Installing Python

Semantra is a command-line tool that is built with Python.

To install Semantra, you must first have Python installed, which you can accomplish in several ways:

  • downloading from the Python website
  • via a package manager. For instance, if you have Homebrew installed: brew install python

Open the terminal and verify Python is working via:

python --version

It is recommended to use Python 3.9 or greater.

If you need help installing Python, consult the sections on installing Python 3 from this guide.

Installing Semantra

Once you have Python installed, you are ready to install Semantra. The most convenient way is via pipx. Run the following commands in the terminal:

python3 -m pip install --user pipx
python3 -m pipx ensurepath

Once pipx is installed, you may need to open a new terminal window for the changes to go into affect. Once you launch a new terminal window, Semantra can be installed globally via:

pipx install semantra

If you already have a working installation of Semantra and want to upgrade, you can run pipx upgrade semantra.

Once this command runs, verify that Semantra is installed by running the following in the terminal (it may take several seconds the first time it's run):

semantra

If all goes well, you'll get a print out to the terminal that looks like this:

Usage: semantra [OPTIONS] [FILENAME]...
Try 'semantra --help' for help.

Error: Must provide a filename to process/query

It's time to use the tool!
