It's recommended to install Graphics Magick. If it's not installed, the library will automagically try to install lwip
by compiling the C/C++ stuff.
# Ubuntu
$ sudo apt-get install graphicsmagick
# Fedora
$ sudo dnf install GraphicsMagick
# CentOS / RHEL
$ sudo yum install --enablerepo epel GraphicsMagick
# OS X
$ brew install graphicsmagick
# Windows users can install the binaries from http://www.graphicsmagick.org/
...or using the command line:
# Chocolatey (package manager for Windows)
# (Restart of cmd/PowerShell is required)
$ choco install graphicsmagick
Then, you can install this package:
$ npm i --save image-to-ascii
