Getting started
===============
Electrum is a pure python application. If you want to use the
Qt interface, install the Qt dependencies::
sudo apt-get install python3-pyqt5
If you downloaded the official package (tar.gz), you can run
Electrum from its root directory without installing it on your
system; all the python dependencies are included in the 'packages'
directory. To run Electrum from its root directory, just do::
./run_electrum
You can also install Electrum on your system, by running this command::
sudo apt-get install python3-setuptools
python3 -m pip install .[fast]
This will download and install the Python dependencies used by
Electrum instead of using the 'packages' directory.
The 'fast' extra contains some optional dependencies that we think
are often useful but they are not strictly needed.
If you cloned the git repository, you need to compile extra files
before you can run Electrum. Read the next section, "Development
Version".
Development version
===================
Check out the code from GitHub::
git clone git://github.com/spesmilo/electrum.git
cd electrum
git submodule update --init
Run install (this should install dependencies)::
python3 -m pip install .[fast]
Compile the protobuf description file::
sudo apt-get install protobuf-compiler
protoc --proto_path=electrum --python_out=electrum electrum/paymentrequest.proto
Create translations (optional)::
sudo apt-get install python-requests gettext
./contrib/pull_locale
