"Could not import extension sage_autodoc"

[Joseph Hundley]

sage --docbuild <SOMETHING> html

produces many errors that look like this 

[tensor   ] Extension error:

[tensor   ] Could not import extension sage_autodoc (exception: cannot import name sage_formatargspec)

Build finished.  The built documents can be found in SAGEROOT/local/share/doc/sage/html/en/reference/tensor

(the only thing I see varying from one to the next is what is the instances of "tensor" in this example. 

No actual documentation is built. That is SAGEROOT/local/share/doc/sage/html/en/reference/tensor is empty.

Any idea what's going on?

You've presumably downgraded your Sage version by checking out some
older, pre-#20545 one.

You have to run 'make' after doing so (or in this case, './sage -b'
might be sufficient, but running 'make' is safer).
