Invalid Syntax error while installing Django in linux

Question

I am trying to install Django in linux version x86.I have already installed python. Error I am getting when executed "pip install Django" or "pip3 install Django"

$ pip install django
Traceback (most recent call last):
  File "/home/mandar/.local/bin/pip", line 7, in <module>
    from pip._internal.cli.main import main
  File "/home/mandar/.local/lib/python3.5/site-packages/pip/_internal/cli/main.py", line 60
    sys.stderr.write(f"ERROR: {exc}")
                                   ^
SyntaxError: invalid syntax

What distro are you running, and is this arm, x86, or x64? Please put more information into your questions. — CATboardBETA

EDIT 2:

I suggest you to upgrade Python to a newer version as other user has adviced. This is because f-string was added form Python 3.6 on, check this.

PEP 498 -- Literal String Interpolation.

Step 1:- Install ppa:

sudo add-apt-repository ppa:deadsnakes/ppa

Update packeges:
```
 sudo apt-get update
```
Upgrade python 2.x to python 3.6 or higher
```
 sudo apt-get install python3.6 
```
PiP installation:
```
sudo apt install python3-pip
```

Upgrade pip first (which also upgrades setuptools) and then install django again:

pip install -U pip
pip install django

Or:

pip install --upgrade pip 
pip install django

Alternative 2:

sudo python -m pip install --upgrade --force setuptools
sudo python -m pip install --upgrade --force pip
sudo pip install django==3.1

EDIT: As @Ronald Petit stated,keep this in mind:

Django 3.0+ requires python 3.6+ and you are using python 3.5, you need to either update to a newer python (recommended), or specify Django version to be 2.2 (really not recommended)

hence Run

pip install django==2.2

Django 3.0+ requires python 3.6+ and you are using python 3.5, you need to either update to a newer python (recommended), or specify Django version to be 2.2 (really not recommended)

To install an specific django version just do:

pip install django==x.x.x

x.x.x can be replaced for example with 2.2

@MandarRemane You must be still using python 3.5 as the error is marking an f string which is not available in python 3.5 but in 3.6

This is a common issue caused by an outdated version of setuptools (5.5.x).

When installing Django 1.9+ with setuptools 5.5.x, you’ll see this type of error.

It’s safe to ignore these errors (Django will still install just fine), but you can avoid them by upgrading setuptools to a more recent version. If you’re using pip, you can upgrade pip using pip install -U pip which will also upgrade setuptools.

The solution is to upgrade pip first (which also upgrades setuptools) and then install Django again:

pip install -U pip
pip install django

Pip has already dropped support for Python2 (https://pip.pypa.io/en/stable/news/). I suggest you to use older version of Pip, or to switch to Python3.6.

Syntax error near fsting means that your env doesn't support fstings (it is introduced in Python3.6

--edit--

You can isntall Python with this tutorial: https://www.2daygeek.com/install-python-3-on-centos-6/
