I get a fatal error when using pip install.

pip install praw
Fatal error in launcher: Unable to create process using '""c:\program files\python36\python.exe"  
"C:\Program Files\Python36\Scripts\pip.exe" install praw'

But when i do the samething but with Python in beginning, it works they way as it used to when using just pip install. 

python -m pip install praw

I have no idea whats causing this issue and I'm not sure how to fix this. Fatal error in launcher: Unable to create process using ""C:\Program Files (x86)\Python33\python.exe" "C:\Program Files (x86)\Python33\pip.exe"" gives a workaround and not a fix.

  • Its answer provides only a workaround and not an actual fix. – Naveen Apr 16 '18 at 08:50
  • The point abut a duplicate question is that it has been asked before, it does not mean there is a fix, often there is no fix. – cdarke Apr 16 '18 at 09:00
  • I just want to understand why this issue is happening. It was working fine before and now its not. Wherever i searched, it had this workaround only. Not sure what changed. – Naveen Apr 16 '18 at 09:02

    pip 10.0.0 just came out, I expect that's what changed for you. When I updated, I get the same error now. The python -m workaround still works, but this isn't the first time this specific bug has been introduced. I expect to have to wait until a new pip release for it to be resolved. – BlivetWidget Apr 16 '18 at 19:27
  • @BlivetWidget Can confirm, just updated and now have this problem – Oisin Apr 16 '18 at 22:06

It's possible your problem is caused by this issue introduced in pip 10.0.0: https://github.com/pypa/pip/issues/5223

Your options are limited to waiting for a maintenance release (which shouldn't be too far off since the underlying bug https://bitbucket.org/pypa/distlib/issues/104/generated-wrapper-scripts-fail-when-python has already been fixed) or downgrading to pip 9.

  • I checked and I do have pip 10.0.0. I have a script that is automatically updating all python modules in the background on a schedule. Probably this was upgraded at that time.. – Naveen Apr 18 '18 at 12:04
