Issue with running scrapy spider from script. #2473

tituskex · 2017-01-02T10:19:51Z

Hi, I'm trying to run scrapy from a script like this:

import scrapy
from scrapy.crawler import CrawlerProcess

class MySpider(scrapy.Spider):
    name = "basic"
    allowed_domains = ["web"]
    start_urls = ['http://www.example.com']

    def parse(self, response):
        l = ItemLoader(item=PropertiesItem(), response = response)
        l.add_xpath('title', '//h1[1]/text()')

        return l.load_item()
process = CrawlerProcess({
    'USER_AGENT': 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)'
})

process.crawl(MySpider)
process.start()

However, when I run this script I get the following error:

File "/Library/Python/2.7/site-packages/Twisted-16.7.0rc1-py2.7-macosx-10.11-
intel.egg/twisted/internet/_sslverify.py", line 38, in <module>
TLSVersion.TLSv1_1: SSL.OP_NO_TLSv1_1,
AttributeError: 'module' object has no attribute 'OP_NO_TLSv1_1'

Does anyone know how to fix this? Thanks in advance.

I would try to downgrade your twisted version from Twisted==16.7.0rc1 to Twisted==16.4.1. I got some weird errors too on the downloader part when I ran my Scrapy spiders with the same version you are running.

After, downgrading to the version I had(Twisted==16.4.1) things went back to working great again.

command: pip install Twisted==16.4.1
If you need sudo access then add it to your command.

#2479 This is related to this one as well.

redapple · 2017-01-24T14:19:22Z

@tituskex , did you manage to make it work?
did downgrading Twisted work?

pembeci · 2017-02-14T11:40:23Z

Downgrading Twisted worked for me too.

kmike · 2017-02-14T11:42:17Z

@pembeci what is your Scrapy version?

pembeci · 2017-02-14T13:30:12Z

@kmike The latest from pip install: 1.3.2. I am running on an old machine which is not upgraded for a while: Ubuntu 12.04 LTS - 32 bit
So may be that's why I needed to downgrade Twisted.

kmike · 2017-02-14T14:39:19Z

@pembeci what was the exception?
Hm, maybe it is caused by Twisted 17+ dropping pyOpenSSL < 0.16 support.

rmax · 2017-02-14T14:56:29Z

@pembeci I would recommend to use (mini)conda to have the latest releases without having to upgrade system libraries in old systems.

wzpan · 2017-03-01T09:35:55Z

+1 . Same problem with scrapy (1.3.2) and twisted (17.1.0) .

kmike · 2017-03-01T09:45:34Z

@wzpan what is your pyOpenSSL version?

Twisted dropped support for pyOpenSSL < 16.0.0 in Twisted 16.4.0 release (see http://twistedmatrix.com/trac/ticket/8441); in fact it worked for some time, but they recently removed some of the supporting code as well. Is upgrading it an option? You can check pyOpenSSL version by running python -c 'import OpenSSL; print(OpenSSL.version.__version__)'

wzpan · 2017-03-02T03:50:07Z

@kmike awesome! 👍
My pyOpenSSL version is 0.13.1. After upgrading it to 16.2.0, scrapy works like a charm!

Any help would be appreciated.

wzpan · 2017-03-02T08:01:06Z

@noprom Try doing these:

pip install --upgrade scrapy
pip install --upgrade twisted
pip install --upgrade pyopenssl

rapliandras · 2017-03-08T15:16:34Z

pip install Twisted==16.4.1

also solved mine, but tbh backwards incompatibility is a shame
twisted guys should really get this fixed

eegilbert · 2017-03-13T14:45:09Z

I couldn't even run scrapy by itself with out the SSL error until I downgraded Twisted from 17 to 16.4.1 per @rapliandras

redapple · 2017-03-13T15:29:37Z

For the record, we've released "packaging fix" versions that prevent Twisted>=17 getting installed, because branches 1.0.x, 1.1.x and 1.2.x only support Twisted<=16.6

v1.0.7
v1.1.4
v1.2.3

Master branch (and the recent v1.3.3) are compatible with Twisted 17+

redapple · 2017-03-27T11:25:39Z

So it seems that latest Twisted does require pyOpenSSL>=0.16, but provided you add the [tls] extra, as-in pip install twisted[tls].
Twisted 15.5 required pyOpenSSL>=0.13, but Twisted 16.6 requires pyOpenSSL>=0.16.
I think Scrapy should add the [tls] extra in its requirements, even if it will show a warning for Twisted<15 (the extra did not exist then). It should not prevent Scrapy from getting installed.

kmike · 2017-03-27T12:42:59Z

@redapple I haven't realized it is just a warning, not an error. If adding [tls] still allows to install Twisted then +1 to add it.

