. Because the way I define plugins inside a YAML file, and vim only knows to parse JSON, it looks for these tools (in this order) in-order to convert YAML to JSON:

• yj
• yq
• yaml2json
• ruby
• python + PyYAML installed

If none of these tools are present, it fails because it can't parse the YAML. I'm not familiar with Pop!_OS, can you think of a way to convert YAML to JSON with the tools installed on Pop!_OS?

Hi, @rafi! Pop!_OS is based on Ubuntu and none of these options are installed by default in Ubuntu 20.04 either.

Unfortunately this is the compromise I must take in-order to configure my plugins in YAML format. This is where the tools are being detected: https://github.com/rafi/vim-config/blob/master/config/init.vim#L348-L375

You'll have to pip3 install --user PyYaml or install yj/yq unfortunately.

Hi there,

Having a bit of difficulty getting yj or yq detected on install even though the binaries are present in $PATH. I've downloaded the binaries and confirmed that they are executable and present as the exact names of yj or yq in $PATH - but still I receive the error recommending install of PyYAML. I can only get make to install all of the plugins by only having PyYAML in my environment.

This problem occurs on Ubuntu 20.04 and a docker image based on Ubuntu 22.04 through my testing.

PyYAML/yj/yq/etc. is no longer needed. Pushed a whole new rewrite of vim-config, 100% lua and lazy.nvim as package-manager, check it out...
