ipopt on Mac for MPC project #1412

Closed thelukasssheee closed 5 years ago

thelukasssheee commented 5 years ago

Hey guys,

very frustrating issues while trying to install ipopt... tried all the hints and issues that were available on Slack and here in the issue report.

Install of ipopt is failing, because it always finds at some mount multiple formulae. What I do not get: even when I untap the doubled taps before install, brew seems to resurrect them, as shown below.

I'm working on MacOS 10.13.6 with XCode etc. installed. Until now, I was able to get all of the projects to work.

I'm basically stuck... Any hints or ideas?

Based on the above, I'd suggest trying to remove whichever brew tap you aren't trying to use - the able is for whatever reason including both brewsci and dpo, and brew isn't smart enough to just decide on one or the other.

The warning is because you brew tap two repositories And both of them has ipopt.

What you need to do are two steps: $ brew untap brewsci/science // because brewsci/science is not working (at least for me) $ brew install ipopt --with-openblas // now you only have ipopt in dpo, so the warning will be gone!

This should work!

I tried both... as mentioned above, at some later point during installation, brew is always resurrecting the taps which I actually untapped. What could have helped would have been to actually delete the doubled installation routines. Strange error....

I finally did bypass the issue with a Linux virtual machine. I setup the environment in less than an hour and my code was working instantly.

Thanks for your help though!
