<p dir="auto">You need first "pip install incremental" due to a misspelling in the lines for the installation of dependencies.</p>
<p dir="auto">sudo pip3 install Scrapy -i <a href="https://pypi.douban.com/simple" rel="nofollow">https://pypi.douban.com/simple</a><br>
Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-s3504tu6/Twisted/</p>
<p dir="auto">so I use sudo pip3 install Scrapy -i <a href="https://pypi.douban.com/simple" rel="nofollow">https://pypi.douban.com/simple</a> but failed again.<br>
Please give me some advices, Thank you so much</p>
