Python 3.4 has pip included, see What's New in Python 3.4.

Just execute:

python3.4 -m ensurepip

to install it if it is missing for you. See the ensurepip module documentation for further details.

    I had try it,but `Ignoring ensurepip failure: pip 6.0.8 requires SSL/TLS` , have other way?? -.-! – weijia.wang Sep 20 '15 at 11:33
  • @weijia.wang: without SSL support you won't be able to *use* `pip` anyway. How did you set up your Python 3.4 installation? Did you compile it from source? If so, you need to install the openssl header files too. – Martijn Pieters Sep 20 '15 at 11:36
  • @weijia.wang: on a Ubuntu or Debian based Raspberry you can install the `libssl-dev` package to get those headers, then recompile. See [this answer of mine](https://stackoverflow.com/questions/16447635/installing-distribute-in-python-3-3-ubuntu/16447683#16447683) for a more complete list of packages you may want to install before compiling Python. – Martijn Pieters Sep 20 '15 at 11:38

You can go to your python 3.4 directory scripts and run it's pip in:

../python3.4/scripts

You should compile python 3.4 and use venv for python3 environment:

  1. Check if you have installed required dependencies:

    sudo apt-get install build-essential

sudo apt-get install libc6-dev libreadline-dev libz-dev libncursesw5-dev libssl-dev libgdbm-dev libsqlite3-dev libbz2-dev liblzma-dev tk-dev

  2. Download and compile Python 3.4.3. You should not sudo make install it because we don't need it systemwide: 

    wget https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tgz
tar -xvf Python-3.4.3.tgz
cd Python-3.4.3 
./configure && make

    This may take a while on pi.

  3. While you still in current folder, create python environment:

    mkdir -p ~/.virtualenvs
./python -m venv ~/.virtualenvs/py34

  4. launch your virtual environment:

    source ~/.virtualenvs/py34/bin/activate

Now you have Python 3.4 and pip inside of it. Try:

    pip install bpython

To exit virtual environment use:

    deactivate
