Unable to load package for //py/web:requirements.txt: not found.

[skyl]

I'm trying to add a simple Django app to my bazel monorepo.

To my root WORKSPACE I've added:

### rules_python
load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")
git_repository(
    name = "io_bazel_rules_python",
    remote = "https://github.com/bazelbuild/rules_python.git",
    commit = "fa6ab781188972aa2710310b29a9bccaae7fd7fe",
)
# Only needed for PIP support:
load("@io_bazel_rules_python//python:pip.bzl", "pip_repositories")
pip_repositories()
load("@io_bazel_rules_python//python:pip.bzl", "pip_import")
pip_import(
    name = "pyweb",
    requirements = "//py/web:requirements.txt",
)
load("@pyweb//:requirements.bzl", "pip_install")
pip_install()
### end rules_python

Then, at py/web/requirements.txt I have a normal requirements file from pip freeze.

I have a BUILD file at py/web/myapp/BUILD with:

package(default_visibility = ["//visibility:public"])

load("@pyweb//:requirements.bzl", "all_requirements")

py_binary(
    name = "manage",
    srcs = ["manage.py"],
    python_version = "PY3",
    deps = all_requirements,
)

I try to run bazel run //py/web/myapp:manage but my requirements.txt can not be found:

ERROR: error loading package '': Encountered error while reading extension file 'requirements.bzl': no such package '@pyweb//': Trac

                repository_ctx.path(repository_ctx.attr.requirements)
Unable to load package for //py/web:requirements.txt: not found.

I'm sure I'm missing some small detail here. I wonder if someone can help me spot it. Thanks!

You need an empty BUILD file in py/web

Thank you @ali5h.

After fixing this I still can not get rules_python to work however, I get an error similar to this one: #102
