macos - tesseract 安装 mac os

Question

我正在尝试使用 homeBrew 在我的 Mac 上安装 tesseract。当我尝试安装时，一切似乎都很好，但我收到以下错误/消息:

Warning: Could not link leptonica. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link leptonica'

当我尝试运行 tesseract 函数时，出现以下错误:

Tesseract Open Source OCR Engine v3.02.02 with Leptonica
Error in pixReadStreamPng: function not present
Error in pixReadStream: png: no pix returned
Error in pixRead: pix not read
Unsupported image type.

我安装了 image magick，我用来安装 tesseract 的命令是:

brew install tesseract

谁能告诉我我能做些什么来让tesseract工作？谢谢!

编辑
当我运行 brew link leptonica 时，出现以下错误:

Could not symlink file: /usr/local/Cellar/leptonica/1.69/bin/yuvtest
Target /usr/local/bin/yuvtest already exists. You may need to delete it.

Answer 1

现在，截至 2019 年 9 月，不再有任何可选的安装标志可用

brew options tesseract

一无所获。但，

brew info tesseract

产生以下关键信息:

This formula contains only the "eng", "osd", and "snum" language data files.
If you need all the other supported languages, `brew install tesseract-lang`.

因此，要安装所有语言，您现在需要安装一个名为 tesseract-lang 的单独库。 .

更新安装:

brew install tesseract
brew install tesseract-lang

希望这可以帮助。

旧的，以防万一这很有用:

现在，截至 2019 年 1 月，只要您先安装了 xquartz，Tesseract 就可以通过 Homebrew 软件正常安装， brew cask install xquartz .然后您可以执行以下操作: brew install tesseract --with-all-languages --with-serial-num-pack --with-training-tools
