I have followed the website of CGAL. It told me that I could install it by using the command
brew install cgal-qt5.
But I have received the following error message:
Updating Homebrew...
Error: No available formula with the name "cgal-qt"
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
git -C "$(brew --repo homebrew/core)" fetch --unshallow
Error: No previously deleted formula found.
==> Searching for similarity named formulae...
Error: No similarly named formula found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in tabs.
And when I run the example draw_triangulation_2.cpp, it has a fatal error:
'CGAL/Qt/Basic_viewer_qt.h' file not found
I guess this result is generated because of the lack of cgal-qt5, but I cannot fix it. I hope someone can help me. Thanks.
Actually the doc here is wrong. The PR for this was never accepted, and the doc about cgal on brew was published before the cancellation of the PR. On brew, you can install cgal with brew install cgal but you won't have the GUI elements in that package until this PR is integrated.

I am encoutering two kinds of issues while trying to install a package called Boltztrap2.
1) Trying to install Boltztrap2 using 'pip3'. However, when I punch in the command, the process goes smoothly for a while and then spits out an error :
BoltzTraP2/sphere/frontend.cpp:32:20: fatal error: Python.h: No such file or directory
#include "Python.h"
^
compilation terminated.
error: command 'gcc' failed with exit status 1
I did some troubleshooting and found out that it is just a path issue - I confirmed this by typing 'locate Python.h'. However, I don't get how to manually incorporate this change since the 'pip3' command that I use downloads the program and compiles it automatically. I don't seem to have access to change any scripts, or rather I do not know how to, since I'm kind of new to all this.
PS: I do not have sudo access.
2) Trying to install Boltztrap2 by manually compiling the python setup file: This seems to work fine until the system spits out an error saying:
Error:numpy is not installed.
PS: Again, I do not have sudo access.
I would be very glad if someone could help me install this package through either method. I just want to get the software to work. Thanks in advance for any assistance.
python3 -m pip install --upgrade pip
pip3 install numpy
Check if you can upgrade pip?
If that works then you can pip install numpy.
I have just installed gst-browser (VisualGST) through the Canonical Ubuntu repositories, so I tried to start VisualGST by running gst-browser on the command line. However, I am immediately greeted with an error:

What is the cause and meaning of the error, and how can I start VisualGST properly?
GNU Smalltalk version: 3.2.5
EDIT:
This appears to be a known issue. There's a bug report from 2012 on Launchpad: Smalltalk browser does not launch.
This appears to to be "known" issue. As I previously guessed the issue was in libraries link(age).
You can solve your issue either by installing - libgtk2.0-dev.
You can find the whole conversation here. Here is an excerpt:
Digging a bit further, I found that the module "gst-gtk-3.2.92.so" is
linked against "libgtk-x11-2.0.so", which is (now?) only provided by
package: gtk2-devel.
Your second option is to compile it from source. On Fedora 27 (again from the discussion and link above):
I'm on Fedora 27 and after a fresh install this gave me a working build:
sudo dnf install gcc git automake bison flex libtool libtool-ltdl-devel libffi-devel libsigsegv-devel cairo-devel gtk2-devel texinfo
git clone git://git.sv.gnu.org/smalltalk.git
cd smalltalk
autoreconf -vi ./configure make
sudo make install
-----------------------
For future referece you can find testing gst-browser gist.
I'm currently trying to install scrapy when I encountered my first error:
ERROR conda.core.link:_execute_actions(337): An error occurred while installing package 'conda-forge::automat-0.7.0-py_1'.
CondaError: Cannot link a source that does not exist. D:\ProgramFiles\Python\Scripts\conda.exe
Running conda clean --packages may resolve your problem.
Attempting to roll back.
CondaError: Cannot link a source that does not exist. D:\ProgramFiles\Python\Scripts\conda.exe
Running conda clean --packages may resolve your problem.
I researched this error and followed the advice on this link:
My issues were largely similar to his until I reached the comment which advised me to run conda update -n base conda.
When I ran this code, I encountered my next error:
CondaEnvironmentNotFoundError: Could not find environment: base .
You can list all discoverable environments with conda info --envs.
Kindly advice if my steps taken were appropriate and how can I fix this issue.
The weird thing is I installed scrapy before, and these errors occurred after I recently re-installed Anaconda.
I'm not sure what other info you might require to better understand the situation. Do let me know and I will assist promptly.
Thank You
Try the conda install scrapy channel instead of the conda-forge channel.
To understand the difference between these two channels please read the answer of the following question Should conda, or conda-forge be used for Python environments?
I'm trying to install HomeBrew on my iMac running OSX 10.11.1 El Capitan.
On the HomeBrew home page there is a short script in Ruby to paste into Terminal. When I did this, I got an error message as pasted below:
chown: King_Bud: illegal user name Failed during: /usr/bin/sudo
/usr/sbin/chown King_Bud /usr/local/. /usr/local/bin /usr/local/lib
/usr/local/share /usr/local/share/man /usr/local/share/man/man1
/usr/local/share/doc
Based on the above message, I ran the first aid program in disk utilities and no permission errors were identified. But the above error code suggests some type of permission problem.
I see there was a post 2 years ago describing a similar error message but it sounds like this was occurring after HomeBrew was already installed, and pertained to installing new packages rather than the HomeBrew program itself. How to fix homebrew permissions?
Any thoughts about how to resolve the "illegal user name" problem would be appreciated.
I figured out the problem.
the chown error message was being created because my $USER environmental variable in my bash_profile was not matching the name of my logged-in user name as identified in Finder.
When I went into my bash_profile and edited the USER environmental variable so that $USER was the same as my logged-in user name in Finder, then I was able to successfully install HomeBrew using the pasted command from the HomeBrew home page.
Hopefully this posting will be helpful for anyone in the future who gets a similar error message while trying to install HomeBrew.
I tried to install the latest ASP.NET on Mac OS X Yosemite according to the instructions on github.
I already have Homebrew, so this step worked fine:
brew tap aspnet/k
However, on the next step, brew install kvm, I get errors:
$ brew install kvm
==> Installing kvm dependency: mono
==> Downloading http://download.mono-project.com/sources/mono/mono-3.8.0.tar.bz2
Already downloaded: /Library/Caches/Homebrew/mono-3.8.0.tar.bz2

Error: Failed to download resource "mono--monolite"

Note: the first time I ran this, I got a slightly different message when mono-3.8.0 installed successfully.
David Fowler was quick to answer my question on Twitter and suggested a brew update (Thanks David!) but I got this:
$ brew update
error: Your local changes to the following files would be overwritten by merge:
Library/Formula/google-perftools.rb
Please, commit your changes or stash them before you can merge.
Aborting
Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master
At this point, it seems like it's a Homebrew problem. What am I doing wrong?
Update: sorry, I was an idiot. As suggested by agua from mars and David Folwer, I fixed the issue as follows:
cd /usr/local/Library/Formula/
git reset HEAD google-perftools.rb
git checkout google-perftools.rb
brew update
brew install kvm
And this time kvm installed OK. Then I just added the line source /usr/local/Cellar/kvm/1.0.0-beta1/libexec/kvm.sh to my .bash_profile
As we discuss in comments.
You have a git conflict on this file Library/Formula/google-perftools.rb.
you should undo your change:
git checkout -- Library/Formula/google-perftools.rb
or doing a git reset.
And update brew again
