Python 3.5.0 can't install anything through pip version 7.1.2

Question

When I try to install anything with (for example) python3 -m pip install numpy , I get

Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy

I've tried upgrading pip3 with python3 -m pip install --upgrade pip but have only gotten

Requirement already up-to-date: pip in 
/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site- 
packages

and when I do python3 -m pip --version I get

pip 7.1.2 from /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (python 3.5)

I'm unable to install any modules at all. Any advice? I am on MacOS.

Answer 1

To solve your problem, I suggest you use brew as the package manager and install python, not as binary from the python.org but binary using brew ( https://brew.sh ), I hope it'll fix your troubles, during the installation process.

1. Install brew package manager:

   $ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install )"

2. Install " python3 " on your machine ( python2 can be installed in the same way ):

   $ brew install python3

3. Check what version of python you are using:

   $ which python3

   Output ( should look like ): /usr/local/bin/python3

4. Check what pip you are using:

   $ which pip3

   Output ( should look like ): /usr/local/bin/pip3

5. Then you can install any package using "pip" :

   $ pip3 install virtualenv

6. Verify that package was installed :

   $ pip3 freeze | grep virtualenv

Answer 2

Update pip manually, first download pip:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

and then run the command

python3 get-pip.py

Now you can install with pip3

pip3 install numpy
