Error when installing any package in python

since I wanted to install pyserial, I always get these Errormessages when installing any package with pip-installer. I checked every similar case on Stackoverflow and other Hubs, but nothing of their solutions worked for me. Anyway, i want to install python2.7 Addons on a Debian Linux (Embedded System) by using a proxy.
Thank you for your help in advance.
Best regards

If reinstalling pip doesn't fix your issue, look if you can update your Debian distro. They are using a modified pip which is causing the issue.

It looks like reinstalling pip should fix your issue. Since you're on an Linux machine, just run these commands:
apt-get remove python-pip
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py

Reinstall or Modify Your pip.

Tensorflow with raspberry pi 2

I tried to install the tensorflow but I got an error message which is a memory error.
pip3 install --user --upgrade tensorflow
After I found a solution for that Link. I use sudo command additionally.
sudo pip3 install --no-cache-dir tensorflow
Tensorflow was installed successfully for python 3.5.3 in raspberry pi 2.
When I tried following command which is recommended in google installation guide it is not working.
python3 -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"
Error massage:
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named 'tensorflow'
After that, I tried to import tensorfolw library in Thonny (import tensorflow as tf) but I got following error message.
/usr/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: compiletime version 3.4 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.5

/usr/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: builtins.type size changed, may indicate binary incompatibility. Expected 432, got 412
return f(*args, **kwds)
How to solve this error for raspberry pi?
Updated.
I tried to install again using sudo pip3 install --no-cache-dir tensorflow I got following error.

I think I have solved my problem. I installed anaconda on ubuntu 16.04, but I didn't set the path. Now I added PATH=$PATH:$HOME/anaconda2/bin to .bashrc. Then anaconda works fine. Because anaconda already includes h5py module.
