tesseract安装mac os [英] tesseract install mac os

问题描述

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，但是出现以下错误/消息:

I am trying to install tesseract on my mac using homeBrew. When I try installing, everything seems to be good but I get the following error/message:

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:

When I try running a tesseract function, I get the following error:

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.

我已经安装了image magick，并且我用来安装tesseract的命令是:

I have image magick installed and the command I used to install tesseract was:

brew install tesseract

有人可以告诉我如何使tesseract工作吗?谢谢！

Can anyone please tell me what I can do to get tesseract working? Thank you!

编辑 当我运行brew link leptonica时，出现以下错误:

EDIT When I run brew link leptonica, I get the following error:

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.

推荐答案

现在，截至2019年9月，不再提供任何可选的安装标志

Now, as of September 2019, there are no longer any optional install flags available

brew options tesseract

什么也没产生.但是

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的单独的库.

Therefore, to get all of the languages installed, you need to now install a separate library called tesseract-lang.

更新的安装:

brew install tesseract
brew install tesseract-lang

希望这会有所帮助.

旧，以防万一:

现在，从2019年1月开始，只要您首先安装了xquartz，，Tesseract就可以通过自制软件正常安装了.然后，您可以执行以下操作:brew install tesseract --with-all-languages --with-serial-num-pack --with-training-tools

Now, as of January 2019, Tesseract installs fine via homebrew, as long as you have xquartz installed first, brew cask install xquartz. Then you can do the following: brew install tesseract --with-all-languages --with-serial-num-pack --with-training-tools
