Mac OS X 10.9 "Unknown Terminal Type" error after installing R module

[pjames....@gmail.com]

Currently running OS X Mavericks, and ran the following command to install conda for R:

conda install -c asmeurer r

Has anyone else gotten an "Unknown Terminal Type" error in their Terminals after installing? I managed to track down the error to the ncurses module that was installed as a linked dependency, and the problem went away after removing it.

What is your TERM environment variable?

Currently set to "xterm". After installing the r module, it was changed to "xterm-256color". I tried changing it back using the following methods: 

1. Via export command in Bash (first in .profile, then .bashrc)
2. "Declare terminal as..." setting in Terminal->Preferences
   

Both methods yielded the correct terminal type when typing in "echo $TERM", but running a related command such as "reset" gave the "Unknown terminal type ____" error, no matter what type it was set to. Once I ran "conda remove ncurses" (without removing any other linked dependencies for r), the problem went away.

I just ran into this by doing `conda install -c r r-irkernel`, but it's easily reproducible with just:

    conda install ncurses
    hash -r
    tput

I don't think it's changing the TERM value (mine has been xterm-256color without issue for a long time), but somehow the ncurses package installs commands (tput, tset, etc.) that don't actually work. As above, `conda remove ncurses` after the fact fixes the immediate problem, but I'm not sure what it breaks, if anything. I presume the dependency is in there for a reason.

So I'm guessing this is a problem in the ncurses conda package not being able to find its own terminfo, but I don't know enough about how that stuff works. I do see the terminfo tree in $PREFIX/share/terminfo.

Try the ncurses package from my channel (or the r channel; should be the same). I remember making some fixes to the recipe and rebuilding it (particularly, adding --enable-termcap when building). I don't know if this is the same issue. tput does work on my computer though (with my ncurses package).

This fixed the problem for me.

So how did this end up in the distro?

--terminfo)

echo "/Users/aaronmeurer/anaconda/envs/_build_placehold_placehold_placehold_placehold_/share/terminfo"

--terminfo-dirs)

echo "/Users/aaronmeurer/anaconda/envs/_build_placehold_placehold_placehold_placehold_/share/terminfo"

  --terminfo         echos the \$TERMINFO terminfo database path

  --terminfo-dirs    echos the \$TERMINFO_DIRS directory list

  infocmp: couldn't open terminfo file /Users/aaronmeurer/anaconda/envs/_build_placehold_placehold_placehold_placehold_/share/terminfo/78/xterm.

Are you seeing this with the latest build of ncurses (build 1)? What
is your "conda list ncurses"?

[john sterling]

conda list ncurses
# packages in environment at /Users/jhs/anaconda:

Run

conda install -c r ncurses

(it looks like I only had the latest build on my channel, not also the
r channel, so that may explain why you didn't have it).

Thanks Aaron, that got it.
