How to make package.json work on the local file system?

[konomikitten]

I have the following project:

.
├── example
│   ├── example.py
│   └── __init__.py
├── main.py
└── package.json

example/example.py

class HelloWorld:
    def hello_world(self):
        print("Hello World!")

example/__init__.py

"""common include"""

main.py

from example import HelloWorld

def main():
    hw = HelloWorld()
    hw.hello_world()

if __name__ == '__main__':
    main()

package.json

{
  "urls": [
    ["example/__init__.py", "example/__init__.py"],
    ["example/example.py", "example/example.py"]
  ],
  "deps": [],
  "version": "0.2"
}

When I run mpremote install package.json I get the following error:

$ mpremote mip install package.json
Install package.json
Installing package.json (latest) from https://micropython.org/pi/v2 to /lib
Package may be partially installed
mpremote: Package not found: https://micropython.org/pi/v2/package/6/package.json/latest.json

The documentation: Installing packages with mpremote says this should be possible. What am I doing wrong?

Currently that is not possible without starting a minimal (Python) http server so that mip can access the package on a https url.

python -m http.server --directory <DIRECTORY>

There is a PR open to allow this without that workaround.
