I installed twill by using pip, and another try using easy_install, I want to play around with it in Powershell. Following this page - http://twill.idyll.org/ I wanted to play around with it.
To start using twill, install it and then type twill-sh. At the prompt type:
go http://www.slashdot.org/
show
showforms
showhistory
When I type twill-sh it doesn't work. I have typed it in power shell, tried it after loading python, and tried it after using import twill and trying it. I only get errors.
Traceback (most recent call last):

How do I just load modules so I can play with them without writing scripts?
I had the same problem. Further down the log I found the following:
File "C:\Anaconda\lib\site-packages\lxml\cssselect.py", line 18, in <module> raise ImportError('cssselect seems not to be installed. '
ImportError: cssselect seems not to be installed. See http://packages.python.org/cssselect/
Which I fixed by installing package cssselect (using conda as I have an Anaconda installation, pip should do the same).
conda install cssselect

But when I use pip install the library is installed, but it still doesn't work in PyCharm.
Thanks for help! And sorry for my english.
you can try to download corresponding pacages in '.tar.gz' format on this link
manually unzip it
enter the unzipped folder
install the package through the following cmd command:
python setup.py install
here I suppose you are using windows and your python is above 3
If you are continuously encontering this problem,I suggest you alter the original download channel to a mirror.
If you installed the library through terminal and Pycharm still doesn't recognize the library, I think may be you should select the correct interpreter for the project by clicking the project interpreter at the bottom right in a Pycharm project. Look at the image in this
link. Click on the Interpreter which is named just "Python 3.x", it may work then.
["3.x" as in which version of python you are using]
I'm using terminal on mac, and anytime I attempt to use pip, I get the following error message telling me that it cannot find a module named zlib:

I've read several SO posts with the same error message, and have tried their solutions, including attempting to install zlib using homebrew, which fails, and updating my Xcode developer tools. I also installed pip earlier using python get-pip.py, and it said it installed successfully.
The reason I need pip is to install a package for use on python 2.7, but doing $ pip install "package-name" produces the same error as above. I have both Python 2 and 3 installed on my machine, if that helps. I'm kind of new to pip and using the command line in general, and I'm super confused; if anyone could help me out I'd really appreciate it.
This is the OP. I was able to fix the issue, and wanted to post my solution here in case it would help others.
Essentially I believe it occurred because Python2 is default on my machine, but pip is by default pointing to resources pertaining to Python3, or something like that. Doing pip2 --version instead provided the expected response.
I needed to install hashlib for one of my projects, and used easy_install hashlib (as was stated by this Stack Exchange post) to do so. However, right after I installed this package, I haven't been able to use pip at all. Whenever I type a command with pip (like pip install), I get the following error message:

This also now occurs when I'm using easy_install- same error. I'm also not able to uninstall pip and reinstall- any command with pip results in the error above. Even executing
pip --version yields the same error. I know it's something to do with the hashlib package, but I'm not sure how to delete it and reinstall without messing up my entire Python configurations. My hypothesis is that the version of hashlib I installed is either too old or too new for my Python 2.7, and doesn't play well with it.
Does anyone know what exactly is going on behind the scenes here in this stack trace, and how I can fix pip?
Is the best thing to do to literally go in and delete hashlib.py from my lib/python2.7 folder?
So, this doesn't solve the issue with hashlib, but it does get you a working pip again: literally download and reinstall Python 2.7 all over again from the source. If anyone comes up with a better, more elegant solution for fixing pip, I am all for it.
However, at least I can use pip again...
I did conda install -c acellera pyinstaller=3.2.3 as per Anaconda's website and it looks like it installed correctly but I get the following if I try to run it via cmd:

What's going on? Pyinstaller works fine with python 2.7 without Anaconda. But I've recently decided to make the jump to Anaconda + 3.5. I cant find any module named pefile or how to install it with Anaconda. I can install pefile easily using pip3 though.
You can use Anaconda's pip to install it, just go to the Script folder in Anaconda and execute:
pip.exe install pefile
install this instead:
conda install -c conda-forge pyinstaller=3.2.1
working fine for me after a couple of tries!
I want to use pyOpenSSL, which I have downloaded and tried to build, but I am having problems with setuptools.

I have installed Python 2.7.6 with PyCharm with no success, and also tried WinPython with the same result.
I am running windows 7 x64.
Since you are facing problem in installing setuptools itself, you can download the windows binary file for setuptools from this link.
This website is a great repository of pre-compiled windows binaries for various Python modules.
If installing 64-bit Python is not a necessity, I would suggest you to install 32-bit version of Python and other modules.
This is related to a bug in Python 2.7.6, to do with Windows Registry corruption.
Some programs (wrongly) write a terminating null to registry entries and this screws up setuptools. Updating Python fixes the issue.
