Python is 3.5.2
install PIP install scrapy today    To install
Microsoft Visual C + + 14.0 is required

Later, the solution was to use files to install

1. Download the scrapy installation file

2. Install this using the command PIP install wheel

3. Switch CMD to the directory where the scrapy file is located and install it by PIP install *********************************************************

4. You can use PIP install scrape to check whether the installation is successful
