Solving the PySide Error: “File for inject code not exist: ../doc/qtqml_functions.rst”

If you’re a PySide enthusiast, chances are you’ve come across the frustrating error “File for inject code not exist: ../doc/qtqml_functions.rst” while trying to build your Qt-based project. Don’t worry, you’re not alone! This error can be a real showstopper, but fear not, dear reader, for we’ve got the solution right here.

What causes the error?

Before we dive into the solution, let’s understand what’s causing this error in the first place. PySide is a Python binding for the Qt application framework, and when you’re building a Qt-based project, PySide needs to inject some code into the Qt documentation files (in this case, qtqml_functions.rst). The error occurs when PySide can’t find the file it needs to inject the code into.

Why does PySide need to inject code?

PySide injects code into Qt documentation files to expose Qt’s functionality to Python. This process is called “doc injection.” When PySide injects code, it generates Python wrappers for Qt’s C++ classes and functions, allowing you to use Qt’s features seamlessly in your Python code. Without doc injection, you wouldn’t be able to use Qt’s functionality from Python.

Solving the error: Step-by-Step Guide

Now that we’ve covered the why and what, let’s get to the how! Follow these steps to solve the “File for inject code not exist: ../doc/qtqml_functions.rst” error:

1. Check your Qt installation

   Make sure you have Qt installed on your system, and the Qt documentation files are present in the correct location. You can download the Qt installer from the official Qt website.

2. Verify your PySide installation

   Ensure you have PySide installed correctly. You can install PySide using pip: pip install PySide2. If you’re using a virtual environment, make sure PySide is installed in the correct environment.

3. Check the qtqml_functions.rst file location

   The qtqml_functions.rst file should be located in the Qt documentation directory. The default location is $QTDIR/doc/qtqml_functions.rst, where $QTDIR is the path to your Qt installation directory.

4. Update your PySide configuration

   In your PySide configuration file (usually setup.py or CMakeLists.txt), update the QT_INSTALL_DOCS path to point to the correct location of the Qt documentation files.

         # setup.py example
         setup(
             ...
             qt_install_docs="path/to/qt/doc",
             ...
         )
       

5. Regenerate the PySide wrappers

   After updating the configuration, regenerate the PySide wrappers using the following command: python setup.py build. This will rebuild the PySide wrappers using the updated configuration.

Troubleshooting Tips

If you’re still encountering issues, try the following troubleshooting tips:

• Check for file system permissions

  Ensure that your Python script has read and write access to the Qt documentation directory.

• Verify the Qt version

  Make sure you’re using a compatible version of Qt with your PySide installation. Check the PySide documentation for compatible Qt versions.

• Disable Qt’s namespace tracing

  Sometimes, Qt’s namespace tracing can interfere with PySide’s doc injection. Try disabling namespace tracing by setting the QT_NAMESPACE_TRACE environment variable to 0.

        export QT_NAMESPACE_TRACE=0
      

Conclusion

You’ve made it! By following these steps and troubleshooting tips, you should be able to solve the “File for inject code not exist: ../doc/qtqml_functions.rst” error and get back to building your Qt-based project.

Remember, PySide is a powerful tool for building Qt-based applications in Python, and with a little patience and persistence, you can overcome this common error and unlock the full potential of PySide.
