INSTALL PYTHON AND DEPENDENCIES

To install python in your development environment. you can follow these steps.

• Download Python via console.

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ wget https://www.python.org/ftp/python/3.10.2/Python-3.10.2.tgz

• Extract the downloaded archive by running the following command:

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ tar -xvf Python-3.10.2.tgz

Navigate to the extracted directory by running the following command:

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ cd Python-3.10.2

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ ./configure --enable-optimizations

Build and install Python 3.10 using the following command:

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ make

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ sudo make altinstall

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ python3.10.2 --version
Python 3.10.2

NOTA: if you have problem in you environment getting an response as "(main) $ python --version Python 3.10.4" you need to apply this command to resolve the problem.

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON/Python-3.10.2]$ ls /usr/local/bin/python*
/usr/local/bin/python3.10  /usr/local/bin/python3.10-config
[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON/Python-3.10.2]$ sudo ln -s /usr/local/bin/python3.10 /usr/local/bin/python3.10.2
[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON/Python-3.10.2]$ python --version
Python 3.10.4
[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON/Python-3.10.2]$ python3.10 --version
Python 3.10.4
[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON/Python-3.10.2]$ python3.10.2 --version
Python 3.10.2

Then you can create your environment normal...

CREATE VENV PYTHON 3.10.2 WITH PyATS

Note: PyATS just available in environments over Linux.

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ python3.10 -m venv inventory

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ cd inventory

[opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ source inventory/bin/activate

(inventory) [opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ python --version
Python 3.10.2

In this environment the version of python is Python 3.10.2

(inventory) [opc@jenkins-master 00_AUTOMATING_A_NETWORK_INVENTORY_WITH_PYTHON]$ pip list
