Python:OSError:[Errno 2]没有这样的文件或目录

Question

我使用pytesseractlib从图像中提取文本.当我在localhost上运行代码时,这工作正常.但是当我在openshift上部署时,会给我上面的错误.

下面是我到目前为止所编写的代码.

try:
  import Image
except ImportError:
  from PIL import Image
import pytesseract
filePath = PATH_WHERE_FILE_IS_LOCATED # '/var/lib/openshift/555.../app-root/data/data/y.jpg'
text = pytesseract.image_to_string(Image.open(filePath))  # this line produces error

以上错误的追溯是

>>> pytesseract.image_to_string(Image.open(filePath))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/var/lib/openshift/56faaee42d527151d5000089/app-  root/runtime/repo/pytesseract/pytesseract.py", line 132, in  image_to_string
boxes=boxes)
File "/var/lib/openshift/56faaee42d527151d5000089/app-root/runtime/repo/pytesseract/pytesseract.py", line 73, in run_tesseract
stderr=subprocess.PIPE)
File "/opt/rh/python27/root/usr/lib64/python2.7/subprocess.py", line 710, in __init__
errread, errwrite)
File "/opt/rh/python27/root/usr/lib64/python2.7/subprocess.py", line 1327, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

但Image.open(filePath)返回对象引用

 <PIL.PngImagePlugin.PngImageFile image mode=RGBA size=1366x768 at 0x7FC5A9F719D0>

如何删除此错误？提前致谢!!

要么您没有在“openshift”上安装 tesseract-ocr，要么它不在您的 PATH 中。请参阅https://pypi.python.org/pypi/pytesseract/0.1 检查是否可以从命令行执行 tesseract 命令。
