scrapy: 'module' object has no attribute 'OP_SINGLE_ECDH_USE'

Question

I am new in scrapy, I create a sample project in scrapy and run the project. I got an error

AttributeError: \'module\' object has no attribute \'OP_SINGLE_         


        

Answer 1

I had a similar error, found that pyopenssl was not installed correctly

Simply did

sudo apt-get install libssl-dev

then

pip install pyopenssl --upgrade

scrapy scraped again
