Datapusher Install Issues #180

Open dyaw-Drexel opened 5 years ago

I'm trying to install Datapusher on a development instance of CKAN.

When I go to install requirements using pip install -r requirements-dev.txt, this happens:

Stored in directory: /home/uhc-ckan/.cache/pip/wheels/f2/9a/90/de94f8556265ddc9d9c8b271b0f63e57b26fb1d67a45564511 Successfully built ckanserviceprovider messytables python-slugify httpretty nose SQLAlchemy flask-login json-table-schema pycparser ERROR: ckanserviceprovider 0.0.9 has requirement requests>=2.20.0, but you'll have requests 2.13.0 which is incompatible.

This reinstalls a bunch of stuff, and causes problems with CKAN, and I get odd errors when attempting to start CKAN, like ValueError: VDM only works with SQLAlchemy versions 0.4 through 0.9, not: 1.3.6

So I reverted back to a earlier checkpoint on my VM, and try to proceed without installing the requirements, and get this message when trying to start the datapusher:

python: can't open file 'example/main.py': [Errno 2] No such file or directory Does anyone know what could be going wrong there?

CKAN and DataPusher use different vitual Envs. So they should not interfere with each other.

Maybe related to this. In a fresh install inside a new virtualenv with python 3.8 I got this error after pip install -r requirements.txt

ERROR: requests 2.24.0 has requirement chardet<4,>=3.0.2, but you'll have chardet 4.0.0 which is incompatible.

Although it gets solved by upgrading pip before installing the requirements file
