Is it possible to force pants to use a wheel when installing a package? Despite there being wheels available for 
grpcio-tools
(and them properly showing up in our lock file), it seems 
export
causes us to build that from source which takes a really long time.
We know it's this package because tools like 
htop
show it taking all the cpu to build from source.
Outside of pants, I can see it using a wheel

Just confirming; are the wheels available compatible with the Python version within pants (and OS)?

For me yes.

Here's it showing that grpcio-tools has a wheel compatible
And same for grpcio for sanity

I can add 
--only-binary
to the requirements file, but I suspect pants might not honor that when it comes time to 
export
Checking now, though
Even though I added 
--only-binary:grpcio-tools:
to requirements.txt, my lock file still says a source package is a valid option 😢

Thanks a bunch! I used that and could see the source distribution option removed from the lock file.
