Terminal doesn't print colors

Question

My Antergos terminal doesn’t show me any colors when executing scripts. I have a fresh instalation, with no tweaks. I have zsh and oh-my-zsh, but the configurations are the default ones.

You can see that all the output is white, it should be colorful:

This happen when I install programs, blanks spaces are text:

I tried to customize the profiles, with no success, I tried a fresh instalation with the same ISO in my laptop with no problems, but I don't want to reinstall Antergos in this machine.

tput colors outputs 256

Answer 1

The problem appears to have been fixed, but the cause was a hardcoded check for the TERM environment variable equal to xterm. If (as indicated in the question) you had xterm-256color, then the check would fail.

You can see one of the diff's which is part of the change to fix this problem in the git repository, in this chunk of deleted lines:

-    /**
-     * Returns whether we are a terminal and have colour capabilities
-     *
-     * @return bool
-     */
-    private function isColorTerminal()
-    {
-        if (function_exists('posix_isatty')) {
-            $result = posix_isatty(STDOUT);
-        } else {
-            // See if STDOUT is a character device (S_IFCHR)
-            $stat = fstat(STDOUT);
-            $result = ($stat['mode'] & 0170000) === 0020000;
-        }
-
-        if (defined('PHP_WINDOWS_VERSION_BUILD') && $result) {
-            $result = false !== getenv('ANSICON')
-            || 'ON' === getenv('ConEmuANSI')
-            || 'xterm' === getenv('TERM');
-        }
-
-        return $result;
-    }
