I am trying to generate a parser using antlr4ng. I’ve already installed antlr4ng and antlr4ng-cli using npm install antlr4ng and npm install antlr4ng-cli. But when trying to execute antlr4ng -Dlanguage=TypeScript -o generated/ -visitor -listener -Xexact-output-dir path/to/YourLexer.g4 path/to/YourParser.g4 it says command not found: antlr4ng. I hope you have a solution for me.
