How to remove vim error prompts?

Question

A vim installation package on github

Most of them can be used. Does anyone know how to solve this?

Answer 1

Looks like this plugin requires an external program to perform syntax checking on composer.json.
Not all Vim plug-ins can be used directly, many require external programs.

viaCursorMoved Are events triggered too often?
In addition, syntax checking plug-in is recommended to use syntastic
Of course, you still have to install various external grammar checkers yourself

JSON example:

syntastic calls an external program jsonlint 对 *.json Perform a syntax check and you can see that there is an extra brace in the last line
Of course you have to install it yourselfnpm install -g jsonlint

Answer 2

Won’t the error message be automatically removed after pressing Enter? If you want to completely eliminate the error and make it no longer play, then you have to find the plug-in that reported the error and modify it correctly or delete it.

Answer 3

The prompt message looks like a JSLint plug-in, indicating that the js parser is not installed. Try installing a jsc, js (spidermonkey) or nodejs
