akracer is a Python library that serves as an extension for py_mini_racer, specifically designed to address dynamic link library (DLL) calling issues on 64-bit ARM operating systems. It facilitates a one-click installation of py_mini_racer by providing pre-compiled dynamic link libraries for environments like Apple M-series chips, Ubuntu (18.04, 20.04, 22.04), and Raspberry Pi 64-bit OS. The current version is 0.0.14. It is actively maintained with a beta development status.
pip install akracer Common errors
error ModuleNotFoundError: No module named 'akracer' ↓
cause The 'akracer' module is not installed in the Python environment.
fix
Install the 'akracer' module using pip: 'pip install akracer'.
error ImportError: cannot import name 'akracer' ↓
cause The 'akracer' module is not installed or the import statement is incorrect.
fix
Ensure 'akracer' is installed with 'pip install akracer' and use the correct import statement: 'import akracer'.
error AttributeError: module 'akracer' has no attribute 'some_function' ↓
cause Attempting to access a function or attribute that does not exist in the 'akracer' module.
fix
Verify the function or attribute name in the 'akracer' module's documentation and use the correct name.
error TypeError: 'NoneType' object is not callable ↓
cause Calling a function that returns None, possibly due to an incorrect function call in 'akracer'.
fix
Check the function's return value and ensure it is not None before calling it.
error ValueError: Invalid parameter value in 'akracer' function ↓
cause Passing an invalid parameter value to a function in the 'akracer' module.
fix
Review the function's parameter requirements in the 'akracer' documentation and provide valid values.
Warnings
gotcha akracer primarily addresses dynamic library issues for py_mini_racer on 64-bit ARM operating systems. While installing akracer may not hurt on other architectures, its primary benefit is for ARM users. On x86-64, py_mini_racer typically installs and compiles correctly without akracer. ↓
fix Only install akracer if you are on a 64-bit ARM operating system and experiencing issues with py_mini_racer's native installation. Otherwise, `pip install py_mini_racer` might suffice.
breaking The project is currently in '4 - Beta' development status according to PyPI. This indicates that the API or stability might not be fully mature and could be subject to breaking changes in future releases. ↓
fix Monitor release notes and the GitHub repository for updates and potential breaking changes. Consider pinning to specific minor versions to mitigate unexpected issues.
gotcha A security analysis by ReversingLabs indicated that the akracer package contains 'risks' and 'known severe vulnerabilities' that are actively being exploited. Users should review the analysis results before use. ↓
fix Exercise caution and consult the latest security reports for the library. Implement robust security practices in projects using akracer, such as regular dependency scanning and ensuring isolated execution environments.
