Question

我有一个python脚本被称为php的shell_exec命令。一切都很好，除了它通过shell_exec调用时无法导入NLTK语料库。然而，每当我直接从shell调用它时，执行完全相同的命令没有问题。我正在使用Debian 8。

这是我的php代码：

$cmd = "/usr/bin/python /var/www/include/sCrape.py -u '$my_url' ";
$response = shell_exec($cmd);
$response = json_decode($response, true);

当从根目录直接调用（没有sudo）时，此命令很有效：

/usr/bin/python /var/www/include/sCrape.py -u '$my_url'

我得到的python脚本的错误消息（仅当我从PHP的shell_exec调用时）是：

Traceback (most recent call last):

    line 221, in main() File "/var/www/include/sCrape.py",
