During the installation process of devstack in Ubuntu using stack.sh , am having the error mentioned in ** below. Kindly share the solution if anyone figured out the way to do so.

Getting the same issue as well. Looks like something broke upstream.

I was able to bypass the error by commenting out the else fragment in py36compat.py

It should help you run the stack.sh to completion but I don't know if it is wise to do this.

Just wanted to update everyone, the upstream issue has been resolved. No need to go through these steps anymore. Just update your devstack code base.

@HassanPasha: thank you my friend, your solution work for me.

To elaborate: Find that py36compat.py file, in my case was

sudo vim /usr/local/lib/python2.7/dist-packages/setuptools/command/py36compat.py

Scroll down to the ELSE statement (Line #111), comment out everything from line #111 -> #115

Save, quit, ./unstack.sh, reboot, sudo su stack, cd to whatever, ./stack.sh

Voila.

Result

Not completely associated with the installation of DevStack but I've come across this thread while looking for the same error in the installation of another python module: django-compressor.

As stated above the problem lies in line #111 in py36compat.py file that is hidden somewhere in /lib/pythonX.X/dist-packages/setuptools/command/ directory. This part of code:

            else:
                # a (dirname, filenames) tuple
                dirname, filenames = item
                for f in filenames:
                    f = convert_path(f)
                    if os.path.isfile(f):
                        self.filelist.append(f)

should be replaced with something like this:

            else:
                filenames = item._files
                for f in filenames:
                    f = convert_path(f)
                    if os.path.isfile(f):
                        self.filelist.append(f)

Most likely this will be fixed by the developers soon, but maybe someone will benefit.
