I get an error message when I run the following line of code
import requests
Here is the error message
Traceback (most recent call last):
File "C:\Python27\test", line 1, in <module>
import requests
ImportError: No module named requests
Based on what I've seen from other posts, the common reason for the problem is individuals download the requests module but have not installed it. I downloaded the tarball, unzipped it and installed the setup.py file via the computer command line. There is a requests-2.4.0-py2.7.egg folder in the Python27/Lib/site-packages folder.
For Windows, install pip. You'll probably need other packages later on, so it will pay off to have a proper package manager.
Here is the documentation: https://pip.pypa.io/en/latest/index.html
You might actually be missing certifi module.
Overview:
From your error stack trace, it appears that you are using Windows platform and have the native windows Python installation. So I will stick to Windows instructions here. But since I have Cygwin based python installation, I will provide here cygwin-based steps to resolve your issue.
However, you can very easily use these steps on the Windows command prompt as well, by installing pip or easy_install, pre-built binary, or source code.
Windows-Cygwin-Pip way:
Add the directory that hosts python executable to your environment's PATH variable. Instructions here
Get pip to easily install new python packages. Best way is to download get-pip.py in cygwin’s home directory and run python get-pip.py in cygwin bash shell command prompt. Detailed and Alternative instructions here
Run pip install requests in the cygwin bash shell. It will install requests and certifi packages, which results in results, requests-2.4.0.dist-info, certifi, and certifi-14.05.14-py2.7.egg-info in the /lib/site-packages folder.
Run python and execute your original line of code import requests. It will run without errors.
Alternatives Ways to Installing a New Package:
There are several other alternatives of downloading this requests package, or for that matter any new python package. These include:
Getting easy_install in Cygwin and Running easy_install requests. Get easy_install in cygwin by installing setuptools package or by following instructions here.
Downloading a pre-built binary available here. And running it as executable. It will automatically install the module under the latest python installation available in windows registry.
Downloading source code for requests from Github into the home directory and Running python setup.py install
Python-Requests Installation Doc:
There is a brief list of ways to install requests available on the original python-requests project website as well. See here.
For a more productive environment and saving lots of headaches, follow these steps:
Install virtualenv
Install virtualenvwrapper
Always manage your environments with virtualenvwrapper
Always use pip to install dependencies inside your virtual environment
Use 'pip freeze --local' to see what's installed or to produce a requirements.txt file (pip freeze --local > requirements.txt )
If you have no idea what I'm talking about, you should spend some time reading up on these things, and you'll discover one of the many things that makes python so nice to work with (well, ok other programming languages have similar tools)

I'm in a situation, where I have internet access on a computer but do not have permisson to install anything and python is missing as well.
Python on the other hand is installed on another computer without internet access. Both are in separate networks but i can transfer files through a file server which is connected to each computer as a networkn drive.
My quesion is, if it is possible to download packages with all the dependencies without having python and pip installed, than transfer the file and finally install it.
I simply tried to install a downloaded package from the PyPi Website as a *.zip or *.tar.gz file using the cmd with
chdir \path\to\package\file
python setup.py install
Importing that package afterwards creates errors as the dependencies are missing.
It would be totally fine if I just download Anaconda as all needed packages are already included with the installation. But I would still have the same problem when I want to update the packages.
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 been trying to install paramiko module on windows without success. I have been getting errors related to Visual C++ compiler missing. Is it possible to install paramiko without having to go through compile process.
Based on the method from this question this is what I would suggest (assuming you already have >=python-2.7.9 installed, if not, upgrade, 2.7.9 comes with pip, pre 2.7.9 doesn't):
Get the appropriate pycrypto whl file (based on python version and win32/win_amd64). I've found some available here (can't vouch for the site as I don't use python on windows much).
Run pip install pycrypto-stuff.whl (in a command prompt window in the directory where you've saved the pycrypto whl file).
Run pip install paramiko (in a command prompt, but can be in w/e folder you like).
That should do the trick. In general a simple pip install package_name would work, but pycrypto does not provide a wheel file (binary package), therefore you have to build it. By the sound of it you don't have Visual C++ installed (or not the right version, it only works for one, I don't recall which), pycrypto needs an extension package built to use the system crypto libraries, which is why the source package isn't working.
I was able to get it working by installing the following packages using pip.
pip install bcrypt cryptography pynacl paramiko
These were the packages my Linux install used as prerequisites, so they should work on windows as well.
I get this error when running code, so it appears that requests hasn't installed properly. I am running Windows 7 32-bit system with Python 3.3.
When I go into 'Programs and Features' in windows it shows up as installed.
I installed this program from http://www.lfd.uci.edu/~gohlke/pythonlibs/ and I have also downloaded the requests folder and tried installing it this way, I can't seem to get this to work.
I have visited ImportError: No module named 'requests' already, but I didn't find this helped at all.
I keep seeing the following statement, but I am uncertain of how to run this?
$ python setup.py install
Please help!?!
The answer there is clear. But let me explain to you as good as I can. This error comes because requests module is not installed in your system
Download the requests module to your system from here
And extract it. Go to your command prompt/terminal and reach to the folder you downloaded.There, you will see setup.py, the file that you need to execute to install the requests module.
python setup.py install
Installs the requests module
This line:
$ python setup.py install
It's a command line in a terminal in Linux or the alike. My guess is that you could do the same opening a terminal in Windows pressing the start key and typing 'cmd', without quotes of course. If you had python already install the %PATH% variable should be set up properly and it should just run. Well, perhaps you need to go to the same folder as the setup.py using
> cd path_to_file
And then,
> python setup.py install
I hope it helps. Let me know otherwise.
If you are using Ubuntu, there is need to install requests
run this command:
pip install requests
if you face permission denied error, use sudo before command:
sudo pip install requests
