Instructions for installing SAGE from source on MacOS are hard to follow.
I am trying to follow the instructions at https://github.com/sagemath/sage/#readme
I started by selecting a mirror and downloading sage-10.0.tar.gz.
As is customary, it ended up in my "Downloads" folder.
The next instruction says "After downloading the source tarball sage-10.0.tar.gz into ~/sage/" -- I'm not sure what this means -- by "downloading into ~/sage/" do the instructions really mean "drag and drop"?
I successfully dragged and dropped it into ~/sage/, but when I try the next step, it fails to expand the archive.
I tried the following:
$ cd ~/sage/
$ tar xf sage-10.0.tar.gz # adapt 10.0;
the terminal responds as follows:
tar: #: Not found in archive
tar: adapt: Not found in archive
tar: 10.0: Not found in archive
tar: Error exit delayed from previous errors.
Should I just expand the archive by opening the "sage" folder in the finder and double clicking on the age-10.0.tar.gz file?
Or is it critical that I expand it using the terminal commands shown in the ReadMe?
It is not critical to use the terminal, in macOS you can expand the archive from Finder.
Thanks for your help. I do wish the instructions were simpler, and also I wonder why the command failed to execute in the terminal window.
Did it fail? It may have unpacked the tar file and then run into errors (for reasons I don't understand) after that. One confusing part is that
#is a comment symbol, and it and anything after it should be ignored, so I don't know what went wrong with that. You should be able to dotar xf sage-10.0.tar.gz(without the comment) from the terminal.Yeah, I realized that was just a comment symbol earlier today which was kind of embarassing.
I have unpacked sage-10.0.tar.gz within the folder ~/sage/ using a double click in finder.
I just now tried to do this step:
"Some Homebrew packages are installed “keg-only,” meaning that they are not available in standard paths. To make them accessible when building Sage, run
source SAGE_ROOT/.homebrew-build-env"
Here is what I typed, and here is the terminal output:
stephensalser@Stephens-MBP-2 / % source ~/sage/.homebrew-build-env source: no such file or directory: /Users/stephensalser/sage/.homebrew-build-env
I am trying so hard to follow the instruction as listed on SAGEMATH, but almost every listed command runs into problems for me.
SAGE_ROOT is now
~/sage/sage-10.0/or something along those lines: it's the directory whereREADME.mdis, for example. So you need to dosource ~/sage/sage-10.0/.homebrew-build-env.
