I have pip installed for python3:

$ pip3 -V
pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.4)

If I try to upgrade to Version 8, this is what I get:

$ sudo pip3 install --upgrade pip

Not uninstalling pip at /usr/lib/python3/dist-packages, owned by OS

Cleaning up...

Can anyone tell me why it won't upgrade to a newer version?

  • I get the same result if I add sudo: `$ sudo pip3 -V: pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.4)` – Rotareti May 15 '16 at 05:10
  • i try it on my laptop and got the same error as yours but when i check pip3 version with root permission i can see the new updated version please try to close your current terminal and open a new one and try it with su – Nitish shah May 15 '16 at 05:15
  • I just restarted my machine and it is still the same. – Rotareti May 15 '16 at 05:19
  • please post the output of python3 --version – Nitish shah May 15 '16 at 05:25
  • $ python3 --version: Python 3.4.3 – Rotareti May 15 '16 at 05:27
  • i don't know why its not working in your device. – Nitish shah May 15 '16 at 05:30
  • Other people have recommended `sudo -H` from your home directory, which I believe is necessary because the system candidates have lower priority than the user ones. Using `sudo -H` there *should* be no ambiguity with another location/version, but it also sounds like the packaged version is not synchronized with Python's version. They'll contradict and subtly override one another based on who/where you are at the moment, but at the maintenance level there's no conflict, so the user must know best. A warning might be nice. – John P Jan 22 '18 at 05:03

  • Anaconda looks interesting! But for now I'd like to stick to virtualenv and pip. Maybe I'll give it a shot on my next project. – Rotareti May 15 '16 at 06:01
  • Anaconda install a lot of packages and some features as Jupyter Notebook. It's very easy to install and you save a lot of time. In other words, it prepares a nice pyhton environment. Take it a try. – Vitor Abella May 15 '16 at 06:05
