I have both Python 2.7 and 3.4 installed on my Ubuntu 14.04 machine. I want to install the 'requests' module so it is accessible from Py3.4.

When I issued pip install requests on my terminal cmd line I got back:

"Requirement already satisfied (use --upgrade to upgrade): requests in /usr/lib/python2.7/dist-packages"

How can I direct pip to install requests for 3.4 even though it is already in 2.7?

You can specify a Python version for pip to use:

pip3.4 install requests

Python 3.4 has pip support built-in, so you can also use:

python3.4 -m pip install

If you're running Ubuntu (or probably Debian as well), you'll need to install the system pip3 separately:

sudo apt-get install python3-pip

This will install the pip3 executable, so you can use it, as well as the earlier mentioned python3.4 -m pip:

pip3 install requests

On Windows with Python v3.6.5

Just answering this old thread can be installed without pip On windows or Linux:

1) Download Requests from https://github.com/kennethreitz/requests click on clone or download button

2) Unzip the files in your python directory .Exp your python is installed in C:Python\Python.exe then unzip there

3) Depending on the Os run the following command:

  • Windows use command cd to your python directory location then setup.py install
  • Linux command: python setup.py install

Thats it :)

while installing python packages in a global environment is doable, it is a best practice to isolate the environment between projects (creating virtual environments). Otherwise, confusion between Python versions will arise, just like your problem.

The simplest method is to use venv library in the project directory:

python3 -m venv venv

Where the first venv is to call the venv package, and the second venv defines the virtual environment directory name. Then activate the virtual environment:

source venv/bin/activate

Once the virtual environment has been activated, your pip install ... commands would not be interfered with any other Python version or pip version anymore. For installing requests:

pip install requests

Another benefit of the virtual environment is to have a concise list of libraries needed for that specific project.

*note: commands only work on Linux and Mac OS

i was facing same issue in beautiful soup , I solved this issue by this command , your issue will also get rectified . You are unable to install requests in python 3.4 because your python libraries are not updated . use this command apt-get install python3-requests Just run it will ask you to add 222 MB space in your hard disk , just press Y and wait for completing process, after ending up whole process . check your problem will be resolved.

i just reinstalled the pip and it works, but I still wanna know why it happened...

i used the apt-get remove --purge python-pip after I just apt-get install pyhton-pip and it works, but don't ask me why...
