Hi there. We have a

shell_command

as a dependency of our

pex_binary

to generate css using tailwind. We're able to get the file into our built pex but we can't seem to get it to the correct path. Is there something we're overlooking with the use of

root_output_directory

here? With the default

for

root_output_directory

the css file ends up in our pex at

/src/python/apps/internal_tools/theme/css/dist/styles.css

With

src/python/apps

set as

root_output_directory

we get an error:

Copy code

NoSourceRootError: No source root found for `internal_tools/theme/static/css/dist`.

Our

root_patterns

contains

"src/python/apps"

. This is the `shell_command`:

Copy code

shell_command(
    name="npm_build",
    command="npm run build",
    tools=["npm", "node", "sh"],
    execution_dependencies=[":npm_install", ":tailwind", *template_dirs],
    output_files=["../static/css/dist/styles.css"],
    runnable_dependencies=[":npm", ":node"],
    root_output_directory="/",
)

We tried this as an

adhoc_tool

as well but got the same

NoSourceRootError

. Ultimately we want the file at

/internal_tools/theme/css/dist/styles.css

Hmmm, I'm not exactly sure. I'm a bit surprised it ends up at

src/python/apps/internal_tools/...

. Can you share your

pex_binary

target(s)?

Copy code

pex_binary(
    name="uvicorn",
    entry_point="uvicorn",
    args=["internal_tools.project.asgi:application", "--port", "3000"],
    dependencies=["./theme/static_src:npm_build_result", ":site"],
)

shell_command(
    name="npm_build",
    command="npm run build",
    tools=["npm", "node", "sh"],
    execution_dependencies=[":npm_install", ":tailwind", *template_dirs],
    output_files=["../static/css/dist/styles.css"],
    runnable_dependencies=[":npm", ":node"],
    root_output_directory="/",
)

experimental_wrap_as_resources(name="npm_build_result", inputs=[":npm_build"])

Thanks. I think it'd be helpful to know what the exact pex invocation pants is constructing. You can extract it by running with

pants --keep-sandboxes=always ...

, finding the relevant path in the output, and then looking at the

__run.sh

in that
