This error popped up today while trying to install some packages using pip. Python version - 3.5.4

pip install pytesseract

It gives the following exception :

Collecting pytesseractException:

This exception comes up even for pip update commands. html5lib version is 0.999. The following code seems to be working fine.

import html5lib
document = html5lib.parse("<p>Hello World!")

Any pointers as to why this error is coming up would be helpful. Thanks in advance.

  • I ran into the same issue on a different package--and reinstalled `pip` and `html5lib` with no effect. As a workaround, you can try installing from source (or using a wheel file if available): `git clone git@github.com:madmaze/pytesseract.git` and `python setup.py install`. – David C Oct 23 '17 at 17:00
  • Yes I did manage to install it from the source. But my pip is useless now. Will reinstall and see. – msr Oct 24 '17 at 06:21

I was using anaconda and recently updated conda and anaconda and I recieved this error.

'conda update pip' fixed it

  • It seems to be working now. Thank you:) I remember trying out `conda update anaconda` and `python -m pip install --upgrade pip`. Didnt work out then. Thank you:) – msr Nov 05 '17 at 06:38
