Can't install tesserocr using pip on buster docker

问题

以下是您的Dockerfile的翻译部分：

  1. FROM python:3.11-buster AS app
  3. WORKDIR /srv/app
  5. ENV PYTHONPATH /srv/app
  7. RUN apt update -y && \
  8.     apt install -y libegl1 libgl1 libxkbcommon-x11-0 dbus tesseract-ocr liblept5 leptonica-progs libleptonica-dev libtesseract-dev
  9. RUN pip install --upgrade pip

您在容器中运行pip install tesserocr时遇到错误。要解决这个问题，建议尝试以下步骤：

  1. 确保您的Docker容器中已安装了tesseract和leptonica等依赖项，这些是tesserocr的依赖项。

  2. 检查您的Python版本是否与tesserocr兼容。某些版本的tesserocr可能不兼容特定的Python版本。您可以尝试更改Python版本或tesserocr版本。

  3. 如果可能，查看tesserocr的文档或GitHub存储库，了解是否有与您的Python版本和依赖项版本匹配的建议安装方式。

  4. 如果问题仍然存在，您可以尝试在Dockerfile中的pip安装之前添加一个步骤，将tesserocr从系统包管理器中安装，以确保所有依赖项都已正确安装。

希望这些步骤能帮助您解决问题。

以下是您要翻译的内容：

"I was suffering from the same issue you were, hopefully this is helpful still:

I believe the dependencies for tesserocr are not correctly met with the default packages in the repositories for buster.

Case in point, the apt repository information for Buster suggests tesseract-ocr version 4.0.0-2, and version 5.3.0-2 for the bookworm version. When I run the minimum failing example below in Docker, I receive error output suggesting some kind of incompatibility between tesserocr and tesseract: tesserocr.cpp:22550:14: error: ‘TessAltoRenderer’ is not a member of ‘tesseract’.

However, the working dockerfile requires only an upgrade to bullseye from buster. I believe this has something to do with dependencies, and without a ton of research I'm not sure I'd be able to figure out what specifically has changed, but my suggestion is to upgrade from buster to at least bullseye. I tested it on bookworm as well, and it works (which also lets you use tesseract version 5+).

Here is a Dockerfile which fails to build:

  1. FROM python:3.11.4-buster
  3. WORKDIR /app
  5. RUN apt-get update && apt-get install -y \
  6.   libleptonica-dev \
  7.   tesseract-ocr \
  8.   libtesseract-dev
  10. RUN pip install tesserocr
  12. RUN mkdir src && \
  13.   echo "from tesserocr import PyTessBaseAPI" >> ./src/main.py && \
  14.   echo "with PyTessBaseAPI() as api:" >> ./src/main.py && \
  15.   echo "  print(api.Version())" >> ./src/main.py 
  17. ENTRYPOINT ["python", "./src/main.py"]

Here is a Dockerfile which succeeds to build, and run:

  1. FROM python:3.11.4-bullseye # Also tested with -bookworm
  3. WORKDIR /app
  5. RUN apt-get update && apt-get install -y \
  6.   libleptonica-dev \
  7.   tesseract-ocr \
  8.   libtesseract-dev
  10. RUN pip install tesserocr
  12. RUN mkdir src && \
  13.   echo "from tesserocr import PyTessBaseAPI" >> ./src/main.py && \
  14.   echo "with PyTessBaseAPI() as api:" >> ./src/main.py && \
  15.   echo "  print(api.Version())" >> ./src/main.py 
  17. ENTRYPOINT ["python", "./src/main.py"]
