How to set python installed path?

My python 2.7 was installed in /usr/local/lib. If I type which python2.7, I can have /usr/local/bin/python2.7. Then I set PYTHONPATH in ~/.bashrc as

export PYTHONPATH="/usr/local/bin/python2.7:$PYTHONPATH"

I like to install pip and virtual environment. Then tried as

sudo apt-get install python-pip python-dev python-virtualenv

When looking for python in /usr/lib I found the following error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
python-dev is already the newest version.
python-pip is already the newest version.
python-virtualenv is already the newest version.

How can I set python path properly?

EDIT: My echo $PATH gave

/usr/local/bin:/usr/local/cuda-8.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/bin/python2.7

echo $PYTHONPATH gave

/home/coie/Softwares/apollocaffe/python:/usr/local/bin/python2.7:

I deleted all python installed in /usr/local using >sudo rm -rf /usr/local/lib/python* or libpython*. Those in bin and share folder are also cleaned. Then since all program looked for python inside /usr, the installation path is set to sudo ./configure --prefix = /usr

According to https://askubuntu.com/a/250935/610294:

Try appending to PYTHONPATH instead of overwriting it completely.

Read: replace your line you added to bashrc with this:

export PYTHONPATH=$PYTHONPATH:/usr/local/bin/python2.7
