nano error: Error opening terminal: xterm-256color

问题:

After the installation of OSX Lion, I tried to:

nano /etc/apt/sources.list

But I get this error:

Error opening terminal: xterm-256color

If I try to switch terminal.app preferences to open terminal windows in "xterm color" instead of xterm-256color everything works fine.

What's happening?

回答1:

On Red Hat this worked for me:

export TERM=xterm

回答2:

After upgrading to OSX Lion, I started getting this error on certain (Debian/Ubuntu) servers. The fix is simply to install the “ncurses-term” package which provides the file /usr/share/terminfo/x/xterm-256color.

This worked for me on a Ubuntu server, via Erik Osterman.

回答3:

I can confirm this is a terminfo issue. This is what worked for me. SSH in to the remote machine and run

 sudo apt-get install ncurses-term

Boom. Problem solved.

回答4:

I, too, have this problem on an older Mac that I upgraded to Lion.

Before reading the terminfo tip, I was able to get vi and less working by doing "export TERM=xterm".

After reading the tip, I grabbed /usr/share/terminfo from a newer Mac that has fresh install of Lion and does not exhibit this problem.

Now, even though echo $TERM still yields xterm-256color, vi and less now work fine.

I had this problem connecting to http://sdf.org through Mac OS X Lion. I changed under Terminal Preferences (⌘+,) > Advanced pane, Declare Terminal as to VT-100.

I also marked Delete Sends Ctrl-H because this Mac connection was confusing zsh.

It appears to be working for my use case.

回答6:

somehow and sometimes "terminfo" folder comes corrupted after a fresh installation. i don't know why, but the problem can be solved in this way:

1. Download Lion Installer from the App Store
2. Download unpkg: http://www.macupdate.com/app/mac/16357/unpkg
3. Open Lion Installer app in Finder (Right click -> Show Package
Contents)
4. Open InstallESD.dmg (under SharedSupport)
5. Unpack BSD.pkg with unpkg (Located under Packages)   Term info
will be located in the new BSD folder in /usr/share/terminfo

hope it helps.

回答7:

I hear that this can be fixed by overwriting your /usr/share/terminfo with one from the computer of somebody with a working install of Lion. I can't confirm whether this works or not, and unfortunately I haven't upgraded yet, so I can't provide you with that file.

回答8:

You can add the following in your .bashrc

if [ "$TERM" = xterm ]; then TERM=xterm-256color; fi

回答9:

1. edit your .bash_profile file

   vim .bash_profile

2. commnet

   #export TERM=xterm-256color

3. add this

   export TERMINFO=/usr/share/terminfo

   export TERM=xterm-basic

   to your .bash_profile

4. finally

   run:

   source .bash_profile

Mine was quite a unique case but this could help someone. On Android I tried to copy nano from my termux binary folder to /system/xbin. Placed all the library dependencies in /system/lib and got this error. The libncurses.so.6 file I copied from termux had it's TERMINFO file still pointed to /data/data/com.termux/files/usr/share/terminfo

View pointed path with command

strings path-to-libncurses.so | grep /terminfo

To fix either make the termux terminfo dir and subdirs readable and executable by the nano user or copy the terminfo folder somewhere else and use a hexeditor to modify the plain text path in the shared library file.
