我已经在 mac (ventura) 上安装了 tesseract。当我在终端中运行它时，它工作正常。当我使用位于的 apache2 服务器运行 html php 代码时
'/usr/local/' '/private/'当我尝试在 xampp 上运行 tesseract 时出现问题！
在 mac 上我首先收到错误：
Error! The command "tesseract" was not found. Make sure you have Tesseract OCR installed on your system: https://github.com/tesseract-ocr/tesseract The current $PATH is /usr/bin:/bin:/usr/sbin:/sbin
如果我更改执行路径，我会收到以下错误：
[01-Mar-2024 14:33:41 Europe/Berlin] PHP Fatal error: Uncaught thiagoalessio\TesseractOCR\UnsuccessfulCommandException: Error! The command did not produce any output.
Generated command:

Returned message:

我的猜测是，它与 (1) php xampp 执行命令有关，因为我也尝试过在 php 中执行 tesseract 命令，但没有任何效果。或者，（2）环境路径 - 我不确定它是如何工作的，所以我无法正确解释它。
我使用的代码是：
<?php
$fileRead = '';
use thiagoalessio\TesseractOCR\TesseractOCR;
require 'vendor/autoload.php';
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
if (isset($_POST['submit'])) {
$file_name = $_FILES['file']['name'];
$tmp_file = $_FILES['file']['tmp_name'];
if (!session_id()) {
session_start();
$unq = session_id();
}
$file_name = uniqid() . '_' . time() . '_' . str_replace(array('!', "@", '#', '$', '%', '^', '&', ' ', '*', '(', ')', ':', ';', ',', '?', '/' . '\\', '~', '`', '-'), '_', strtolower($file_name));
if (move_uploaded_file($tmp_file, 'uploads/' . $file_name)) {
try {
$fileRead = (new TesseractOCR('uploads/' . $file_name))
->setLanguage('eng')
->run();
} catch (Exception $e) {
echo $e->getMessage();
}
} else {
echo "<p class='alert alert-danger'>File failed to upload.</p>";
}
}
}
?>

我不熟悉 php，但是
Error! The command "tesseract" was not foundPATH看看提供Tesseract功能的php库的配置，是否可以定义Tesseract的绝对路径。或者调整负责的环境/php 变量，以便您可以在脚本中使用 tesseract 安装。
