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.

I use a mac and I switched from python2 to python3 recently. Post doing that I couldn't install jupyter on my laptop due to some dependency issues. After a lot of trial and errors, I just uninstalled Python 3 and installed it with brew instead.
I used the following guides to uninstall 1, 2.
Post that I installed jupyter again and now I'm facing this issue:
$ pip install --index-url '..' --trusted-host '..' jupyter
This is how I usually install packages on my laptop behind a firewall and it works. But now I'm getting the following exception:

I have set the proxy and it can be seen using env. I've also tried:

export https_proxy="https://<hostname>:<port>"
Nothing seems to be working.
Any suggestions would be helpful.
In the end, what helped was unset https_proxy http_proxy.

Can anyone tell me what's wrong and how can I fix it? I have Python 2.7.12 running.
You have to run the command without sudo:
pip install cassandra-driver
It's a permissions issue with the .cache directory. Try running the command with sudo -H

I'm not using any proxy or firewall (unless you count my router as both, idk).
This happens to me when I am behind a corporate proxy. To fix that, run with --proxy=urlOfYourProxy.
For example:
pip install --proxy user:password#http://localproxy:8080

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.
