and nothing happened anymore.
what shoule I do?

Check that you have gcc and python-devel installed. If not (Assuming a Redhat derivative, something similar for others)
sudo dnf install gcc
sudo dnf install python3-devel
The pip installation seems to access some system files, despite being installed with --user, so you may have to:
sudo pip3 install --user ibm_db
You can find more info at: pypi

pip is showing that its upgraded but it's not?

I am trying to install pygame on my pc but the process was getting finished by exit code -1. So some people recommended to upgrade it (my old one was 7.1.0) After upgrading, I am still seeing 7.1.0
Command:
pip install --upgrade pip
What I got
You are using pip version 7.1.0, however version 21.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' comm
and.

Successfully installed pip-7.1.0
So I mean that pip is still stuck at 7.1.0 instead it should have jumped to the latest??*
Now when i try to see pip version by typing:
pip --version
it returns
pip 7.1.0 from c:\python34\lib\site-packages\pip-7.1.0-py3.4.egg (python 3.4)

Run the following command:
$ python -m pip install --upgrade pip

pip install --upgrade pip isnt upgrading pip

I'm trying to upgrade pip on Centos 7. I pip 8.1.2 from /usr/lib/python2.7/site-packages (python 2.7) installed.
When I run pip install --upgrade pip --user I get the following output:

You are using pip version 8.1.2, however version 19.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
What I've tried
I've tried the following, which have all resulted in the same output and result as above:
pip install --upgrade pip --user
pip install -U pip --user --ignore-installed
pip install -U pip --user --ignore-installed --no-cache-dir
sudo yum update pip which returns
No Match for argument: pip
No package pip available.
No packages marked for update
sudo yum update python-pip which returns No packages marked for update
Observations
python -m pip --version outputs:
pip 19.3.1 from /home/deploy/.local/lib/python2.7/site-packages/pip (python 2.7)
pip --version outputs:
pip 8.1.2 from /usr/lib/python2.7/site-packages (python 2.7)

You need to update your PATH to include /home/deploy/.local/lib/python2.7/bin before /usr/lib/python2.7/bin if you want pip to resolve to the same location as python. Otherwise, python -m pip is the more proper usage pattern
Otherwise, you're looking at two completely separate python installations and pip is indeed upgraded in one of them
Note: Python2 is end of life, so probably best to remove the one in your home folder, anyway, and switch to using something like Pipenv or pyenv

Why does my numpy install keeps being KILLED?

here's what I am trying to do on Coding Ground
sh-4.3$ pip install --target=. virtualenv

Why does my trying of installation of numpy keep being killed?
And how do i solve this problem?

A quick fix for this would be to add swap memory. Here's an Ubuntu example:
sudo mkdir /media/fasthdd
dd if=/dev/zero of=/media/fasthdd/swapfile.img bs=1024 count=1M
sudo mkswap /media/fasthdd/swapfile.img
sudo swapon /media/fasthdd/swapfile.img
Don't forget to turn it off if you don't need it.

pip install --upgrade pip installs the same version

Somehow pip --upgrade doesn't upgrade any packages.
I'm on OSX El Capitan (10.11.3) and installed python using brew install python
Python: /usr/local/bin/python# -> ../Cellar/python/2.7.11/bin/python
Pip: /usr/local/bin/pip# -> ../Cellar/python/2.7.11/bin/pip
After successful install I run pip install --upgrade pip.
Full output:
$ pip install --upgrade pip

Why doesn't pip install the new version?
Update
I think it has something to do with my ~/.pydistutils.cfg file which fixes the DistutilsOptionError: must supply either home or prefix/exec-prefix -- not both error when running pip. I followed these instructions

Getting annoyed by things not working I created a new OSX profile. In the new profile everything was working fine so after investigating further I found a file ~/Library/Application\ Support/pip/pip.conf in my main profile containing:
[global]
target=/usr/local/lib/python2.7/site-packages
I don't know how it got there but removing it resolved the issue.
This also resolved the need for the ~/.pydistutils.cfg file.
