Installation
That feeling you get when that right tool did all the work
The Amber CLI offers you a set of command line tools to create, generate, scaffold and run your projects quickly and simply.
Linux
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: Crystal InstallationNodeJS 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:
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.
sudo apt-get install libreadline-dev libsqlite3-dev libpq-dev libmysqlclient-dev libssl-dev libyaml-dev libpcre3-dev libevent-dev
git clone https://github.com/amberframework/amber.git
cd amber
git checkout v1.4.1
shards install
make
sudo make install
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.
sudo dd if=/dev/zero of=/swapfile bs=2k count=1024k
sudo mkswap /swapfile
sudo chmod 600 /swapfile
sudo swapon /swapfile
For Debian & Ubuntu
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
For RedHat & CentOS
sudo yum groupinstall development tools
sudo yum install readline-devel sqlite-devel openssl-devel libyaml-devel gc-devel libevent-devel
For ArchLinux & derivates
Install the CLI from AUR package. Dependencies are automatically installed.
yaourt -S amber
You should now be able to run amber
in the command line.
macOS
Installing Amber with these package managers also installs Crystal.
Homebrew
brew tap amberframework/amber brew install amber
MacPorts
sudo port selfupdate sudo port install amber
From source
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:export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig" export LDFLAGS="-L/usr/local/opt/openssl/lib" export CPPFLAGS="-I/usr/local/opt/openssl/include"
