Pip - Fatal error in launcher: Unable to create process using '"'

I installed python 3.5.1 via ampps and it's working. However, when i try to use pip, i get the following message:

Fatal error in launcher: Unable to create process using '"'

I already reinstalled ampps into a path which doesn't include any whitespaces. Note that the "python -m pip" workaround doesn't work for me too, since i get the following message everytime i use it:

C:\Users\MyUserName\Desktop\Ampps\python\python.exe: Error while finding spec for 'pip.__main__' (<class 'ImportError'>: No module named 'queue'); 'pip' is a package and cannot be directly executed

How do i get pip to work properly? I hope, there is a way to use the pip command itself without the preceding python command.

EDIT: This is what happens, if i try to run python -c "import pip.__main__":

During handling of the above exception, another exception occurred:

I fixed my issue by...

  1. downloading Python 3 at the official website and installing it via express installation
  2. Copy & Paste the standalone python into the ampps/python folder and overwriting the python version provided by AMPPS
  3. running python -m pip install --upgrade pip in cmd

Now pip and python 3 are installed in their latest version.

It seems that AMPPS doesnt't provide a full-fledged python build. So you need to update python yourself.

Thanks to y'all.
