How to Include Wkhtmltopdf With Pyinstaller?

3 minutes read

To include wkhtmltopdf with PyInstaller, you first need to make sure that wkhtmltopdf is installed on your system. Once installed, you can include it in your PyInstaller script by using the --add-binary option. This option allows you to add additional files or directories to be included in the bundled executable.


You will need to specify the path to the wkhtmltopdf executable and where it should be placed in the final bundled executable. For example, if the wkhtmltopdf executable is located in /path/to/wkhtmltopdf and you want it to be placed in the root directory of the final executable, you can include it in your PyInstaller script like this:

1
pyinstaller --add-binary /path/to/wkhtmltopdf:./ myscript.py


This will ensure that wkhtmltopdf is included in the bundled executable when you run PyInstaller on your script. Make sure to adjust the paths and file names as needed for your specific setup.


What are the limitations of using wkhtmltopdf with PyInstaller?

  1. Incompatibility with some operating systems: PyInstaller may encounter issues when trying to bundle wkhtmltopdf with applications that are intended to be run on certain operating systems, such as macOS.
  2. Large file size: Including wkhtmltopdf with PyInstaller can substantially increase the size of the final executable, which may not be ideal for all applications.
  3. Dependency management: PyInstaller may not handle dependencies of wkhtmltopdf properly, leading to errors or issues when running the application on different machines.
  4. Limited support and updates: PyInstaller may not always be up-to-date with the latest versions of wkhtmltopdf, which could result in compatibility issues or bugs.
  5. Performance concerns: Generating PDF files using wkhtmltopdf within a PyInstaller application may impact the performance of the application, especially when processing large amounts of data or complex HTML content.


What is the best way to bundle wkhtmltopdf with PyInstaller?

The best way to bundle wkhtmltopdf with PyInstaller is to include the wkhtmltopdf binary as a data file in your PyInstaller spec file.

block_cipher = None

a = Analysis(['your_script.py'],
             pathex=['/path/to/script'],
             binaries=[('/path/to/wkhtmltopdf_binary', 'wkhtmltopdf_binary')],
             datas=[],
             hiddenimports=[],
             hooks=[],
             runtime_hooks=[],
             excludes=[],
             cipher=block_cipher)

pyz = PYZ(a.pure, a.zipped_data,
            cipher=block_cipher)

exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='your_script',
          debug=False,
          strip=False,
          upx=True,
          runtime_tmpdir=None,
          console=False )


  1. Copy the wkhtmltopdf binary to the specified path in the spec file.
  2. Run PyInstaller with the spec file:
1
pyinstaller your_spec_file.spec


  1. Your final packaged executable should include the wkhtmltopdf binary and be able to run smoothly.


What are the common issues when including wkhtmltopdf with PyInstaller?

Some common issues when including wkhtmltopdf with PyInstaller include:
