Install error 'The version specified ('egg_info') is an invalid version'

[LeeDongGeon1996]

Hi, thank you for being our user and detail report. Based on my experience, it was not easy to troubleshoot when installing pythonnet.

There are two solutions for you:

1. (RECOMMENDED)If you are available to use Conda environment, I recommend you to run conda install -c conda-forge pythonnet for pythonnet and use our current official release.
2. Or, if you still want to install directly from the repo, you should build first and install the wheel by running:

   # Requirements: wheel
   # 3.6.1 is not official release version number, but needed for unofficial build. 
   python setup.py 0.6.1 bdist_wheel
   pip install dist/stock_indicators-0.6.1-py3-none-any.whl

Thanks for your answer!

1. I want to keep freqtrade as default as possible, so i tried without installing conda.
2. Got it running with the following line in my custom dockerfile RUN git clone https://github.com/DaveSkender/Stock.Indicators.Python.git && cd Stock.Indicators.Python/ && python3 setup.py 0.6.1 bdist_wheel && pip3 install dist/stock_indicators-0.6.1-py3-none-any.whl

The build is completed now and i can run the freqtrade instance. Unfortunately the stock-indicator imports are throwing an error. Do i need to install anything else?

Looks like the error is from pythonnet and it's telling you don't have Mono runtime on your system. To use pythonnet in Unix-based system, you must have Mono runtime installed.

• pythonnet/pythonnet#1551
• https://www.mono-project.com/download/stable/#download-lin-ubuntu

(They have been trying to avoid Mono dependency. AFAIK, it is already available in their dev branch, but I'm not sure it will be compatible with stock-indicators.)

Thanks for yor links, managed to get it installed from the mono-project page instructions.
Unfortunately getting a different error now.

The variable dataframe is a pandas dataframe containing the ohlcv data e.g. close price would be dataframe['close']. With dataframe['sma'] i'm adding another series with the sma values. I dont know what exactly you are expecting as quotes. Is this error related to the variable i'm passing to indicators.get_sma or is it a different one?

If this is getting to complicated now, i'd be fine if we close the issue. Was interested in some of your indicators but then i need to try to write them by myself or find a different library.

[LeeDongGeon1996]

Yeah, it's about the parameter. You are passing pandas.dataframe instance for quotes. But our library has its own Quote class, stock_indicators.indicators.common.quote.Quote. You have to pass Iterable object of our Quote instances. You can create like this:

from stock_indicators.indicators.common.quote import Quote

quotes = [ Quote(date, o, h, l, c, v) for date, o, h, l, c, v in your_feed ]        

Also, we already have well-organized documentation, please refer to:

• get_sma()
• Historical Quotes

Thank you for the good first issue. If you have further questions, always welcome :)
