The Amber CLI offers you a set of command line tools to create, generate, scaffold and run your projects quickly and simply.
Ensure you have the necessary dependencies:
Git: Use your platform specific package manager to install git
Crystal: Follow the instructions to get crystal
on this page:
NodeJS and Webpack: node
is an optional dependency and is used to compile JavaScript and other assets.
PostgreSQL: postgres
is a relational database server. Amber configures applications to use this database adapter by default, but you can switch to MySQL by passing the flag --database mysql
when creating a new application.
Once you have these dependencies, You can build the amber
tool from source:
Download and install amber
NOTE: At the time of this writing, v1.4.1 is the current stable release, but you should use the most recent tag in place of that.
If you run into an issue on compilation regarding Unhandled exception in spawn: fork: Cannot allocate memory
it means you don't have enough memory. This can easily be solved by adding a swapfile.
Currently, the only method to install on Debian based distros is to compile from source.
These are necessary to compile the CLI:
sudo apt-get install build-essential libreadline-dev libsqlite3-dev libpq-dev libmysqlclient-dev libssl-dev libyaml-dev
sudo yum groupinstall development tools
sudo yum install readline-devel sqlite-devel openssl-devel libyaml-devel gc-devel libevent-devel
yaourt -S amber
You should now be able to run amber
in the command line.
Installing Amber with these package managers also installs Crystal.
Homebrew
MacPorts
Known problems while trying to build Amber from source on macOS:
If you see linker problems, such as ld: library not found for -lssl (this usually means you need to install the development package for libssl)
, you may need to set some (or all) of those environment variables:
Install the CLI from . Dependencies are automatically installed.
