Pip - Fatal error in launcher: Unable to create pr

Question

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:

Answer 1

The fastest way is:

python -m pip install pip==9.0.0

If you want the latest pip, you can run

pip install -U pip

afterwards.

Answer 2

It happened to me using pip package, then I solved it like below:

1) First of all uninstall pip using python command

$python -m pip uninstall pip

2) Then reinstall pip package using easy_install command

$easy_install pip

3) Finally, try again pip command on command line directly, install any package

$pip install pylint

or only execute pip command

$pip

Answer 3

I solved it by following the steps from this website https://www.sysrecon.com/programming/python-pip-how-to-get-around-fatal-error-in-launcher-unable-to-create-process-using/

Update pip using: python -m pip install -U pip from command line after you've located the right directory in which python is installed in your machine.
