WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

据我所知，我提供了所需的所有信息，如果缺少某些信息，请告诉我。
我是自制程序新手，但使用过 Linux 操作系统一段时间
还有一种方法我可以从 Github 或任何存储库直接在自制程序上安装，就像如果在 git 存储库文件中进行了一些更改，我想直接安装它们，否则需要等待 tar.gz 或 .dmg 文件的 realese
无法从 pip 安装 tesserocr。事实上，构建状态被标记为failing，正如您在 PyPI 链接here上看到的那样。
因此要安装它，您需要使用以下行进行 conda 安装：
conda install -c conda-forge tesserocr
此外，您需要使用 Homebrew 安装 tesseract，如下所示：
brew install tesseract
现在，如果您尝试运行脚本，可能会出现新错误，表明未找到某些 dylib。
为了解决这个新问题，您需要创建符号链接（即符号链接）。就我而言，我需要创建那些：
注意：在执行以下几行之前，请检查 /usr/local 中是否有名为 lib 的文件夹，如果没有则创建它
ln -s /opt/homebrew/Cellar/libarchive/3.6.2_1/lib/libarchive.13.dylib /usr/local/lib/libarchive.19.dylib
ln -s /opt/homebrew/Cellar/leptonica/1.82.0_1/lib/liblept.5.dylib /usr/local/lib
ln -s /opt/homebrew/Cellar/tesseract/5.3.0_1/lib/libtesseract.5.dylib /usr/local/lib
ln -s /opt/homebrew/Cellar/libtiff/4.4.0_1/lib/libtiff.5.dylib /usr/local/lib
现在通常您可以运行脚本了。
包含地址应为：
/opt/homebrew/Cellar/leptonica/1.82.0/include/opt/homebrew/Cellar/leptonica/1.82.0/include/leptonica我在运行 C++ 代码时遇到了同样的问题，我包含了正确的路径，并且程序找到了
leptonics/allheader.h首先
brew install tesseractpip install tesserocr在 pip 23.1.1、Python 3.10.11 上。另外，我使用的是较旧的 MacBook，而不是 M1，但我遇到了与 OP 相同的错误。
我在这里找到了一个修复程序，它适用于 golang，但也可能适用于 python。 https://github.com/otiai10/gosseract/issues/234
使用
brew install tesseractexport LIBRARY_PATH="/opt/homebrew/lib"
export CPATH="/opt/homebrew/include"
