Reproduce the issue with the listed pipreqs command, then inspect pipreqs.py around get_all_imports and the AST parsing call. Use libcudacxx/libcxx/utils/generate_feature_test_macro_components.py, especially line 36, as the failing input. Done means pipreqs handles this file without raising the reported SyntaxError.
