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__":

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Answer 1

Check the file name, in the path whether it is just pip or pip2.7.exe

in that case rename the file to pip.exe then run pip command.

Answer 2

I got this error while running the command using pip3. I have python 3.6 installed on windows. I was trying this-

pip3 install PACKAGENAME

It gave error. The solution in this particular case is simply to run the command as pip.

pip install PACKAGENAME

Answer 3

My solution is quite simple, i faced the same problem

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

the solution was to change the path from where i am running pip.

Answer 4

run this python code:

import pip
pip.main(['install','flask']) # replace flask with the name of module you want to install

If you need to install multiple modules from a requirements.txt file,

import pip
fo = open("C:/...../requirements.txt", "r")
inp = fo.read()
ls =inp.split()     

for i in ls:
    pip.main(['install',i])

Check your Windows PATH environment variable. It has a limit of 260 characters and your python location might be past that character limit.

You can either move your Python paths higher in the path list or disable the Windows character limit as described here: https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx

A registry key allows you to enable or disable the new long path behavior. To enable long path behavior set the registry key at HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled (Type: REG_DWORD). The key's value will be cached by the system (per process) after the first call to an affected Win32 file or directory function (list follows). The registry key will not be reloaded during the lifetime of the process. In order for all apps on the system to recognize the value of the key, a reboot might be required because some processes may have started before the key was set.

The registry key can also be controlled via Group Policy at Computer Configuration > Administrative Templates > System > Filesystem > Enable NTFS long paths.

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.
