edit

To install packages using the MinGW-w64 compiler on Windows 7 through pip, follow these steps:

1. First, make sure that you have installed the MinGW-w64 compiler on your system. You can download it from the official website and install it using the installer.

2. Open a terminal/command prompt and navigate to the folder where you want to install the package. You can do this by using the cd command followed by the folder path.

3. Once you are in the folder, you can use the following command to install the package using pip:

   pip install --global-option=build_ext --global-option="-I${MINGW_PREFIX}/include" --global-option="-L${MINGW_PREFIX}/lib" <package-name>
   

   In this command, replace <package-name> with the name of the package you want to install.

4. The --global-option=build_ext option is used to tell pip to use the MinGW-w64 compiler to build the package.

5. The --global-option="-I${MINGW_PREFIX}/include" option is used to tell pip where to find the MinGW-w64 include files.

6. The --global-option="-L${MINGW_PREFIX}/lib" option is used to tell pip where to find the MinGW-w64 libraries.

7. Once you run the command, pip will download and install the package using the MinGW-w64 compiler.

8. You can verify that the package has been installed correctly by importing it in a Python script or in the Python interpreter.
