PIP安裝tesseract-ocr：失敗，退出狀態2

Question

我一直試圖安裝Tesseract-ocr庫很長一段時間。閱讀許多與其他軟件包相關的問題並給出解決方案，但都沒有成功。

我認爲問題是關於我的Microsoft Visual Studio。有下面給出代碼中的錯誤：

錯誤：命令 'C：\ Program Files文件（x86）的\微軟的Visual Studio 10.0 \ VC \ BIN \ x86_amd64 \ cl.exe時' 失敗，退出狀態2

我卸載，重新安裝，更新和嘗試了很多東西，但仍然沒有工作:(

由於現在已經

考慮使用pytesseract，爲我工作在Python的3.6：PIP安裝pytesseract

如果遇到運行上面的命令直接安裝它的問題，試試這個鏈接： http://www.lfd.uci.edu/~gohlke/pythonlibs/

使用「查找」工具來查找pytesseract和在目錄中的下載，按住shift鍵並點擊右鍵，你會得到一個選項，有打開命令窗口並運行：

PIP安裝「文件名」

你也可以嘗試下載的Tesseract-OCR從上面的鏈接就像我剛纔解釋執行安裝離線。 從來沒有完全弄清楚爲什麼，但一些安裝失敗時工作下載。希望有所幫助。
