When I run pip install -U pip it doesn't install the newer version.

drahcir#Altair:~/dev$ pip --version
pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7)
Even though it says it downloaded pip 8.1.2, the pip version still says 1.5.6
How can I get pip to upgrade to 8.1.2?

I'm using mac os mojave, install python 2.7 and install pip using python get-pip.py, I already try those command to install pip :

pip install nltk
and try
sudo python -m pip install --upgrade nltk
But also result to same error like in this image
Or here in text:
error in nltk setup command: 'install_requires' must be a string or
list of strings containing valid project/version requirement
specifiers; Expected version spec in singledispatch; python_version <
"3.4" at ; python_version < "3.4"
Is it because my python version (2.7) ? But in pip ntlk page it says also support 2.7

pip install nltk success after running :
pip install --upgrade setuptools pip --user
Start with upgrading installation tools:
pip install --upgrade setuptools pip
I'm having issues upgrading pip using the pip3 install --upgrade pip3 command on Repl.it and getting this error:

You are using pip version 9.0.1, however version 19.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Pip Version
pip --version
pip 6.0.3 from /Library/Python/2.7/site-packages/pip-6.0.3-py2.7.egg (python 2.7)
jmespath-term appears to have an alternate name in the pypi index:
Doing a search with pip (pip search jmespath-term) returns:
jmespath-terminal - JMESPath Terminal
So pip install jmespath-terminal should work for you.
I am trying to get the latest version of psycopg2 on my aws instance. I noticed that the latest version was 2.4.6 but I could only get 2.0.14 on aws. Is there a way to get the latest version? There are some features I need that are not supported in the earlier versions.
This works for me in Amazon aws-cli/1.9.11 Python/2.7.10 Linux/4.1.10 and Ubuntu 14
If pip not installed in your Amazon AWS machine type:
$ sudo yum install python-pip
and then type below commands:
$ sudo yum update
$ sudo yum install libpq-dev python-dev
$ sudo pip install psycopg2
Then you will get message like below :
You are using pip version 6.1.1, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

If you need a more recent version of psycopg2 on your EC2 instance, you can install it directly with pip using: $ pip install psycopg2
You may need to first install the python-dev and libpq-dev libraries as explained in this StackOverflow question.
Working answer as of November 2022:
sudo yum install postgresql-devel python3-devel
pip install wheel
pip install psycopg2
If you are still using Python 2 then use python-devel instead of python3-devel.
The pip install wheel is not strictly necessary, but psycopg2 prefers it and it wasn't installed yet in my environment.
