python-3.x - 无法为 Tesseract v4 安装 tesserocr - MacOS

Question

我正在尝试 pip 安装 tesserocr但遇到以下错误。我尝试了几种不同的方法来安装其文档中建议的方法，但都无济于事。

此时我确定问题与此软件包无关(因为我的 friend 将它安装在他的 Mac 上没有问题，我也安装在没有问题的 Ubuntu VM 上)。错误似乎是 c++ 库，因为它找不到 header 或 Tesseract-OCR 的源代码(？)，但是在它成功找到错误行之前。

我也安装了 pytesseract 没有问题。

我希望这里有人可以帮助调试导致此问题的原因。

我的 tesseract(通过 brew 安装)版本是:tesseract 4.0.0
leptonica-1.76.0
libjpeg 9c:libpng 1.6.35:libtiff 4.0.9:zlib 1.2.11


谢谢，让我知道您可能需要的其他信息。

我在我的 mac 上遇到了同样的问题，

您应该尝试使用 conda 安装软件包:

conda 安装-c mcs07 tesserocr
