Install packages:

sudo apt-get update
sudo apt-get install -y git-core python2.7-dev curl libfontconfig1-dev libc6 libgc-dev ocaml make xdg-utils libpq-dev \
  postgresql-client libav-tools python-pip fluidsynth graphicsmagick sox libsox-fmt-mp3 s3cmd nodejs npm libjpeg-dev redis-tools

Install core NPM packages

sudo npm install -g bower grunt-cli cordova protractor

Install HaXe


haxelib setup
haxelib install lime
haxelib run lime setup
# ln -s hxMath.h hxMath.h.h # In the right directory

Docker setup

sudo apt-get install
sudo groupadd docker
sudo usermod -aG docker macobo # replace with own username
# log out and in again

Download Docker files

docker pull redis
docker pull postgres

One last bit of configuration

echo "" | sudo tee --append /etc/hosts

Internal setup

Setup: Clone repo:

git clone https://[USERNAME]
cd guitar-teacher-frontend
# clone mms-haxe into guitar-teacher-frontend/haxe/
git clone https://[USERNAME] haxe

Install pip packages

sudo pip install -r matchmysound/requirements.txt

Install bower packages

cd matchmysound
bower install

Install node (build) packages

cd grunt
npm install

Set up DB (need to have ./ start db running in other terminal)

./ target matchmysound
# ./ start db # in another terminal or with &
./ db:create
./ db:sync

Start up the environment (separate windows)

./ start db redis api celery
./ start client

If client isn't acting up, then `python` should be sufficient!

If you see ENOSPC error, it is a problem with too many inotify watches. Solution:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

if you see sslwrap error, it is a gevent thing. 1.0.2 fixes it for Python 2.7.9 but if you have 2.7.8 that has the bug backported into it, just go to /usr/local/lib/python2.7/dist-packages/gevent/ and change PYGTE279 to True.

E2E Tests

Install Selenium browser drivers

sudo webdriver-manager update 

If it still complains about not finding them, you need to set the local npm to use the global protractor

 cd grunt/node_modules; rm -rf protractor; ln -s /usr/local/lib/node_modules/protractor protractor


Needed to get exercise creation working. Firstly:

 git clone

Then do "Install dependencies" and "Compiling the code" at:

For Mac (OSX): (loosely based on

Download Qt installer and use it to install Qt 5.4 (anything later won't work). Then:

brew install libogg libsndfile libvorbis pkg-config portaudio jack lame cmake git
cd MuseScore
make -f Makefile.osx clean
make -f Makefile.osx
make -f Makefile.osx install

then copy mscore from MuseScore/applebuild directory to "Applications" (as you normally install stuff on OSX) And then create a symlink so it could be used from commandline with:

ln -s /Applications/ /usr/local/bin/mscore

Editor (sublime)

Under Project - edit project, set

   "settings": {
       "expand_tabs_on_save": true,
       "trim_trailing_white_space_on_save": true


  • Index project using search in ctrl-shift-p
  • goto definition using ctrl+win+alt+l
  • jump to definition win+ctrl+l

Set user configuration to ignore temporary dirs - Preferences - Package Settings - AngularJS - Settings - User


Install Anaconda for python linting, goodies

Set user configuration in Anaconda to set max length a bit higher (note that you should still strive for 80)

   "pep8_max_line_length": 100

Set Anaconda User Key bindings

   {"command": "anaconda_goto", "keys": ["super+ctrl+alt+l"]},
   {"command": "anaconda_find_usages", "keys": ["super+alt+d"]},
   {"command": "anaconda_doc", "keys": ["alt+d"]},
   {"command": "anaconda_auto_format", "keys": ["super+a"]},
   {"command": "anaconda_goto", "keys": ["g", "d"],
           { "key": "selector", "operator": "equal", "operand": "source.python" },
           { "key": "setting.command_mode", "operand": true },
           { "key": "setting.is_widget", "operand": false }


  • goto definition using ctrl+win+alt+l
  • show docstring alt+d
  • find usages of function win+alt+d
  • autoformat file win+r (this cleans up a lot of the formatting-related pep8 warnings, good when refactoring and cleaning old code)

Mac (incomplete)

  • Install XCode

- Not command line tools. If you installed those, uninstall them and xcode-select -s the Xcode app

brew install graphicsmagick postgresql libsass openssl redis

brew install python --with-brewed-openssl

  • Install pip

easy_install pip celery

  • Install latest Java JDK to get java command
  • Do steps NPM, Haxelib, Docker files from the main guide
  • Continue to "Internal Setup"

- pip should be done not with sudo, but with --user flag instead, if problems occur

haxelib 3,2,81 version needs to have a symlink like "latest" as cordova plugin xml parser has a bug which dies on commas in path name. Also, XCode project needs "Build settings" -> "Other linker flags" -> '-stdlib=libc++' for compile to work.

You may also occasionally need to do

export IPHONE_VER=10.0

Windows 10 (WSL)

First, follow this guide to set up WSL. Restart.

Then follow with the standard linux installation (but make sure to put it somewhere in /mnt/)

Docker needs to be set up both inside WSL and in windows proper. Standard docker install requires pro version for Hyper V support. To get around this, install "Docker toolbox" instead Then do

 docker-machine env

in PowerShell, and copy those lines over to the end of your .bashrc (changing path to /mnt/c/User/.... from C:\User\...)

While there, also add the line (required for pip binaries):

 export PATH=$PATH:~/.local/bin

Now we also need to add "DOCKER_HOST":"" to current_project.json to tell our project to look there instead

If Bower gives you trouble,

 chown [username] -r ~/.config

If node-sass is acting up, do

 npm rebuild node-sass

Hosts file is at C:\Windows\System32\Drivers\etc\hosts . To edit it, right-click notepad and choose "Run as Administrator"

Android Dev

HaXe needs to be at least 3.3.0. You also need Android studio (which in turn requires JDK 1.8). Once that is installed, navigate to "Configuration" -> "SDK manager" -> "SDK Tools" and install:

NDK SDK ver 22 SDK build tools ver 22 SDK and Build Tools of <newest>

You will need to set up haxelib. In haxe root folder do:

 haxelib dev MMSNativeExtension MMSNativeExtension
 haxelib dev mms_native tmp/mms_native


 lime setup android

And say n to everything until it starts asking for paths. Then provide them: Android SDK is ~/Android/Sdk NDK is ~/Android/Sdk/ndk-bundle ANT is ~/Android/Sdk/tools Java SDK is /usr/lib/jvm/java-8-openjdk-amd64 (in ubuntu)

You may need to symlink 4.9 to 4.9.x at ~/Android/Sdk/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/{x86,x86_64}/lib/gcc/arm-linux-androideabi

Also, add this to your .bashrc

 export ANDROID_HOME=/home/velochy/Android/Sdk
 export PATH=$PATH:/home/velochy/Android/Sdk/tools
