Installation fails

[cp2423]

Hi, I note this extension is now under more active development within the last few days and am wondering if this is just an issue because some changes have not been merged in yet, but today I am getting the following error trying to install on a Raspberry Pi 4:

We haven't published a new version to PyPI yet. There's a few small improvements I have that are pending. I'm hoping to get that finalised in the next few days, at which point we'll publish v2.0

Hey just checking in on this. What steps can I take to install this manually until it's updated to 2.0?

I think i am getting same error when installing it in docker using following command:

# install mopidy-local and latest version of mopidy-cd extension
RUN python3 -m pip install mopidy-local Mopidy-API-Explorer git+https://github.com/antosart/mopidy-cd.git

This the docker output when building it:

I no longer get above error when installing it directly from github using following docker command (it also installs extensions mopidy-local and mopidy-cd.

RUN python3 -m pip install mopidy-local git+https://github.com/mopidy/mopidy-api-explorer.git  git+https://github.com/antosart/mopidy-cd.git

... but then following error is logged when the docker service becomes started (note that I don't have this error when I am not installing that extension)

I managed to fix the error regarding the 'cffi' package version mismatch by following docker command which installs the correct cffi version:

RUN python3 -m pip install  mopidy-local  git+https://github.com/antosart/mopidy-cd.git \
                            cffi==1.12.2 git+https://github.com/mopidy/mopidy-api-explorer.git

Thanks for the update. I experienced the same installation error and so installed with your suggested fix, after I installed git of course.

We haven't published a new version to PyPI yet. There's a few small improvements I have that are pending. I'm hoping to get that finalised in the next few days, at which point we'll publish v2.0

@djmattyg007 I am not sure to understand the quoted text but it looks like you have an unpublished fix waiting for "small
improvements" to be implemented. Could you publish that fix (not necessarily going through a new release) so that this extension can be installed seamlessly?

AFAICT installing through the following works, thus just updating the README file could be enough:

python3 -m pip install git+https://github.com/mopidy/mopidy-api-explorer.git
