Permission Denied Error in Python PIP Install

When attempting to install or update packages using PIP in Python 3.4 on Windows 8.1, you may encounter a "PermissionError: Access is denied" message. This error indicates that you do not have sufficient permissions to access the files involved.

Solution:

To resolve this issue, it is necessary to elevate your command prompt to run as Administrator. While your account may have administrative permissions, running the command prompt as a standard user may still result in access restrictions.

Steps:

1. Open the Start menu and search for "cmd".
2. Right-click on "cmd.exe" and select "Run as Administrator".
3. In the elevated command prompt, execute the following command to upgrade PIP:

python -m pip install --upgrade pip

4. Alternatively, you can install specific packages by using the --user flag to install them in your user directory instead of the global Python directory:

python -m pip install --user <package_name>

Additional Note:

It is generally recommended to avoid installing Python packages globally unless absolutely necessary. For optimal project management, it is preferable to utilize virtual environments, such as virtualenv, to isolate your Python packages within specific projects.
