Pip Install Error

[egecemkirci]

I tried pip install scapy-ssl_tls for quick installation. However, I receive an error and I cannot come up with a fix.

cwd: /tmp/pip-install-r0kr9z_r/scapy-ssl-tls/ Complete output (6 lines): Traceback (most recent call last): File "<string>", line 1, in <module> File "/tmp/pip-install-r0kr9z_r/scapy-ssl-tls/setup.py", line 31 except AttributeError, ex: ^ SyntaxError: invalid syntax ---------------------------------------- ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

I cannot understand the problem because it is supposedly from an invalid syntax. Do you have any ideas?

Easy Solution, use the second installation method, first download the code, then correct the code by deleting ", ex" and the next print line. It will build successfully.

modify File "setup.py" in line 32
except AttributeError, ex -> except AttributeError as ex
this should solve it.

I know that you update setup.py....
But there is still a possible mistake for most users like me
SCAPY has best compatibility with Python2.7
and if you try to install this package or other scapy related repo with python3 then maybe simply faced on various errors...

Then best way to install and use scapy-ssl-tls is:

1. python2.7 -m pip install -U cryptography
2. pip2.7 install --pre scapy[basic]
3. pip2.7 install scapy-ssl_tls

I report the issue as still present when installing with Python 3.10.12 and pip 22.0.2:

Collected: scapy-ssl_tls-2.0.0.tar.gz

        File "<string>", line 2, in <module>
        File "<pip-setuptools-caller>", line 34, in <module>
        File "/tmp/pip-install-mmji30wr/scapy-ssl-tls_87acac1301f14212a1dbed2d444318f6/setup.py", line 31
          except AttributeError, ex:
                 ^^^^^^^^^^^^^^^^^^
      SyntaxError: multiple exception types must be parenthesized

The source installation method works (scapy-2.4.5.tar.gz is collected) but the following deprecation message is displayed during installation:

setup.py install is deprecated. Use build and pip and other standards-based tools

althought installation completes successfully
