使用PyCharm运行scrapy - 调试工作但Run不起作用

Question

I met a very strange issue, running Scrapy with PyCharm:
With the exact same configuration, Debug works, but Run with PyCharm does NOT work.

• Windows 10
• PyCharm 2016.3.3
• Scrapy 1.3.3
• Python 3.6.0

Configuration: PyCharm Edit Configuration Page

When I attempt to debug scrapy, it works perfectly. When I attempt to run scrapy, I get below error:

C:\Users\baib2\AppData\Local\Programs\Python\Python36\python.exe 
C:/Users/baib2/AppData/Local/Programs/Python/Python36/Lib/site-packages/scrapy/cmdline.py crawl scenelist_spider

    import http.client
ModuleNotFoundError: No module named 'http.client'

Process finished with exit code 1

No need to attach any code because even running the command:

python3.exe C:\\Users\\baib2\\AppData\\Local\\Programs\\Python\\Python36\\Lib\\site-packages\\scrapy\\cmdline.py

will produce the same error.

I've checked my sys.path , comparing with run, debug has 1 more path:

'C:\\Program Files (x86)\\JetBrains\\PyCharm 2016.3.3\\helpers\\pydev'

And I really don't think this shall make any difference.

Hope someone can take a look, thanks!

Answer 1

菜单运行>编辑配置启用复选框“以后显示命令行”这对我有帮助

Answer 2

如果您使用的是新版本的PyCharm， Show Command line afterward不再可用，则Run with Python console可解决此问题。

Answer 3

I've also spent some time tracking a similar problem.

My issue was that I have a local module named http which of course does not submodule called client . Another similar issue is described here .

The solution is to change Working directory for this test invocation via Edit configurations .
