[Bug] 1.7.1 not support 1.6.0 script

[Kenith]

Hello All,

My spider is created by scrapy 1.6.0.
These days, the scrapy updated to 1.7.1, and we found that it cannot support the code build by 1.6.0.

Here is the error:

Traceback (most recent call last):
  File "/usr/bin/scrapy", line 6, in <module>
    from scrapy.cmdline import execute
  File "/usr/lib64/python2.7/site-packages/scrapy/cmdline.py", line 10, in <module>

  File "/usr/lib64/python2.7/site-packages/scrapy/utils/conf.py", line 4, in <module>
    import configparser
ImportError: No module named configparser

Would you please take time to check the issue?

Appreciate for your help in advance.

Thank you.

Hello @Kenith, this has been reported already at #3889
As I commented there, if you can install additional dependencies you can work around the issue by installing the backported version (https://pypi.org/project/configparser/).
If you don't mind, please consider closing this issue as it is a a duplicate of #3889. Thanks!
