Hi, can you provide more details on what you're trying to do, what command you're running, what the inputs (e.g., requirements.txt) are?
That error indicates that you're trying to build a PEX with an entry point that is the shell command line
dagster api grpc --use-python-environment-entry-point -h 0.0.0.0 -p 4321 -f ./jobs/repository.py
, which is not possible to do. An entry point needs to point to something inside the pex.

hi
python_sources() # BUILD #pex_binary( # entry_point="dagster", # execution_mode="venv", ##script="dagster api grpc --use-python-environment-entry-point -h 0.0.0.0 -p 4321 -f ./jobs/repository.py", #)
An entry point needs to point to something inside the pex. Can you give me an example how?

script
would be something like
script="dagster"
, not all those args after. Then you would run it like
./pants run path/to:dagster -- api grpc --use-python
And you probably need to explicitly add a dependency on your
python_requirement
target for
dagster
, something like
Copy code
pex_binary(
   dependencies=["3rdparty/python#dagster"],
   ...
)
(adjust the address for where you have your requirements.txt)

thanks eric the PEX file I need is of the dagster gRPC server [10:31 AM] After changing to script i am getting this error [10:31 AM] pex.pex_builder.InvalidExecutableSpecification: Could not find script 'dagster api grpc --use-python-environment-entry-point -h 0.0.0.0 -p 4321 -f ./jobs/repository.py' in any distribution within PEX!

Yes, because you're using the
script
as the whole list of arguments. It should just be
script="dagster"

But i have already specified dependencies elsewhere throughout pants via poetry
