Could not build wheels for cx_Oracle, which is required to install pyproject.toml-based projects

It seems like you encountered an issue while trying to install a package that requires cx_Oracle. The error message "Could not build wheels for cx_Oracle" indicates that there were problems building the necessary binary wheels for cx_Oracle.

To resolve this issue, you can try the following steps:

1. Make sure you have the necessary dependencies installed. cx_Oracle requires Oracle Instant Client libraries to be installed on your system. You can download the libraries from the official Oracle website.

2. Ensure that you have the correct version of Oracle Instant Client libraries installed. Different versions of cx_Oracle require specific versions of Oracle Instant Client libraries. Make sure you have the correct match.

3. Set the required environment variables. After installing the Oracle Instant Client libraries, set the `LD_LIBRARY_PATH` (Linux) or `PATH` (Windows) environment variable to point to the directory where the libraries are installed.

4. Try installing cx_Oracle again. You can use pip to install it: `pip install cx_Oracle`. If the error persists, you might need to specify additional installation options, such as specifying the path to the Oracle Instant Client libraries explicitly.

If you continue to experience issues, please provide more details about your setup and the specific error message you are encountering so that I can assist you further.
