scrapercompose_scraper_1 exited with code 1

[olegario96]

I cloned the repository and tried to execute the two steps from the README.md. The problem, when I execute docker-compose up the following messages are show:

What can be?

Hi Olegario,

I tried to just run the scrapy crawl quotes command in the /bin/ash shell, and got this error:

It seems from scrapy/scrapy#3143 that this is an issue with Scrapy itself in Python 3.7 (in which async is a reserved variable name). You might want to try choosing a different image to downgrade the version of Python; feel free to submit a PR if that works!

By the way, this is a fairly 'special' implementation of anonymous scraping which uses the Tor control port to periodically change your apparent IP address. If you don't need this functionality, you could use a simpler image like docker-tor-privoxy-alpine.

How can I downgrade to version 3.6?

[olegario96]

I managed to change the Python version using this dockerfile

# Adapted from trcook/docker-scrapy
FROM python:3.6-alpine
RUN apk --update add python3
RUN echo 'alias python=python3.6' >> ~/.bashrc
RUN apk --update add libxml2-dev libxslt-dev libffi-dev gcc musl-dev libgcc openssl-dev curl
RUN pip install scrapy scrapy-fake-useragent stem pyparsing python-dateutil requests
COPY tutorial /scraper/tutorial
COPY wait-for/wait-for /scraper/tutorial
WORKDIR /scraper/tutorial
CMD ["./wait-for", "tor:9050", "--", "scrapy", "crawl", "quotes"]

But the problem continues

I removed the --silent from the curl command and it says:

Received HTTP code 500 from proxy after CONNECT

torrc file needs to be updated to work

add this line:

SOCKSport 0.0.0.0:9050
