ADDITIONAL ACTIONS ARE REQUIRED!
--------------------------------
1 - If you did not have Node.js and/or NVM installed previous to this please open a new shell/terminal now!
(!) Not doing so will prevent 'nvm' or 'node' commands from functioning!
2 - If this is the first time you've installed ENiGMA½, you now need to generate a minimal configuration:
2017-01-30 02:55:48 +00:00
cd ${ENIGMA_INSTALL_DIR}
2017-06-01 21:39:26 +00:00
./oputil.js config new
2017-01-30 02:55:48 +00:00
3 - Additionally, a minimum of the following support binaires are recommended:
2017-01-30 02:55:48 +00:00
7zip: Archive support
Debian/Ubuntu : apt-get install p7zip
CentOS : yum install p7zip
Lha: Archive support
Debian/Ubuntu : apt-get install lhasa
2017-01-31 04:54:00 +00:00
Arj: Archive support
Debian/Ubuntu : apt-get install arj
2017-01-30 02:55:48 +00:00
sz/rz: Various X/Y/Z modem support
Debian/Ubuntu : apt-get install lrzsz
CentOS : yum install lrzsz
See docs for more information including other useful binaries!
