Question

我需要上传图片并以文本格式提取该图片中的文字。该图片将是我将从移动应用程序获得的名片。我用节点js做到了。我尝试使用ocr npm但我在安装ocr作为依赖时遇到错误，即

$ npm install ocr
> ref@1.3.5 install E:\node_modules\ref
> node-gyp rebuild


E:\node_modules\ref>if not defined npm_config_node_gyp (node 
"C:\Users\Hello\AppData\Roaming\npm\node_modules\npm\node_modules\npm-
lifecycle\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild 
)  else (node 
"C:\Users\Hello\AppData\Roaming\npm\node_modules\npm\node_modules\node-
gyp\bin\node-gyp.js" rebuild )

有没有办法解决这个问题或我可以用来从图像中读取文本的任何其他节点模块？

Answer 1

在Ubuntu中安装ocr时遇到相同的错误。据我说，这是操作系统特定的错误。当我尝试使用“ npm i ocr”在MAC OS中安装ocr时，它已成功安装。所以您可以尝试一下。
