Before installing Picard from source, you need to check you have the following dependencies installed.

Required:

• Python 3.6 or newer
• PyQt 5.11 or newer
• Mutagen 1.37 or newer
• PyYAML 5.1 or newer
• python-dateutil
• gettext:
  • Windows
• a compiler
  • Windows should work with Visual Studio Community 2019

Optional but recommended:

• chromaprint
  • Required for fingerprinting (scanning) files
• python-discid or python-libdiscid
  • Required for CD lookups.
  • Depends on libdiscid Note: Due to slowdowns in reading the CD TOC, using libdiscid versions 0.3.0 - 0.4.1 is not recommended.
• python-markdown
  • Required for the complete scripting documentation
• PyJWT 1.7 or newer
  • Required for the add cluster as release / add file as recording functionality

We recommend you use pip to install the Python dependencies:

Run the following command to install PyQt5, Mutagen and discid:

pip3 install -r requirements.txt

The binaries for Python, GetText (msgfmt), fpcalc and discid.dll have to be in the %PATH% on Windows.

The recommended way to install Picard from source is using pip. After installing the dependencies, you can install Picard as a pip package by running:

pip3 install .

To start Picard now you can use:

picard

To uninstall Picard run:

pip3 uninstall picard

You can also install Picard with setup.py by running:

sudo python3 setup.py install

This will automatically build and install all required Python modules. On Windows you need to have Administrator rights, but don't put sudo in front of the command.

To start Picard now you can use:

picard

If you want to be able to easily uninstall Picard again, run setup.py with the --record installed-files.txt command line argument. This will record all files generated during installation into the file installed-files.txt.

sudo python3 setup.py install --record installed-files.txt

To uninstall Picard again simply remove all the files listed in installed-files.txt, e.g. by running:

rm -vI $(cat installed-files.txt)

If you want to run Picard from the source directory without installing, you need to build the C extensions and locales manually:

python3 setup.py build
python3 setup.py build_ext -i
python3 setup.py build_locales -i

And to start Picard use:

python3 tagger.py

To run the included tests, follow the instructions for "Running From the Source Tree". Afterward you can run the tests using setup.py:

python3 setup.py test

Picard supports packaging binaries and uploading them to PyPi.

To submit a package run:

python3 setup.py sdist
twine upload dist/*
