Issue with installing sslstrip #27

Comments

anonymous187 commented May 5, 2020

Hi,
I am facing some issues while installing the sslstrip
I run the following command:
python setup.py build && python setup.py install
then when i run:
sslstrip -h
Traceback (most recent call last):
File «/usr/local/bin/sslstrip», line 27, in
from twisted.web import http
ImportError: No module named twisted.web

I have tried installing twisted module using apt-get but unfortunately it is not there anymore
apt-get install python-twisted
Reading package lists. Done
Building dependency tree
Reading state information. Done
Package python-twisted is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘python-twisted’ has no installation candidate

when i install it using pip3 is shows that it is there
pip3 install twisted
Requirement already satisfied: twisted in /usr/lib/python3/dist-packages (18.9.0)

so please can you guide me for the proper way to install it

ImportError: No module named twisted.internet

I installed python 2.7.5 which is working fine.

I then install scrapy (which, I think, uses twisted internally). My scrapy spider is also working fine.

I installed twisted:

sudo apt-get install python-twisted

Then, I created a sample program using Echo Server code shown here

Here is the code

I try to run this code using this command:

Can anyone help me with how I can debug why my twisted package is not being picked up by Python installation?

If you use pip just try:

The same works with w3lib and lxml.

On some *nix systems this might give you a permission error. If that happens, try:

I figured out why this error was happening. For some reason, using apt-get to install a python package was not installing it right.

So, I had to download a tar ball and install the package from them.

I downloaded Twisted tar from here.

I did a tar xjf Twisted-13.1.0.tar.bz2 — this created a directory called Twisted-13.1.0

next, cd Twisted-13.1.0 Finally, python setup.py install

This gave me an error. Twisted required another package called zope.interface. So, I downloaded tar ball for zope.interface from here. Then, ran this command tar xzf zope.interface-3.6.1.tar.gz That created a folder called zope.interface-3.6.1. So, cd into zope.interface-3.6.1 and run python setup.py install

Note: Depending on your user’s rights, you may want to do these commands in sudo mode. Just add the keyword sudo before every command.

ImportError: No module named twisted

I’m pretty new to python and twisted and I tried to run a simple twisted script but failed.

MacOX 10.7.2 + Python 2.7.1 + Twisted 11.0.0 + eclipse + PyDev

The script called test.py:

I tried to run it in the terminal and everything works fine.

Then I opened eclipse and created a new PyDev project then adding a py file called test.py and typed the code above in.

When I tried to run it I got errors like:

Then I checked the PYTHONPATH and added the «twisted source folder» in the external libraries tab but the errors was still there.(nothing changed)

Hope someone can help me out here, thanks in advance 🙂

Several things to try here —

Since your env is Mac OSX. I installed commandline tools from Xcode which solved this problem. Xcode 4.4 and later install Command Line Tools

For the sake of completeness. If this on Ubuntu, then apt-get install python-twisted generally works.

from your eclipse put this in your python script —

python -c ‘import sys;print sys.path’

This tells all the paths that python looks for when you import something . If you don’t find twisted path there then add it to this like so — sys.path.append(twisted_dir_path)

Finally, if all the above does not help. type -p python in a shell will tell you which version you’re using; I would mostly be /usr/bin/ or some variant of it.

Then /usr/bin/python2.7 -c ‘from twisted.internet.protocol import Factory,Protocol’ ought to succeed.

This has happened to me so many times, but I figured out previously. Basically, if you have too many versions of python on your mac, Aptana Studio for some reason gets confused, so make sure that your twisted installation is using the same python as the command line (even though you already added twisted to Aptana). I’ll get into more specifics later

Ok, I think this is how you do it:

1. Grab the python path of the python that has twisted installed correctly, using this
   import sys
   print sys.path
   And just grab the base path, nothing to specific.
2. Go to Aptana-preferences-PyDev-Interpreter-Python
3. And then just add a new interpreter (in my case I just called it python1 and set is the first one. If that doesn’t work then just set a new PYTHONPATH right below it.

You need to install incremental before twisted

This should solve the problem.

Not sure how you installed twisted, did you try easy_install or pip, or install in manually?

If you want to make sure it’s installed properly, try opening up a terminal, typing python, and then «import twisted». If it comes back without errors, then it’s installed. You might need to set the PYTHONPATH variable to include the source folder.

Then, since you’re using pydev in eclipse, you need to refresh your configuration each time you add a new library.

On the mac, this is under preferences -> PyDev -> Interperter-Python

I find it works best to remove my configuration and re-add it, for it to pick up everything. But you can click on new folder (select the folder with the init.py), or the new egg, if it’s an easy_install egg (a .egg file is a zip file, if it’s unzipped, you’ll see a EGG-INFO folder in the subdirectory of the folder you want to select).

Thank you, I thought I was alone! I spent almost my entire morning trying to get this thing up and running on my Mac. I think I got past this somehow, don’t remember how anymore cause I’ve tried a million things.

dyerrington commented Apr 6, 2014

I was able to get past this with

I’ve run into a whole lot of other problems on OSX attempting to set this up. The next thing on the list is:

After this, I ran into another problem with the compiler conflicting in my virtualenv setup. I was able to fix this using this command:

Euphorbium commented Apr 6, 2014

jsonschema is installed in my setup, it would have been too easy, if it was not installed. I am not working on a Mac.

dyerrington commented Apr 6, 2014

@Euphorbium, the message traces back to

To me, it seems that the features in jsonschema the authors programmed against don’t match the features in your currently installed instance of jsonschema. The first time I tried to install portia, I had all sorts of weird things like this popping even with currently installed versions of the prerequisite modules.

After much whiney internal dialog in my head, I decided to setup virtualenv and install everything within virtualenv. Everything went super smooth. Are you using virtualenv? I used these directions:

The hackercodex directions seem fairly agnostic but perhaps if you’re using a flavor of linux there’s an easy apt-get-like package for it? It was actually surprisingly easy to install.

Euphorbium commented Apr 7, 2014

I have found what is wrong here. Somebody wrote requirements.txt by hand and not by pip freeze > requirements.txt, therefore versions of the required libraries are not specified. Somebody that has this thing working, please post the results of pip freeze here, and it should solve this problem for everyone.

This is the first time I’ve ever done anything with git or python, the only thing I’ve programmed is an Arduino and some web scripting basics. So I’m probably not the best to answer the question. But I did get it working by looking for clues. The gist of it, I had a brand new ubuntu server vm, and I needed to install jsonschema and numpy, in addition to what was documented here. I might have also had to apt-get some python stuff, too. but tbh i just kept hammering away and didn’t really document anything. sudo was definitely a part of the solution, as well. Things weren’t getting written properly without it. So I’ve got it web accessible, but I’m stuck at trying to automate a scrape. Does anybody know if there are more resources than the youtube vid?
