Scapy installation fails due to invalid token

python terminal installation scapy

Update: scapy-python3 is deprecated (2018) and will no longer be updated. scapy>=2.4.0 has merged python 3 compatibility.

The most up-to-date installation method is now

pip3 install scapy>=2.4.0

You may check the installation page in the documentation for other installation methods

Original answer:

Perhaps you are trying to install the package scapy for Python 2, but you need the one for Python 3.

pip install scapy

gave this error:

os.chmod(fname,0755)                  ^SyntaxError: invalid token

while

pip3 install scapy-python3

did a proper install.

This error means the octal number is not recognized by Python 3, see PEP 3127:

octal literals must now be specified with a leading "0o" or "0O" instead of "0";

python terminal installation scapy

The following works for me on Python 3.5

pip3.5 install scapy-python3

python terminal installation scapy

Change os.chmod(fname,0755) to os.chmod(fname,0o755) and re-run
