Python 3.7 - PIP upgrade error on windows 10

I tried to update PIP (Windows 10, Python 3.7.1) in console using command:
python37 -m pip install --upgrade pip
This is an error I got everytime I try to update it:
>Exception:

Surprising fact - I had succesfully updated PIP on Python 2.7 isntance without any problems.

I faced this error while trying to upgrade from pip version 18.1 to 19.0.3.
After a lot of search I hit the solution at https://packaging.python.org/tutorials/installing-packages/
(If that still doesn’t allow you to run pip:
Securely Download get-pip.py [1]
Run python get-pip.py. [2] This will install or upgrade pip. Additionally, it will install setuptools and wheel if they’re not installed already.)
The link there takes you to:
Use https://bootstrap.pypa.io/get-pip.py
Download and save the file, run it from command prompt. It worked like a charm for me.

You can try:
python -m pip install -U --force-reinstall pip

How to correct my python3 environment on Ubuntu 16.04 (64 bit)

I tried to install the mysql connector for my python environment.
I use python on my Linux (Ubuntu 16.04) machine.
On this machine python 2.7.12 and python 3.5.2.
I probably messed something up because of my inexperience with installing new python modules.
When I now try to install the mysql connector with the command
pip3 install mysql-connector-python-rf
I get the following messages:

How can a correct this problem?
Or How can I do a correct fresh install of my python2 and python3 environment on my Ubuntu 16.04 x86 Linux?

There is nothing wrong with your installation. To install packages globally, you need superuser privileges; you would run that command under sudo.
However, you should avoid doing this. Create a virtualenv and install the package there.

pip install for windows running into anaconda error

I am trying to pip install pyrtlsdr for the software defined radio RTL-SDR (RTL2832U), but am running into issues with anaconda I believe. I am receiving two errors in cmd, although I am getting the same response through cygwin and cmder. I am running the following command:
pip install pyrtlsdr
However, when I run this command, I see the following error:
pip install pyrtlsdr

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip'
command.
What exactly is wrong here? I do not know how to force privileges in this file that I think is causing issues, additionally, I also do not know why I am receiving the same error when I run the suggested upgrade in this error.

Try running the cmd line as administrator, this should give write privilege to C drive.

Python: permission denied error when installing pip

I am a student and I am doing project on department computer, system Linux 7.2. Now I am trying to install pip so that I can install python packages using it.
I have downloaded get-pip.py and tried to install via python get-pip.py. It gives me:

Then, I tried to install using sudo python get-pip.py, however, I got "xxx is not in the sudoers file. This incident will be reported."
So, I was wondering whether I don't have the permission to root and don't have the right to do sudo...but I am not sure about this...
Any suggestion to fix this problem? And in the end, I want to install scipy and gensim.

Does the system hand you a virtualenv command?
Then you should read about virtualenvs. Comes in handy anyhow.
If not you may use the approach by Jasper van den Bosch

You either need to use a virtual environement, and install the pip package in the virtual env. Or install it with pip globally ie system wide as root user

Try install pip using easy_install
Try Below commands in terminal:
sudo su
easy_install pip

permission denied pip virtualenv

I have been trying to set up virtualenv for use with django, but I keep having issues installing virtualenv with pip.

The closest answer I can find regards permissions inside the virtualenv: How to avoid "Permission denied" when using pip with virtualenv
But from what I can tell my issue is that there's something wrong with my install of pip, since I apparently don't even have virtualenv yet.

I don't think there's anything wrong with your pip installation. virtualenv is itself a Python module, and by default it goes in /usr/local/lib/python2.7/dist-packages, a folder for which your user does not have write permissions. If you have sudo access, it would be easiest to simply try:
sudo pip install virtualenv
Once you've done that, you should be able to create virtualenvs without needing to use sudo. Alternately, there are instructions here for making your own virtual environment, but it looks like you will likely need to do some manual editing of the script it directs you to download.
