[Python] [Scrapy framework] installation of Python3 Scrapy, scrapypython3
1. Method (only pip installation is introduced)

PS. It is unclear that pip (easy_install) can be Baidu or left a message.

Cmd command:

(Pip can be used directly, instead of jumping to the pip.exe directory because the directory is added to the Path environment variable)

Advantages of pip install:

Easy to install

Install scrapy and dependency packages

Package consistency can be ensured

2. Possible Problems

Some cannot be installed automatically upon installation:

The sub-extension package 'twisted. test. raiser 'cannot be installed automatically because VC ++ 14.0 is required.

3. Solution

When pip cannot be installed, manually install it, and then re-install pip scrapy until the installation is complete.

Manual extension support package:

Http://www.lfd.uci.edu /~ Gohlke/pythonlibs/# lxml

(You must select the corresponding package of your version)

(Go to python in cmd to view your version)

For example:

Display the 64-bit python 3.5 version

The supported libraries that I need to download:

After the installation is complete, check whether the scrapy framework is successfully installed:

The scrapy package is successfully imported, which generally indicates a problem with wood ~~

4. Postscript

"I hope everyone can install the scrapy framework smoothly.
