I am following the procedure on "A Programmer’s Guide to Ethereum and Serpent" (https://mc2-umd.github.io/ethereumlab/docs/serpent_tutorial.pdf) and when I get to installing Serpent I get the error:
$ python setup.py install --user
Traceback (most recent call last):
File "setup.py", line 8, in
flag for flag in opt.split() if flag != '-Wstrict-prototypes'
AttributeError: 'NoneType' object has no attribute 'split'
Any ideas? I am on Windows 10.
