How to install requests module in Python 3.4, inst

问题:

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?

回答1:

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, as well as the earlier mentioned python3.4 -m pip:

pip3 install requests

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 :)

On Windows with Python v3.6.5

py -m pip install requests

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...
