image_to_string在Mac無法正常工作

我試圖在Mac Maverick中遵循pytesser（link）的這個例子。image_to_string在Mac無法正常工作

>>> from pytesser import * 
>>> im = Image.open('phototest.tif') 
>>> text = image_to_string(im)

但是，在最後一行我得到這個錯誤信息：

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "pytesser.py", line 31, in image_to_string 
    call_tesseract(scratch_image_name, scratch_text_name_root) 
    File "pytesser.py", line 21, in call_tesseract 
    proc = subprocess.Popen(args) 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 711, in __init__ 
    errread, errwrite) 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1308, in _execute_child 
    raise child_exception 
OSError: [Errno 2] No such file or directory

但是，我不明白我應該做的。文件phototest在我運行腳本的同一個文件夾中。如何解決這個問題？

UPDATE：

當我嘗試

brew install tesseract

我得到這個錯誤：

Warning: It appears you have MacPorts or Fink installed. 
Software installed with other package managers causes known problems for 
Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again. 
Error: You must `brew link libtiff libpng jpeg' before tesseract can be installed

它看起來像你的腳本有一個啓動過程中的問題......它看起來像https://code.google.com/p/pytesser/wiki/描述了同樣的問題自述文件發行版隨附Windows可執行文件，在Mac上無法使用。正如那裏提到的Linux人員，您可能需要提供一個tessact可執行文件。 – Luis

明白了。但我可以這樣做嗎？ –

我確定它是可行的，但我不知道詳細信息：應爲tessact用戶標記問題。 – Luis

其實我有同樣的錯誤，你，這是我發現這個職位。我也解決了我的問題，因爲你把它給了我！

我看到：

ryan.davis$ python tesseract.py 
Traceback (most recent call last): 
    File "tesseract.py", line 52, in <module> 
    print (image_to_string(big)) 
    File "/usr/local/lib/python2.7/site-packages/pytesseract/pytesseract.py", line 161, in image_to_string 
    config=config) 
    File "/usr/local/lib/python2.7/site-packages/pytesseract/pytesseract.py", line 94, in run_tesseract 
    stderr=subprocess.PIPE) 
    File "/usr/local/Cellar/python/2.7.10_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 710, in __init__ 
    errread, errwrite) 
    File "/usr/local/Cellar/python/2.7.10_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1335, in _execute_child 
    raise child_exception 
OSError: [Errno 2] No such file or directory

想知道什麼，我不得不這樣做，以解決這一問題？正是你試過的：brew install tesseract我已經安裝了tesseract python庫，但沒有在系統級安裝它。這樣就解決了我的問題。那你的怎麼樣？

我想你可能已經分心本：

Warning: It appears you have MacPorts or Fink installed. Software installed with other package managers causes known problems for Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again.

而沒有注意到你的答案在BREW響應已提供：

You must brew link libtiff libpng jpeg before tesseract can be installed.

所以做：

brew link libtiff 
brew link libpng 
brew link jpeg

Then：

brew install tesseract

最後：

:)
