 Trivy parses your files generated by package managers in filesystem/repository scanning.
 
 ### pip
+Trivy only parses [version specifiers](https://packaging.python.org/en/latest/specifications/version-specifiers/#id4) with `==` comparison operator and without `.*`.
+To convert unsupported version specifiers - use the `pip  freeze` command.
+
+```bash
+$ cat requirements.txt 
+boto3~=1.24.60
+click>=8.0
+json-fix==0.5.*
+$ pip install -r requirements.txt
+...
+$ pip freeze > requirements.txt 
+$ cat requirements.txt 
+boto3==1.24.96
+botocore==1.27.96
+click==8.1.7
+jmespath==1.0.1
+json-fix==0.5.2
+python-dateutil==2.8.2
+s3transfer==0.6.2
+setuptools==69.0.2
+six==1.16.0
+urllib3==1.26.18
+wheel==0.42.0
+```
+
 `requirements.txt` files usually contain only the direct dependencies and not contain the transitive dependencies.
 Therefore, Trivy scans only for the direct dependencies with `requirements.txt`.
