Installing Python Packages to FME Desktop

If you want workspaces to reference custom Python modules that are part of a Python package, you must:

1. Install a custom Python interpreter.
2. Install the pip package management system.
3. Use pip to install the package to FME Desktop.

Note: The default interpreter included with FME is not available for Python packages because installing pip to that interpreter requires modifications to the FME installation directory, which is not recommended.

Installing a Custom Python Interpreter

1. Install a Python 2.7 interpreter from https://www.python.org/downloads/.
2. Ensure the installation path of the interpreter is added to the PATH environment variable.

Installing pip

1. To get pip, securely download the contents of https://bootstrap.pypa.io/get-pip.py.
2. From a command prompt, navigate to the directory to which get-pip.py was downloaded.
3. Run the command:

> python get-pip.py

Installing Python Packages

To install a package, run the following command:

> python -m pip install <package_name> --target C:\Users\<user>\Documents\FME\Plugins\Python

For example, to install a package named PyExecJS:

> python -m pip install PyExecJS --target C:\Users\<user>\Documents\FME\Plugins\Python

Note: Substitute <user> with the Windows user name.
