Could you share the full traceback, please?

Having the same problem with the 0.17, looks like 0.13.1 regression (1, 2). Pinning 0.16 fixes this.

Pinning 0.16 fixes this.

I confirm. pip3 install docutils==0.16 sphinx ... worked for me. Thanks @zmey3301

[tk0miya]

Thank you for the info. It seems the error happened inside the recommonmark extension. I guess this is a bug of it. The tab_width entry is needed for the settings_spec of the recommonmark parser. Please report this into their project. Thanks,
