在 Python 中的 Visual Stdio 代碼中導入 ocrmypdf

Question

我想導入ocrmypdf 。

我已經使用pip install --upgrade --user ocrmypdf安裝了軟件包

但是當我嘗試在 VSC 中導入時：

import ocrmypdf

它捕獲了錯誤：

[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:

錯誤日志指出缺少某些依賴項，這意味着缺少 ocrmypdf 正在使用的某些模塊。 最有可能的是，它需要 teseract OCR。 嘗試安裝它，它可能會起作用。 甚至模塊的文檔也指出，模​​塊需要 tesseract 才能正常工作。
