There's a lot of errors installing scrapy under Windows, and I'm sending out the steps I've made for more people to refer to.
First, go directly to the Scrapy website under the document Installation Guide under installing Scrapy:
Https://doc.scrapy.org/en/1.2/intro/install.html
You can see the packages on which the scrapy is installed.
Parsel, W3lib, cryptography, Pyopenssl These can be installed directly using the PIP command. Such as:
Pip Install Parsel
lxml and twisted use PIP to install the error.
These two packages can be downloaded in the following Web site WHL file, after installation.

Note Download When you want to select your own operating system and the number of Python software bits corresponding to download
Dependency packages can be installed with the PIP command after the installation is complete scrapy
Waiting to be done shows successfully.
At this point, scrapy installation is complete, you can do what you want to do
