I am working on Scrapy 0.20 with Python 2.7. I found PyCharm has a good Python debugger. I want to test my Scrapy spiders using it. Anyone knows how to do that please?

推荐答案

scrapy 命令是一个 Python 脚本，这意味着您可以从 PyCharm 内部启动它.

The scrapy command is a python script which means you can start it from inside PyCharm.

当你检查scrapy二进制文件(which scrapy)时，你会注意到这实际上是一个python脚本:

When you examine the scrapy binary (which scrapy) you will notice that this is actually a python script:

#!/usr/bin/python

from scrapy.cmdline import execute
execute()

这意味着像这样的命令scrapy crawl IcecatCrawler 也可以这样执行: python/Library/Python/2.7/site-packages/scrapy/cmdline.py crawl IcecatCrawler

This means that a command like scrapy crawl IcecatCrawler can also be executed like this: python /Library/Python/2.7/site-packages/scrapy/cmdline.py crawl IcecatCrawler

尝试找到scrapy.cmdline 包.就我而言，位置在这里:/Library/Python/2.7/site-packages/scrapy/cmdline.py

Try to find the scrapy.cmdline package. In my case the location was here: /Library/Python/2.7/site-packages/scrapy/cmdline.py

使用该脚本作为脚本在 PyCharm 中创建运行/调试配置.用scrapy 命令和spider 填充脚本参数.在这种情况下 crawl IcecatCrawler.

Create a run/debug configuration inside PyCharm with that script as script. Fill the script parameters with the scrapy command and spider. In this case crawl IcecatCrawler.

像这样:

将断点放在爬行代码中的任何位置，它应该可以工作™.

Put your breakpoints anywhere in your crawling code and it should work™.
