在 rules_nodejs bazel 中运行 yarn_install （或 npm_install ）后如何访问 node_modules 文件夹？

Question

I'm relatively new to Bazel but this has taken longer than I felt it should. I am doing yarn_install in my workspace, and I am just trying to reference the installed node_modules so that I can put them in my new docker container.

Workspace

yarn_install(
    name = "npm",
    package_json = "//:package.json",
    yarn_lock = "//:yarn.lock",
)

BUILD.bazel

load("@io_bazel_rules_docker//nodejs:image.bzl", "nodejs_image")

nodejs_image(
    name = "webapi_image",
    # gets all the files in my directory
    data = glob(
        [
            "**/*",
        ],
        # references the node modules, but doesn't work :(
    ) + ["@npm//node_modules"],
    entry_point = "//:app.js",
)

I've been able to get specific packages (ie @npm//express ) but if I try to access node_modules then I just get

no such package '@npm//node_modules': Package is considered deleted due to --deleted_packages and referenced by '//:webapi_image'

I'm not sure I totally understand why I can access individual packages (ie @npm//express ) but not node_modules (ie @npm//node_modules ).

but after bumping around, I found if I just use the structure @npm//:node_modules , then it works finally.
