Question
Answer and Explanation
The error "undefined symbol: sqlite3_deserialize" in `sqlite3.cpython-312-x86_64-linux-gnu.so` typically arises when the Python SQLite3 module is trying to use a function (`sqlite3_deserialize`) that is not available in the underlying SQLite library it's linked against. This usually indicates a version mismatch or an issue with how the SQLite library was compiled or installed.
Here's a breakdown of the common causes and how to address them:
1. SQLite Library Version Mismatch:
- The `sqlite3_deserialize` function was introduced in SQLite version 3.35.0. If the `sqlite3.cpython-312-x86_64-linux-gnu.so` module is compiled against an older version of the SQLite library, this function will be missing, leading to the "undefined symbol" error.
- Solution: Ensure that the SQLite library installed on your system is version 3.35.0 or later. You might need to upgrade your system's SQLite package or compile SQLite from source and then recompile the Python SQLite3 module.
2. Incorrect Compilation of the Python SQLite3 Module:
- If the Python SQLite3 module was compiled against a different SQLite library than the one available at runtime, this can also cause the issue. This can happen if you have multiple versions of SQLite installed or if the module was compiled in a different environment.
- Solution: Reinstall the Python SQLite3 module, ensuring it's linked against the correct SQLite library. You can often do this by using `pip install --force-reinstall pysqlite3` or `pip install --no-binary :all: pysqlite3` to force a recompile.
3. System Library Path Issues:
- The system might be looking for the SQLite library in the wrong location. This can happen if the library path is not correctly configured.
- Solution: Verify that the system's library path includes the directory where the correct SQLite library is located. You might need to adjust environment variables like `LD_LIBRARY_PATH` or `LIBRARY_PATH`.
4. Virtual Environment Issues:
- If you are using a virtual environment, ensure that the environment is using the correct SQLite library. Sometimes, the virtual environment might be using a system-wide SQLite library that is not compatible.
- Solution: Activate your virtual environment and reinstall the Python SQLite3 module within the environment.
5. Corrupted Installation:
- A corrupted installation of the Python SQLite3 module or the SQLite library can also cause this issue.
- Solution: Try reinstalling both the Python SQLite3 module and the SQLite library.
Troubleshooting Steps:
- Check SQLite Version: Use `sqlite3 --version` in your terminal to check the version of SQLite installed on your system.
- Reinstall pysqlite3: Use `pip uninstall pysqlite3` followed by `pip install pysqlite3` to reinstall the Python SQLite3 module.
- Force Recompile: Use `pip install --no-binary :all: pysqlite3` to force a recompile of the module.
- Check Library Paths: Verify that the system's library paths are correctly configured.
By systematically checking these potential causes, you should be able to resolve the "undefined symbol: sqlite3_deserialize" error. Remember to always ensure that your SQLite library and Python SQLite3 module are compatible and correctly installed.
