I tried installing the tk GUI for Ubuntu ruby With the command:

But the command does not work. What can I do?

Answer

Hey I ran into this same thing recently while porting the Princeton Standard library to ruby tk standard_draw_tk

First make sure libaries are installed

sudo apt-get install tcl8.5-dev tk8.5-dev

Now you need to soft link the libaries

sudo ln -s /usr/lib/x86_64-linux-gnu/tcl8.5/tclConfig.sh /usr/lib/tclConfig.sh
sudo ln -s /usr/lib/x86_64-linux-gnu/tk8.5/tkConfig.sh /usr/lib/tkConfig.sh
sudo ln -s /usr/lib/x86_64-linux-gnu/libtcl8.5.so.0 /usr/lib/libtcl8.5.so.0
sudo ln -s /usr/lib/x86_64-linux-gnu/libtk8.5.so.0 /usr/lib/libtk8.5.so.0```

Now you can install the tk gem on linux

gem install tk
