Error when using pip install mimblewimble: secp256k1-zkp-mw: finished with status 'error'

[Anynomouss]

I get this error when installing using pip on Linux subsytems for Windows:

Command "/usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-1kcu0m6s/coincurve/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-urtrob43-record/install-record.txt --single-version-externally-managed --compile --user --prefix=" failed with error code 1 in /tmp/pip-build-1kcu0m6s/coincurve/
It is rather non-descriptive unfortunately.

I also got prolblems when installing on Windows using pip:

 cl : Command line warning D9002 : ignoring unknown option '-g'

      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.

I tried alternative way of installing, installing secp256k1-zkp-mw like this worked

cd secp256k1-zkp-mw
git submodule init
git submodule update
pip3 install .

Installing mimblewimble-py like this did unfortunately not work.

git clone https://github.com/grinventions/mimblewimble-py
cd mimblewimle-py
git submodule init
git submodule update
pip3 install .

Error:

Hi!

Sorry you encountered build errors. Can you try the following way as a temp solution?

Start by installing secp256k1-zkp-mw as you did

cd secp256k1-zkp-mw
git submodule init
git submodule update
pip3 install .

then simply

pip3 install mimblewimble-py

I think it is the dependency secp256k1-zkp-mw that fails, but if already satisfied then mimblewimble-py should succeed normally.

This is just a temp solution, let me know if it worked out for you.
