Can not get vsnip to work

[Q-Xue]

I installed vim-vsnip, nvim-cmp, vim-vsnip-integ. Below is my cmp configuration.

Tabnine and lsp both work. But vsnip does not work.

I am using Window OS.

I config vsnip: let g:vsnip_snippet_dir = 'C:\Users\eidan\AppData\Local\nvim-data\site\vsnip'

Then I create a python.json file there and copy a very simple snippet in the file.

{ "try/except": { "prefix": "try/except", "body": [ "try:", "\t${1:pass}", "except ${2:expression} as ${3:identifier}:", "\t${4:pass}" ], "description": "Code snippet for a try/except statement" } }

I open a python file, type try, I can see tabnine and lsp completion item, but no vsnip completion item.

What did I miss?

My cmp config:

set completeopt=menu,menuone,noselect

I can't understand. Did you install hrsh7th/cmp-vsnip?

That was the problem : P I forgot to install cmp-vsnip... It is working now! Thanks.
