Pip - Fatal error in launcher: Unable to create process using '"'
I fixed my issue by...
- downloading Python 3 at the official website and installing it via express installation
- Copy & Paste the standalone python into the ampps/python folder and overwriting the python version provided by AMPPS
- running
python -m pip install --upgrade pipin 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.
The same error, but in a different situation. I have a virtual environment, in which I ran, in the VE's \Scripts directory where pip.exe is:
pip freezeI got the error message
Fatal error in launcher: Unable to create process using '"'There is no space in my VE path (google that error). Then I tried python -m pip install --upgrade pip and got
Requirement already up-to-date: pip in o:\upsdowns\flask\lib\site-packagesso then I tried
python -m pip freezeand that worked. I think it might be a path issue in the VE, but I'm OK with this workaround.
I'm adding this here because this page is high up when you google that errormessage. In other words, I didn't make a new question, even though my situation is quite different from the OP's. Possibly even, I got into that situation because I didn't add modules to the virtual environment "properly".
Anyway, I hope it helps some.
This worked for me under Windows 10 x64:
Ensure that the Python directories are in the path, e.g.:
# Edit Environment variables so that variable "path" points to the new location.# Insert these at the start of the list (or delete other Python directories), as Windows takes the first match it finds.# Run the program "Edit the System Environment Variables".# Or see Control Panel under "System Properties".S:\Research\bin\Python375\Scripts\S:\Research\bin\Python375\Then:
python -m pip install --upgrade --force-reinstall pipIn my particular case, the error was caused by shifting the Python directory to a new location.
