I'm having a hard time setting up python packages. EasyInstall from SetupTools is supposed to help that, but they don't have an executable for Python 2.6.
For instance to install Mechanize, I'm just supposed to put the Mechanize folder in C:\Python24\Lib\site-packages according to INSTALL.txt, but runnning the tests does not work. Can someone help shed some light on this? Thanks!
The accepted answer is outdated. So first, pip is preferred over easy_install, (Why use pip over easy_install?). Then follow these steps to install pip on Windows, it's quite easy.
Install setuptools:
curl https://bootstrap.pypa.io/ez_setup.py | python
Install pip:
curl https://bootstrap.pypa.io/get-pip.py | python
Optionally, you can add the path to your environment so that you can use pip anywhere. It's somewhere like C:\Python33\Scripts.
Newer versions of Python for Windows come with the pip package manager. (source)
pip is already installed if you're using Python 2 >=2.7.9 or Python 3 >=3.4
Use that to install packages:
cd C:\Python\Scripts\
pip.exe install <package-name>
So in your case it'd be:
pip.exe install mechanize
This is a good tutorial on how to get easy_install on windows. The short answer: add C:\Python26\Scripts (or whatever python you have installed) to your PATH.
You don't need the executable for setuptools.
You can download the source code, unpack it, traverse to the downloaded directory and run python setup.py install in the command prompt
Starting with Python 2.7, pip is included by default. Simply download your desired package via
python -m pip install [package-name]
As I wrote elsewhere
Packaging in Python is dire. The root cause is that the language ships without a package manager.
Fortunately, there is one package manager for Python, called Pip. Pip is inspired by Ruby's Gem, but lacks some features. Ironically, Pip itself is complicated to install. Installation on the popular 64-bit Windows demands building and installing two packages from source. This is a big ask for anyone new to programming.
So the right thing to do is to install pip. However if you can't be bothered, Christoph Gohlke provides binaries for popular Python packages for all Windows platforms http://www.lfd.uci.edu/~gohlke/pythonlibs/
In fact, building some Python packages requires a C compiler (eg. mingw32) and library headers for the dependencies. This can be a nightmare on Windows, so remember the name Christoph Gohlke.
I had problems in installing packages on Windows. Found the solution. It works in Windows7+. Mainly anything with Windows Powershell should be able to make it work. This can help you get started with it.
Firstly, you'll need to add python installation to your PATH variable. This should help.
You need to download the package in zip format that you are trying to install and unzip it. If it is some odd zip format use 7Zip and it should be extracted.
Navigate to the directory extracted with setup.py using Windows Powershell (Use link for it if you have problems)
Run the command python setup.py install
That worked for me when nothing else was making any sense. I use Python 2.7 but the documentation suggests that same would work for Python 3.x also.
Upgrade the pip via command prompt ( Python Directory )
D:\Python 3.7.2>python -m pip install --upgrade pip
Now you can install the required Module
D:\Python 3.7.2>python -m pip install <<yourModuleName>>
pip is the package installer for python, update it first, then download what you need
python -m pip install --upgrade pip
Then:
python -m pip install <package_name>
You can also just download and run ez_setup.py, though the SetupTools documentation no longer suggests this. Worked fine for me as recently as 2 weeks ago.

Or just put the directory to your pip executable in your system path.
As mentioned by Blauhirn after 2.7 pip is preinstalled. If it is not working for you it might need to be added to path.
However if you run Windows 10 you no longer have to open a terminal to install a module. The same goes for opening Python as well.
You can type directly into the search menu pip install mechanize, select command and it will install:
If anything goes wrong however it may close before you can read the error but still it's a useful shortcut.
I know this Error is known and there are a few solutions, but none worked for me.
I work with eclipse neon + jython 2.7 on a Mac. NO virtualenv.
I want to import pycurl, which is correctly installed!
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
The PythonPath in Eclipse is set to site-packages and pycurl and so on. i already tried every combination!
I restarted eclipse every time after changing something at the paths.
I tried different installations:
sudo -H pip install pycurl
easy_install pycurl
pip -v install pycurl
pip -v install pycurl --upgrade
But if it is installed with one of these methods. it will always say that its already installed, when trying to install via another command.
So I deinstalled and installed multiple times. I even tried it with the download of the pycurl website
So any suggestions, how to make this work?
I don't have much to do with pyCurl, but I try a guess.
Is pyCurl implemented as a ".so"?
If yes: It won't work, because Jython can't deal with it, because it's C-Stuff. Jython can only use pure Python or Java modules.
In that case you have to look for an alternative in Java/Python or you need to find/create a wrapper and use JNI.
