用brew升级八度时发生Tex错误

Question

I first installed octave through brew with the instruction on the office website. One day when I entered brew update && brew upgrade , octave started to upgrade but one error occurred said

You don't have a working TeX binary (tex) installed anywhere in your PATH, and texi2dvi cannot proceed without one. If you want to use this script, you'll need to install TeX (if you don't have it) or change your PATH or TEX environment variable (if you do). See the --help output for more details.

So I entered brew cask install mactex to install tex and added the Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin to the PATH, when I run tex , it correctly processed: terminal screenshot

Then I run brew upgrade but the same error occurred again.

I realized that the --without-docs argument may fix this problem but if I want to install docs (since I have already installed tex) what should I do?

Answer 1

I had similar problem while installing another program (not octave) and after looking around I found that I needed to install TeTex ( http://www.tug.org/teTeX/ ) or TexLive, however I decided to install TexLive because TeTex is not mantained anymore... For me it worked after installing Texlive on the basic configuration. You can follow the instructions over here:
