Failed to set default locale

Probably the system locale preferences is not configured properly, try to re-configure the locale preferences: Uncomment the locales in /etc/locale.gen to your locale (e.g. EN)
#en_US.UTF-8 to en_US.UTF-8
Then generate the locale with:
Set locale preferences in /etc/locale.conf and possibly $HOME/.config/locale.conf to your locale (e.g. EN): (case sensitive) echo LANG=en_US.UTF-8 > /etc/locale.conf Warning: The locale configuration is case sensitive if any characters mistyped it will affect the locale configuration, reboot to take effects. If above steps doesn't work and you've still received "Failed to set default locale" try this alternative steps: Edit the .bashrc file using a text editor such as nano:
sudo nano ~/.bashrc
Then add following (change it to your locale e.g. EN):
export LANG=en_US.UTF-8
export LC_MESSAGES="C"
export LC_ALL=en_US.UTF-8...

Failed to find a command (Command not found)

Command not found means the command that yaourt need to compile the package is missing, you can install the missing command: (e.g. automake/aclocal: command not found)
pacman -S automake
If you can't find the missing command to install, you can find the missing package file using pacman.
pacman -Fs missing-file
Or search the package name.
pacman -Ss package-name
