无法安装tesseract-ocr软件包-``在/ tmp / pip_build_root / tesseract-ocr中编译失败，错误代码为1''

Question

Trying to install tesseract-ocr package for use with pytesseract, running into an odd issue. Installing everything else with pip worked, but when I tried sudo pip install tesseract-ocr as instructed here , I get the following errors:

Command /usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/tesseract-ocr/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-zsaPkE-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/tesseract-ocr
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    load_entry_point('pip==1.5.4', 'console_scripts', 'pip')()
  File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 235, in main
    return command.main(cmd_args)
  File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 161, in main
    text = '\n'.join(complete_log)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 42: ordinal not in range(128)

I have a feeling that the traceback is causing the UnicodeDecodeError. Does anyone have any ideas on how to resolve this?

The link provided only mentions the use of Pip for installing pytesseract not Tesseract-OCR.

As mentioned you will also need the Python Imaging Library (PIL), if it is not installed in your system you can use Pillow by using sudo pip install pillow .

Tesseract-OCR is not installed with Pip using sudo pip install tesseract-ocr since it is not a Python module like pytesseract. From what I see Tesseract-OCR is written mostly in C++.

The link given, http://code.google.com/p/tesseract-ocr/ , is no longer hosting Tesseract-OCR as the project has been moved to https://github.com/tesseract-ocr/tesseract .

Install instructions can be found on https://github.com/tesseract-ocr/tesseract/wiki .

For Linux use, sudo apt-get install tesseract-ocr or sudo apt-get install tesseract-ocr-all to install all languages.

For Mac use, brew install tesseract or brew install tesseract --all-languages to install all languages. You will need Homebrew installed, it can be found at https://brew.sh .

For Windows, installer can be found on https://github.com/tesseract-ocr/tesseract/wiki/Downloads/ . Current stable version should comes with all languages included.
