php - 从 PHP 调用时 pip 包导入失败

Question

我尝试在共享网络服务器上运行 python 脚本。它在 SSH 中运行良好，例如:

./../python/bin/python cgi-bin/script.py

但是，当我希望它通过 PHP 运行时，python 脚本会一直运行，直到它导入 pip 包。

错误来自于导入已安装的 pip 包。

我试着搞弄权限，将所有文件和目录都设置为 755 和 chmod x我尝试手动全新安装 python 2.7(网络服务器默认运行 python 2.6，因此 python 调用“./../python/bin/python”，我无法安装 3.5 我遇到了很多错误和超时。)我没有 sudo 权限。

脚本.py

print "I will be displayed! yay it works\n"

# import the necessary packages
import numpy as np
import argparse
import cv2
import os

print "I won't be displayed, it does not work!\n"

运行python.php

<?php
$query='./../python/bin/python cgi-bin/script.py 2>&1';
$command=escapeshellcmd($query);
$output=shell_exec($command);
echo $output;

$last_line=system($query, $retval);
echo '</pre>
<hr />Last line of the output: ' . $last_line . '
<hr />Return value: ' . $retval;
?>

我希望从 python 脚本中显示两个打印件，但它只显示第一个打印件。导入已安装的 pip 包时出现问题。

用于安装 python 包的用户必须与执行 python 脚本的用户相同。这是执行脚本的“网络服务器用户”，我认为您与其他用户一起安装了软件包
