我正在尝试使Coverity扫描正常工作，但是当我尝试运行Coverity网站上建议的命令时，会发出0个编译单元：
$ cov-build --dir cov-int --no-command --fs-capture-search .

0 Python compilation units (0%) are ready for analysis
The cov-build utility completed successfully.
我尝试删除--no-command并运行python应用程序（cov-build --dir cov-int --no-command --fs-capture-search python main.py），但仍未准备任何编译单元。 build-log.txt中没有错误，唯一的警告是：
[WARNING] During pre_translate, unrecognized option: --fs-capture-search
我也尝试运行cov-configure --comptype python --compiler python2 --template（对于python2和python3都运行，因为我的代码可以在两个版本中运行），但也没有任何变化。知道我在做什么错吗？
