Fatal error in launcher: Unable to create process using '""c:\program files\python 3.6\python.exe" "C:\Program Files\Python 3.6\Scripts\pip.EXE" '

[AndrewUshakov]

• Pip version: 10.0.0
• Python version: 3.6.5 64 bit
• Operating system: Windows 7 Ultimate, Service Pack 1, 64-bit

Description:

After upgrading pip to the version 10.0.0 (from Pycharm, that is using pip as a package) any attempts to start updated pip cause an error:

Fatal error in launcher: Unable to create process using '""c:\program files\python 3.6\python.exe" "C:\Program Files\Python 3.6\Scripts\pip.EXE"'

Command python -m pip works as expected.

I found text "Fatal error in launcher" only in executables:
src\pip_vendor\distlib\t32.exe
src\pip_vendor\distlib\t64.exe

and in the pip.exe itself.

After

python -m pip uninstall pip
easy_install.exe pip

error disappeared.

It is interesting, that initially pip.exe had almost the same size as t64.exe, now it significantly shorter.
