安装 tesseract 时遇到问题

Question

安装 tesseract 时遇到问题，查看了 google 和 Whosebug。还是一头雾水。

这是运行时 CMD 的结果：npm install -tesseract

C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app>npm install tesseract

> tesseract@0.0.3 install C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\node_modules\tesseract
> node-gyp rebuild

有人可以指导我吗？我已通过管理员将 Python 安装到 c 驱动器和程序文件 (64) 中。节点模块不在 python 文件中。

您打算安装库还是 Python 绑定？

图书馆installation on Windows:

Installer for Windows for Tesseract 3.05 and Tesseract 4 are available from Tesseract at UB Mannheim. These include the training tools. Both 32-bit and 64-bit installers are available.

An installer for the OLD version 3.02 is available for Windows from our download page. This includes the English training data. If you want to use another language, download the appropriate training data, unpack it using 7-zip, and copy the .traineddata file into the 'tessdata' directory, probably C:\Program Files\Tesseract-OCR\tessdata.

而 tesseract bindings for Python 可以通过 pip 从命令行安装：

pip install pytesseract

npm 不是 Python 包管理器，所以 tesseract 安装确实失败了。
