Unable to resolve dependencies for Python OCR library pypdfocr

Question

I tried installing pypdfocr using the commands:

pip install pypdfocr
pip install -i https://pypi.anaconda.org/pypi/simple pypdfocr

but I constantly get an error message:

File "C:\Users\888537\AppData\Local\Temp\pip-build-b4mwr93n\evernote\setup
.py", line 6
        exec x
             ^
    SyntaxError: Missing parentheses in call to 'exec'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\888537\A
ppData\Local\Temp\pip-build-b4mwr93n\evernote\

The following is the installation log:

How can I fix this installation problem using pypdfocr library?

Answer 1

Use Python 2.x instead of 3.x, or find a line with a syntax error and add parentheses.

See in Python 3 exec is a function, but in Python 2 exec is a command.

So, in Python 3, you have to put the arguments in brackets to properly call exec ().

So, you are trying to install a package in Python3 designed for Python 2.

At least there is a script installation.

PIP, , , , setup.py, python setup.py.

, script Python 2, , Python 2. pip Python.

- Anaconda.
