Ok, so i've downloaded the following library:
http://www.lag.net/paramiko/
and i can't seem to figure out how to install on my local machine:
Mac OS X 10.4.11
To use the package that you got from the web-site: "python setup.py install
"
My advice is to use easy_install instead of downloading packages straight from the project web-site.
To do this, you must first install setuptools.
Then just use the command "easy_install paramiko".
As you use lots of different packages, this ends up saving you lots of hassle.

Okay, so, I'm running Python 3.4.3 with pip 9.0.1, with the setuptools and wheel.
I'm running this inside JetBrains PyCharm Professional 2017.2.3.
The issue I'm having is trying to install the twitter api packages from this tutorial (ya I'm a n00b) http://wiki.openhatch.org/Twitter
I'm struggling with installing the 4 dependencies mentioned in the first part of the tutorial (httplib2, simplejson, oauth2 and python-twitter)
Honestly, I'm just getting back into programming and this is a project I'd like to complete.
So, I need help with:
Installing pip, and how to use it, and where (python shell or command line or)
the dev.twitter.com website (and where to find what I need from there)
Any help is massively appreciated and sorry if I sound really n00by, but do correct me where I'm using incorrect terms etc because that's how I learn I guess :)
If you haven't got pip installed, find your python installation file.Execute it and choose 'Change Python Installation'. Now choose 'pip' to install and 'add python.exe to path'. Wait for it to finish. Now run windows command line and type:
pip install package_name
Sometimes you may experience that a package isn't available on pip or doesn't work.There are 2 common (not always working) ways to install a package without making pip download the file:
1) A package may be available as a .whl file for download.Download it.Now find it and copy its name .Open a command line in dictionary where it is located and type
pip install **now paste the filename and add .whl**'
2)A package is available as a zip file.Packages are often packed into a zip file.Download the file and extract it.Open a command line in it's directory.You may see setup.py file.Run
python setup.py install
When finished installing pip and adding python to path,you can run:
pip install httplib2 simplejson oauth2 python-twitter
Done.
Once you have pip installed, open the command prompt and just type pip install name_of_the_extension.
In this case, pip install httplib2 will install this package.
I believe you have pip installed on your computer, so it shouldn't be a problem to install the 4 packages you need.
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 have both Python 2.7 and Python 3.4 (and have to have both because for the class I'm running, students have the option of using either). One student has used Python 2.7 and numpy for their project, but when I attempt to install numpy, it installs it to 3.4. I need to install it to 2.7.
I'm using numpy 1.9 from this site, which I'm told is also 2.7-specific: http://sourceforge.net/projects/numpy/files/NumPy/
However, nonetheless it still goes to the 3.4 folder. Copying it to Python 2.7 didn't work, obviously.
How do I do this?
I recommend installing with pip.
pip install numpy
If this doesn't work on windows then download the binary from http://www.lfd.uci.edu/~gohlke/pythonlibs/ and convert it to a wheel before installing.
pip install wheel
wheel convert path/to/binary
pip install numpy_wheel
Pip is recommended because you can uninstall.
To check where you are installing to
pip -V
You may have an environmental variable path to the wrong pip.
Assuming that you are using, or at least you should use pip to install the library. You can specify the python version to be installed by changing the suffix, e.g. pip-2.7 install numpy.
pip install numpy
pip-2.7 install numpy
pip-3.4 install numpy
As an alternative, in case that you do not want to use pip is to download and install the library using setup with a similar technique.
python setup.py install
python2.7 setup.py install
python3.4 setup.py install
Your PATH isn't setup correctly.
C:> where pip
Should tell you which pip it is trying to use, and it is likely whichever one it found on your PATH first...
So, instead, you will want to run it as
C:> C:\mypython2install\pip.exe install numpy
Or, setup your path correctly. See here
Just one other note on issues like this. I had a similar problem with Python 2.7 libraries not being found, because I had miniconda installed for a Python virtual environment that was hijacking calls to python from other programs. After deleting the minconda directory in my home the problem went away and python libraries that were properly installed were found again.
Note-This answer is particularly for Windows PC which has both Python2 & Pyhton3 installed on it.
Both the versions of Python has their different directories somewhat like
"C:\Python27\" ----for python2
"C:\Python35\" ---- for python3
*(or it depends on what path you chose while installing Python**)*
pip GENERALLY exist under the directory "C:\Python**\Scripts"
there you can find exe files like:
pip.exe/pip2.exe/pip2.7.exe ----for python2
pip3.exe/pip3.5.exe ----for python3
to install packages on python2:
use
Python27\Scripts\pip2.exe install package_name
(where the 1st argument is the path of exe file, it might differ for your system)
to install packages on python3:
use
Python35\Scripts\pip3.exe install package_name
there is no need to uninstall any version of python to achieve the task.
I'm trying to install openpyxl and I haven't the clue how to install it. I have my C:\Python27...but what directory do I put it in? FYI, I'm a complete noob to modules and what not...I appreciate your help.
I have put in the lib and libs directory of python and try installing it to no avail. Here is a link to the site I got my download... http://pythonhosted.org/openpyxl/.
Basically, I extracted the file and move it to the lib directory. However, I cannot import it.
There is a setup.py script provided. Typically you run:
python setup.py install
From the directory were you've downloaded the library, and it gets installed automatically.
Consider also more convenient tools that manage installing Python libraries in general like pip or easy_install mentioned in other answers and comments.
It's even easier when the package is on the Python Package Index (PyPI). Just install pip and use it to download and install the package and all its dependencies.
https://pypi.python.org/pypi/pip
I have Python 2.7, and I have distutils installed.
I downloaded the latest version of Scipy for win 32.
For the life of me, I do not understand how to install it.
From the directions on the site, it states:
If you already have Python installed, the easiest way to install Numpy
and Scipy is to download and install the binary distribution from
Download.
I have followed the above directions and downloaded this.
I cannot figure what to do now!
How do I finish getting scipy installed?
It looks like you've downloaded the source distribution, which you would normally install by doing:
python setup.py install
However, without the proper C compiler environment and other libraries, it will probably fail. I'm guessing you really wanted to download the Windows binaries .
You have to drill a little further down in the sourceforge site to find it.
try downloading the windows binary ...
http://sourceforge.net/projects/scipy/files/scipy/0.11.0/scipy-0.11.0-win32-superpack-python2.7.exe/download
You'll be well off installing setuptools. Makes installing almost anything python-related a breeze!
e.g.
easy_install scipy
There's another one called pip.
easy_install pip
pip install scipy
just open windows command prompt and go to the directory you have installed Python. e.g
c:\python34>
Once there, just type python -m pip install scipy and press enter