If no: Did you add pyCurl in your project source folder the right way?
Did you "import" in your code the right way?
I am new to Python and there are some things which I am not able to apprehend. Questions may seem like very kiddish, so bear with me.
As you know, Ubuntu comes with an outdated Python version. I wished to use the latest python. But since it is recommended not to override the system's python, I installed virtualenv.
I installed pip first, using sudo apt-get install python-pip.
Then installed virtualenv, using sudo pip install virtualenv, and did all the configurations required to link it to the latest python.
The questions which I want to ask are-
Where does the command pip install <module> store the module in the system? I am asking this question because there is a section in this link, which says "Installation into Python". I was confused by this, thinking whether installing a python module is sensitive to which python version I am using. If it is so, then where does pip install the module if I am using virtualenv and otherwise.
I have manually installed Apache HTTP Server 2.4.23 using this link. While installing mod_wsgi using command sudo pip install mod_wsgi, I am getting this error
RuntimeError: The 'apxs' command appears not to be installed or is not
executable. Please check the list of prerequisites in the
documentation for this package and install any missing Apache httpd
server packages.
I searched for it and the solution is to install developer package of Apache. But the problem is that I am not able to find it anywhere on it's site. I want to install it manually. What to do? Also, If I install it through sudo apt-get install apache2-dev, Will there be any difference ?
Note: As mentioned on this link, I have already set the value of APXS environment variable to the location of apxs script, which is /usr/local/apache/bin/apxs.
Concerning 1., if I have well understood, you would like to have the last 2.7 or 3.5 Python version on your distribution. Actually, you can have multiple python distribution on your distribution. I would suggest you to have a look on conda/anaconda (https://www.continuum.io/downloads) : it is very powerful and i think it would better suit you than virtualenv: virtualenv would enable you to create a separate python environnement, but it would not install a newer version of Python.
Concerning 2, I am not an expert in Apache2, but I would have used apt-get instead of re-compiling apache. While compiling, you may need some dependancies to build the mod_wsgi module. So I think it is way more easy to use the pre-built packages from your ubuntu.
Need help updating a python package.
I have an implementation that requires the following import
from twisted.internet.ssl import optionsForClientTLS
"optionsForClientTLS" was added to the twisted framework with version 14(?). I think the non-virtualenv import is getting a dated version-- If that import is within a virtualenv that has twisted installed via pip, everything is fine. Import fails outside the virtualenv.
In the virtualenv
twistd --version
Shows 15.2.1. On the bare system it shows 13.2.0.
pip install twisted
....
pip freeze
shows
Twisted==15.2.1
Uninstalling twisted using pip and reinstalling didn't help. You can install twisted from apt-get using
sudo apt-get install python-twisted
and it installs the older version, but after purging it and installing using only pip I still get the older version.
Possibly related.
I solved the issue in a terrible way. It was a few days ago, so the paths may not be exactly right.
The assumption that there were two python packages was correct (I think.) I suspect the order of the paths in PYTHONPATH meant that the wrong version was being imported first, while pip was installing in a version that was later on in the path.
My "solution" was to copy the twisted directory from the up to date version to the older version. This was either from usr/local/lib/python... to usr/lib/python... or from ... site-packages to ... dist-packages. I can check again if someone has the same issue and can't resolve it.
I am new to Python, trying to learn it by doing a tutorial based on "Dive into Python" book.
I am already in chapter about SOAP and I encountered some problems, when I tried to install all required libraries to use SOAP.
The tutorial says I need 3 libraries:
PyXML, fpconst, SOAPpy
I've installed fpconst succesfully.
However I can't install two others. I read on some forum that to install SOAPpy I need to have PyXML already installed, so maybe the problem is only in the first library.
I followed instructions in README, but I'm getting some error and I don't really know what is wrong and how can solve it. See screen for details. My version of Python is 2.7.2+ and I am trying to install PyXML version 0.8.4.
Full size
The errors states that such file or directory does not exist.
I am using Ubuntu 11.10.
PS: Ah! I forgot to mention that. I downloaded PyXML from this source :
http://sourceforge.net/projects/pyxml/
And it it written here that it is out of date and one shouldn't use it. So what is an alternative to PyXML?
If you are using Ubuntu, why not just install these with your package manager?
sudo apt-get install python-lxml python-fpconst python-soappy
The package manager should be your preferred way to install any software in a Linux distro - it will make your life a lot easier, and ensure you keep things up-to-date and can easily uninstall them.
Failing that, you could also use PyPi - the Python Package Index.
pip install lxml
pip install fpconst
pip install soappy
