Overcoming "pip install" Access Denied Error on Windows

Installation using pip can be a straightforward task, but occasionally you may encounter an access denied error on Windows, even when running Command Prompt or PowerShell as Administrator.

This error commonly manifests as:

WindowsError: [Error 5] Access is denied: 'c:\users\bruno\appdata\local\temp\easy_install-0fme6u\cryptography-0.9.1\.eggs\cffi-1.1.2-py2.7-win-amd64.egg\_cffi_backend.pyd'

To overcome this issue and successfully install packages using pip, follow these steps:

Command Prompt (Admin)

1. Open Command Prompt as Administrator.
2. Navigate to a suitable directory for the installation, typically your Python installation directory (e.g., C:Python38).

3. Run the following command, replacing mitmproxy with the desired package name:

   python -m pip install mitmproxy

   Copy after login

This method should grant necessary permissions to complete the installation. If the error persists, you may consider checking if your antivirus software is interfering with the pip installation process.
