Sorry, I'm a novice, and I don't know much about this. I'm preparing to learn related knowledge. The above error occurred when I was preparing to run a tool named PiRL. So what should I do to regenerate the parser? Thank you very much for your patience.

[ericvergnaud]

I know nothing about PiRL, so can't really help. Please read the online docs to find out how to regenerate your parser.

Which file explains how to regenerate my parser?please? I have the same problem when using antlr4, which can not be solved so far. Thank you for your answer.

Hi,

I had the same issue with exactly the same error message when I tried to run the 04-Calc example from py3antlr4book.

The GIT repo of py3antlr4book shipped an old version of ANTLR (antlr-4.7.2-complete.jar), which is incompatible with the latest antlr4-python3-runtime that I installed via PyPI (4.11.1).

In my case, I upgraded the version of ANTLR for generating the parser and created a PR to fix the issue in the book: https://github.com/jszheng/py3antlr4book/pull/15. Using the antlr4 executable that ships with antlr4-python3-runtime instead of the JAR from py3antlr4book also solves the problem.

In your case, you probably either have to regenerate the parser of the PiRL tool using the latest ANTLR or downgrade to an older version of the Python 3 package antlr4-python3-runtime if you don't want to make changes in PiRL.

Try to reinstall antlr4 runtime with appropriate version: pip uninstall antlr4-python3-runtime pip install antlr4-python3-runtime==<ANTLR version> To check your ANTLR version run antlr4 command.

I downgraded my antlr4-python3-runtime to 4.9.3 and the error fixed.

I installed with pip install antlr4-python3-runtime==$(antlr4 | grep Version | awk '{print $5;}')
