thread vscode error juste is normal

[Hlaaftana]

Most editor plugins use `nim check`, and `nim check` can sometimes give errors 
a normal compilation wouldn't give. It might also be the case that to compile 
your program you use something like `-d:ssl`, but the `nim check` command might 
not use it, so some modules might break when using `nim check` (you solve this 
with config files).
