            Probably it is very old example - it uses http but modern pages use https - and amazone could rebuild page and now it has better system to detect spamers/hackers/bots and block them.

            If I use @url http://toscrape.com/ then I don't get error 503 but I still get other error FAILED because it needs some code in parse()

            I found a solution to my problem. In fact, just as I suspected, there was a missing directory to my PYTHONPATH. It was the directory that contained the gtts package.

            Solution: If you have the same problem,

            1. Find the package

            I looked at that post

            1. Add it to sys.path (which will also add it to PYTHONPATH)

            Asked 2021-May-29 at 15:29

            I'm using scrapy and I'm traying to scrape Technical descriptions from products. But i can't find any tutorial for what i'm looking for.

            I'm using this web: Air Conditioner 1

            For exemple, i need to extract the model of that product: Modelo ---> KCIN32HA3AN . It's in the 5th place. (//span[@class='gb-tech-spec-module-list-description'])[5]

            But if i go this other product: Air Conditioner 2

            The model is: Modelo ---> ALS35-WCCR And it's in the 6th position. And i only get this 60 m3 since is the 5th position.

            I don't know how to iterate to obtain each model no matter the position.

            Thanks to Serhii's suggestion, I found that the issue was due to "accept-encoding": "gzip, deflate, br": I accepted compressed sites but did not handle them in scrapy.

            Adding scrapy.downloadermiddlewares.httpcompression or simply removing the accept-encoding line fixes the issue.

            Install Scrapy on Windows Server 2019, running in a Docker container
            Asked 2021-Apr-29 at 09:50

            I want to install Scrapy on Windows Server 2019, running in a Docker container (please see here and here for the history of my installation).

            On my local Windows 10 machine I can run my Scrapy commands like so in Windows PowerShell (after simply starting Docker Desktop): scrapy crawl myscraper -o allobjects.json in folder C:\scrapy\my1stscraper\

            For Windows Server as recommended here I first installed Anaconda following these steps: https://docs.scrapy.org/en/latest/intro/install.html.

            I then opened the Anaconda prompt and typed conda install -c conda-forge scrapy in D:\Programs

            Answered 2021-Apr-27 at 15:14

            To run a containerised app, it must be installed in a container image first - you don't want to install any software on the host machine.

            For linux there are off-the-shelf container images for everything which is probably what your docker desktop environment was using; I see 1051 results on docker hub search for scrapy but none of them are windows containers.

            The full process of creating a windows container from scratch for an app is:

            • Get steps to manually install the app (scrapy and its dependencies) on Windows Server - ideally test in a virtualised environment so you can reset it cleanly
            • Convert all steps to a fully automatic powershell script (e.g. for conda, need to download the installer via wget, execute the installer etc.
            • Optionaly, test the powershell steps in an interactive container
              • docker run -it --isolation=process mcr.microsoft.com/windows/servercore:ltsc2019 powershell
              • This runs a windows container and gives you a shell to verify that your install script works
              • When you exit the shell the container is stopped
            • Create a Dockerfile
              • Use mcr.microsoft.com/windows/servercore:ltsc2019 as the base image via FROM
              • Use the RUN command for each line of your powershell script

            I tried installing scrapy on an existing windows Dockerfile that used conda / python 3.6, it threw error SettingsFrame has no attribute 'ENABLE_CONNECT_PROTOCOL' at a similar stage.

            However I tried again with miniconda and python 3.8, and was able to get scrapy running, here's the dockerfile:
