problem installing py36-ipython on Mac OS Sierra 10.12.5

[lpagani91]

Hello,

I tried to install py36-ipython (python-3.6 is installed and working) but failed. The first time it failed (repeatedly) on the last dependency installation (py36-wcwidth).

Opening XCode, it asked me to update some features. I did. I reinstalled XQuartz behind, to be sure. I reinstalled Macports itself, selfupdated, and upgraded outdated then I tried to install py36-ipython again and it failed at the first dependency installation (py36-gnureadline)! while it did not before!!!

I am lost...

log file I was asked by the port install program to attach to this ticket

In the future, please fill in the Port field with the port that actually fails to build and Cc that port's maintainers (port info --maintainers py36-gnureadline), if any.

Please provide the output of port provides /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/six-1.10.0.dist-info command.

Replying to lpagani91:

Not sure to do it correctly (I am new to all this, sorry) :

sudo port provides /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/six-1.10.0.dist-info/ /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/six-1.10.0.dist-info is a directory

Ok. Please, provide output of port provides for one of the files from /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/six-1.10.0.dist-info directory.

It looks like you've installed six package (directly or undirectly) via sudo pip/easyinstall or sudo python setup.py install. And now that package interferes with MacPorts installation scripts.

I did not follow up immediately. Cleaning my macport install I stumbled against this problem again. I uninstalled python35 and python36 and reinstalled them. Both were OK. I installed py35-ipython (and its dependency py35-gnureadline) without problem but py36-gnureadline install still crashes :

there is no trace of six package in my Macports presently.

[jmroot (Joshua Root)]

Looks like first six then scipy had incorrect permissions on files they installed, which caused setuptools to fail as described upstream: ​https://github.com/pypa/setuptools/issues/617

Is this a problem with the current versions of those packages?

[jmroot (Joshua Root)]

No response; assuming fixed.
