从图像中读取数据

Question

我必须上传一张图片并以文本格式获取图片中的文字。该图像将是我将从移动应用程序中获取的名片。我已经使用节点 js 完成了。我尝试使用 ocr npm，但在安装 ocr 作为依赖项时出现错误，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 )

有什么方法可以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吗？

Answer 1

我在 Ubuntu 中安装 ocr 时遇到了同样的错误。根据我的说法，这是 OS 特定错误。当我尝试使用 "npm i ocr" 在 MAC OS 中安装 ocr 时，它已成功安装。所以你可以试试这个。
