Fatal error in launcher unable to create process using ошибка

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:UsersMyUserNameDesktopAmppspythonpython.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__":

Issue description

I am a first time user of pip and pipenv. pipenv is failing to launch when trying to install a library. I have fully installed and updated pip, and python 3.

Expected result

Expected to have pipenv install the «requests» library. When using the pipenv install requests command. Note: I am able to get it to run when using the following command: python -m pipenv install requests

Actual result

The following is returned when attempting to run pipenv:
Fatal error in launcher: Unable to create process using '"c:python37python.exe" "C:UsersdrtriAppDataRoamingPythonPython37Scriptspipenv.exe" install requests --verbose

Steps to replicate

Run the following within cmd on windows: pipenv install requests --verbose

---

Support request:

Fatal error in launcher: Unable to create process using ‘»c:python37python.exe» «C:UsersdrtriAppDataRoamingPythonPython37Scriptspipenv.exe» —support’

Additional notes

I noticed that using python -m pipenv install requests seems to work. However, once I try and use import requests within a python script, I get a «No module names ‘requests’ found» error.

Я установил python 3.5.1 через ampps, и он работает. Однако, когда я пытаюсь использовать pip, я получаю следующее сообщение:

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

Я уже переустановил ampps в путь, который не содержит никаких пробелов. Обратите внимание, что обходной путь «python -m pip» не работает для меня, так как каждый раз, когда я его использую, я получаю следующее сообщение:

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

Как я могу заставить pip работать правильно? Надеюсь, есть способ использовать команду pip без предыдущей команды python.

EDIT: Это то, что происходит, если я пытаюсь запустить python -c "import pip.__main__":

 Python is by far one of the easiest programming languages for a complete beginner to learn. That said, it is powerful enough to be used by veterans for just about anything from computer vision to machine learning algorithms. 

In this article, we’re talking about the “fatal error in launcher: unable to create process using PiP” error in Python, its causes and what you can do to fix the problem.

---

What causes this error?

The error is generally triggered when PiP, Python’s built-in package manager cannot install a package. Common causes include:

• Corrupt Python installation.
• Outdated PiP version.
• PiP isn’t installed. 
• PiP isn’t added to your environment variables.

How to fix this?

Here are five fixes you can try out. 

Update Python and Pip

Python and its package manager Pip both get frequent updates. Using an older version can lead to problems when installing external packages like Wheel. 

While updating Python is as simple as running the command in the fix mentioned above, you can update pip by typing the following command in a terminal.

pip install upgrade

---

Update Pip dependencies

There’s also a chance that Pip’s dependencies may be causing problems. To ensure everything’s up to date, you can update setuptools and wheel using these commands once you’ve updated Pip.

pip install –upgrade wheel 
pip install –upgrade setuptools

---

Set up the environment variables

Even if Python is installed on your computer if you haven’t set up the environment variables correctly, you’re going to run into problems. Here’s how you can set the correct environment variables for Python.

Step 1: Press Windows Key + R to open the Run prompt. Type sysdm.cpl and hit enter. 

Step 2: Head over to the Advanced tab and click Environment Variables. 

Step 3: Select Path under User variables and click Edit. 

Step 4: Enter the installation paths for Python in the Edit environment variable window. The default Python installation paths for version 3.7 and above are as follows. 

C:Users<user_name>AppDataLocalProgramsPythonPython39
C:Users<user_name>AppDataLocalProgramsPythonPython39Scripts

Make sure to change the aforementioned file paths according to your Windows user name and your installed Python version. Now restart your computer, and the error should be resolved. 

---

Install packages using a Python script

You can also use a Python script to install the packages required. Here’s a small snippet showing how to install a package using a script. 

import sys
import subprocess

python = sys.executable
subprocess.check_call(
    [python, '-m', 'pip', 'install', 'package_name']
)

Make sure to replace the package_name placeholder in the script above with the name of the package you’re looking to install and you should be good to go. 

---

Run a clean install

If nothing else works, your best bet is to uninstall Python from your PC and reinstall it again from scratch. This ensures that any wrong variables or modules that might be installed in the wrong places get removed, and everything else is done from the beginning in the correct order.
