1. Create a Python virtual environment

Python2 and Python3 are already installed in Fedora, and the executable directory is in the/usr/bin/directory, where the soft connection is

python->python2python2->python2.xpython3->python3.x

The next step is to use Python3 to operate MongoDB, so as to not pollute the original system environment, and isolate this particular application, the use of Python virtual environment.

Create a virtual environment

Grammar

$ python3 -m venv /path/to/new/virtual/environment

Example

$ python3 -m venv py3mongodb或者$ python3 -m venv ~/py3mongodb

The directory for the Python virtual environment will be generated when execution is complete, py3mongodb.

Using the specified virtual environment

Grammar

$ source <venv>/bin/activate

Example

$ source py3mongodb/bin/active或者$ source ~/py3mongodb/bin/active

The result of executing the "which python" command at this time is ~py3mongodb/bin/python
The result of executing the "python-v" command at this time is Python 3.x.x

Exiting the current virtual environment

Grammar

$ deactivate

Python's Virtual Environment reference:

Https://docs.python.org/3/library/venv.html#module-venv

2. Install the MongoDB python driver

Online installation
Recommended PIP Installation

$ python -m pip install pymongo

Upgrade Pymongo

$ python -m pip install --upgrade pymongo

SOURCE Installation
Premise Dependent installation
With C extension dependent

$ sudo yum install gcc python-devel$ git clone git://github.com/mongodb/mongo-python-driver.git pymongo$ cd pymongo/$ python setup.py install

Does not include C extension dependencies

$ python setup.py --no_ext install

For more official details, see the official MongoDB documentation.
