vim cannot syntax check js files

Question

I don’t know what’s going on, normal syntax checking cannot be performed in the js file

This is the problem that occurs after installing this plug-in

ruanyl/vim-eslint

After I uninstall this plug-in, I can check the grammar normally. Does this require any additional configuration? , I don’t need it according to the documentation on git. Looking at your configuration file, brother, there is no additional configuration.

Already executed npm install

Screenshots that cannot be checked normally

Answer 1

Have you installed the dependencies of vim-eslint?
Plug 'ruanyl/vim-eslint', {'do': 'npm install'}

Answer 2

In fact, the best check is to run it in the browser and try it.