kmike · 2017-03-27T14:03:58Z

It seems that pip < 6.1.0 raises an error if extra requirement is unknown intead of showing a warning - see pypa/pip#2142. I'm not sure what happens if Twisted < 15.0 is already installed, user has pip < 6.1.0 (e.g. pip 1.5 is still popular), and runs pip install scrapy - does it work?

redapple · 2017-03-28T09:26:09Z

Good point @kmike . It does not work if one asks for Twisted<15:

$ pip install --upgrade 'pip<6.1.0'
$ pip install 'twisted<15'
$ pip install --upgrade 'twisted[tls]<15'
Successfully installed twisted-14.0.2
$ pip install --upgrade 'twisted[tls]<15'
You are using pip version 6.0.8, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

If we consider upgrades to latest Twisted, it works though, because latest Twisted has the extra:

Is it fair to say that installing and upgrading via pip with twisted[tls] in dependencies would work in this case? (assuming Twisted>=15 is available from the package index being used)
I may be missing something.

kmike · 2017-03-28T11:26:08Z

I was asking about a different case:

User already has Twisted < 15 installed (e.g. from system packages), but doesn't have Scrapy installed.
Then user runs pip install scrapy, without --upgrade or specifying a version.

It seems it can fail (I've execute this in a clean virtualenv):

redapple · 2017-03-28T11:36:58Z

Alright, so the best we can do until scrapy requires twisted[tls]>=15 is to document this in the faq perhaps. And maybe suggest either `pip install --upgrade scrapy` or downgrade Twisted. Thoughts ? Le 28 mars 2017 13:26, "Mikhail Korobov" <notifications@github.com> a écrit :

For the record, both debian jessie and ubuntu 14.04 use pip 1.5 and twisted < 15.0, so these baslines are affected.

Suggesting pip install -U scrapy is ok, but not always - this will upgrade requirements like pyOpenSSL or cryptography or lxml, and installation could fail (compiling may require too much RAM, or build dependencies may be absent). It may also fail after installation, at runtime - I recall upgrading scrapy this way on Ubuntu 14.04 without using virtualenv (with pip3 install --user); installation was successful, but then cryptography failed to load, seemingly because pyOpenSSL was not able to use OpenSSL version installed on Ubuntu 14.04.

kmike · 2017-03-28T11:53:24Z

What do you think about providing scrapy[tls] extra? After bumping requirements to Twisted[tls] >= 15.0 we can make it no-op, and before that users can run pip install scrapy[tls]. I'm not sure it is possible to have the same package both in install_requires and in extra_requires, but with a different version and extras (twisted) - it needs to be checked.

redapple · 2017-03-28T12:34:42Z

I am not very fond of introducing a "tls" extra at Scrapy level as well, as I think it could be hard to explain that it does not mean TLS support ON or OFF, when to use it etc. It's just a shame we cannot says something like twisted<15,twisted[tls]>=15 in dependencies.

kmike · 2017-03-28T14:06:06Z

Fair enough. I'm fine with documenting this in FAQ, or maybe in a new Troubleshooting section in Install docs ("got AttributeError: 'module' object has no attribute 'OP_NO_TLSv1_1' exception? This happens because Twisted dropped support for older pyOpenSSL versions. Either downgrade Twisted to ... or upgrade PyOpenSSL to 0.16+).

sunilsharma07 · 2017-04-06T09:13:00Z

Have tried to deal with a problem Just follow up step working fine
pip install -U pip
pip install --upgrade scrapy
pip install --upgrade twisted
pip install --upgrade pyopenssl

redapple · 2017-04-06T09:27:19Z

+1 for a new Troubleshooting section in Install docs. Could be hard to keep updated, but I believe we have some common cases in StackOverflow and here

EDIT: just thought I'd mention that I've also tried putting from OpenSSL import SSL in my main.py file .

In scrapy=1.5.0 still exist this problem, need install Twisted==16.4.1

…x the problem scrapy/scrapy#2473

Its initial content covers the workaround for scrapy#2473.

diehummel · 2019-01-31T17:15:38Z

Hi,
uninstall scrapy and twisted etc from pip2 and install it with pip3.
It works with twisted 18.9, scrapy 1.6 for me with pip3.6 on centos.
give it a try
you maybe need to adjust the path (enironment) from /usr/bin to /usr/local/bin

Its initial content covers the workaround for scrapy#2473.

wRAR · 2021-08-17T15:29:52Z

I wonder if it's still needed with modern Scrapy?

Gallaecio · 2021-08-18T09:59:15Z

We actually covered this in the documentation as part of #3517

But now I wonder if we should remove that from the documentation now, if this were not needed nowadays.
