Install ExtJS

cd
wget -c http://cdn.sencha.com/cmd/6.5.1/no-jre/SenchaCmd-6.5.1-linux-amd64.sh.zip
unzip SenchaCmd-6.5.1-linux-amd64.sh.zip
# USE THE GRAPHIC INSTALL!
# the command-line one '-q -dir ~/sencha/senchacmd' appears that does not work (it loose CSS files)
bash SenchaCmd-6.5.1.240-linux-amd64.sh
exit # reopen the bash to get the 'sencha' command in the env
