This seems to work, can you please review comment to make sure that it is appropriately working for me the way that it is desired to work?

$ ape compile -f
INFO: Compiling 'Token.vy'.
ERROR: (VyperCompileError) Token.vy
VersionException:line 1:0 Version specification "0.3.9" is not compatible with compiler version "0.3.7"
$ cat contracts/Token.vy | grep "@version"
# @version 0.3.9
$ cat ape-config.yaml
name: TokenProject
plugins:
  - name: vyper
vyper:
  version: 0.3.7
$ pico ape-config.yaml
$ cat ape-config.yaml
name: TokenProject
plugins:
  - name: vyper
vyper:
  version: 0.3.9
$ ape compile -f
INFO: Compiling 'Token.vy'.

Note: This seems to work for me, when the pragma matches the config it works and when it doesn't it fails with the error. Is this the desired effect?

I can reproduce the same result. I just want to make sure this is what we want @antazoey

[sabotagebeats]

also:
if i do the opposite, where they are not the same it also fails in the same manner:

$ ape compile -f
INFO: Compiling 'Token.vy'.
ERROR: (VyperCompileError) Token.vy
VersionException:line 1:0 Version specification "0.3.7" is not compatible with compiler version "0.3.9"

[sabotagebeats]

as requested I have tested it without the pragma now and it still compiles:

$ cat ape-config.yaml
name: TokenProject
plugins:
  - name: vyper
vyper:
  version: 0.3.9
$ cat contracts/Token.vy | grep "@version"
$ ape compile -f
INFO: Compiling 'Token.vy'.

[sabotagebeats]

it also works if there is no pragma and no version in the config:

$ cat ape-config.yaml
name: TokenProject
plugins:
  - name: vyper
$ cat contracts/Token.vy | grep "@version"
$ ape compile -f
INFO: Compiling 'Token.vy'.

[sabotagebeats]

it also works if there is only a pragma and there is not a version in the config:

$ cat ape-config.yaml
name: TokenProject
plugins:
  - name: vyper
$ cat contracts/Token.vy | grep "@version"
# @version 0.3.7
$ ape compile -f
INFO: Compiling 'Token.vy'.

I have the same results as @sabotagebeats i just want to make sure it works as intended
