I have the same error:

[voidstar-null]

 - ERROR curl is not installed

Try installing curl and then reinstall blink.cmp .

[HertelP]

 - ERROR curl is not installed

Try installing curl and then reinstall blink.cmp .

I Have curl installed and reinstalled blink.cmp multiple times and it still won't work.

[Re3w]

 - ERROR curl is not installed

Try installing curl and then reinstall blink.cmp .

I also have curl installed, but I specifically changed the permissions on it because my organization prohibits the use of outside downloads.

What is being downloaded through curl? Is there any way to configure a proxy?

[saghen]

The prebuilt binary for the fuzzy matching. You could:

1. Build it from source with build = 'cargo build --release'
2. Or download from the releases and place it at ~/.local/share/nvim/lazy/blink.cmp/target/release/libblink_cmp_fuzzy.so

[saghen]

@HertelP You seem to be having a different issue, are you on neovim 0.10+?

[voidstar-null]

@saghen the error is there because gsub also adds the number of replacements to the result.

https://github.com/Saghen/blink.cmp/blob/bff6c0f06bdc1114c5816b0f6b19ad6a7e15a638/lua/blink/cmp/health.lua#L28
and it is due to the above line.

It can be fixed with replacing this line with:

    or vim.uv.fs_stat(string.gsub(download.lib_path, 'libblink_cmp_fuzzy', 'blink_cmp_fuzzy'):match('(.+)%s*%d*$'))

[saghen]

Ahh thanks! Fixed that on main

[ziryth]

I had the same error with 0.7.6, which got resolved by building the fuzzy lib manually. However I just upgraded to 0,8.0 and now it fails in the same place.. this time because download.lib_path is null:

• ERROR Failed to run healthcheck for "blink.cmp" plugin. Exception:
  ...local/share/nvim/lazy/blink.cmp/lua/blink/cmp/health.lua:27: bad argument # 1 to 'fs_stat' (string expected, got nil)

[saghen]

Root issue was solved by manually installing or building since the OP couldn't use curl. The issues around health check were solved on main

[HertelP]

@saghen
My issue wasn't fixed after the update but i found the error on my side.
In case anyone is having the same issue:
I made a switch from packer to lazy and the plugin was trying to load it from the /site/pack/packer directory which caused the error. I deleted the folder .local/share/nvim/site folder and it worked as expected
