I am not able to install Apache Airflow in Windows


My attempts include:

[ here i have python 3.9 so my constraints is 3.9]

  1. I created a virtual environment and attempted to install Apache-Airflow by using pip install ‘apache-airflow==2.5.1’ / —constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.5.1/constraints-3.9.txt," but I received an error that I couldn’t understand, so I looked on the stack community for advice and learned that I needed to add -t, which I did.

  2. but then I started getting permission errors, then I went into community posts and how to fix permission errors, and it was suggested that I should run command prompt as administrator and then install unfortunately this thing isn’t working for me

  3. I’ve tried running cmd as administrator, going to my project’s directory, activating virtualenv, and installing the library, but I still get the same problem. PermissionError: [WinError 5] Access is denied: 'D:\\'

Thanks in advance.

>Solution :

Try removing the slash (/) from the command before the –constraint and then running inside the cmd terminal; it will work.

pip install apache-airflow==2.5.1 --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.5.1/constraints-3.9.txt"
