Python 在 Visual Studio Code 中导入 ocrmypdf

Question

我想导入ocrmypdf。

我已经使用 pip install --upgrade --user ocrmypdf

安装了软件包

但当我尝试在 VSC 中导入时：

import ocrmypdf

它发现错误：

[WinError 2] The system cannot find the file specified

MissingDependencyError: 
        ---------------------------------------------------------------------
        This error normally occurs when ocrmypdf can't find the Leptonica
        library, which is usually installed with Tesseract OCR. It could be that
        Tesseract is not installed properly, we can't find the installation
        on your system PATH environment variable.

        The library we are looking for is usually called:
            liblept-5.dll   (Windows)
            liblept*.dylib  (macOS)
            liblept*.so     (Linux/BSD)

        Please review our installation procedures to find a solution:

Answer 1

错误日志指出缺少某些依赖项，这意味着缺少 ocrmypdf 使用的某些模块。最有可能的是，它需要 teserract OCR。尝试安装它，它可能会工作。甚至模块的 documentation 声明模块正常工作需要 tesseract。
