第 8 章 Modifying interpreter directives in Python scripts

In Red Hat Enterprise Linux 10, executable Python scripts are expected to use interpreter directives, also known as hashbangs or shebangs, that explicitly specify at a minimum the major Python version. For example: 

#!/usr/bin/python3
#!/usr/bin/python3.12

The /usr/lib/rpm/redhat/brp-mangle-shebangs buildroot policy (BRP) script is run automatically when building any RPM package, and attempts to correct interpreter directives in all executable files. The BRP script generates errors when encountering a Python script with an ambiguous interpreter directive, for example, #!/usr/bin/python or #!/usr/bin/env python.

You can modify interpreter directives in the Python scripts to prevent build errors at RPM build time.

Prerequisites

  • Some of the interpreter directives in your Python scripts cause a build error.

Procedure

  • Depending on your scenario, modify interpreter directives by performing one of the following steps:

    • Use the following macro in the %prep section of your spec file: 

      %py3_shebang_fix <SCRIPTNAME> …​

      SCRIPTNAME can be any file, directory, or a list of files and directories.

      As a result, all listed files and all .py files in listed directories have their interpreter directives modified to point to %{python3}. Existing flags from the original interpreter directive will be preserved and additional flags defined in the %{py3_shebang_flags} macro will be added. You can redefine the %{py3_shebang_flags} macro in your spec file to change the flags that will be added.

    • Modify the packaged Python scripts so that they conform to the expected format.
