我有一些问题。

这个 php (uploads.php) 脚本执行 gif.py python 文件。

<?php


    $file_path = "uploads/";
    $auth_token = $_POST['auth_token'];
    mysql_connect('localhost',"login",'pass');
    mysql_set_charset("UTF-8");
    mysql_select_db("DB_name");

    $sql = "SELECT user_id FROM users WHERE auth_token='$auth_token'";
    $result = mysql_query($sql);

    if(mysql_fetch_array($result)['user_id']==0)
    {
        echo "fail auth_token ".$auth_token;
        exit;
    }

    $file_md5 = md5(time()+$auth_token+rand(0,1000));

    $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], "uploads/".$file_md5.".mp4")) {
        $aaa = exec("/usr/bin/python gif.py b9022c5c317cf2317ad3f537dcc1cfbe");
        echo $file_md5."   ".$aaa;
    } else{
        echo "fail ".$_FILES['uploaded_file']['size']." ".$_FILES['uploaded_file']['tmp_name']." ".$file_path ;
    }
 ?>

gif.py 文件

#!/usr/bin/env python
from moviepy.editor import *
import sys

file_md5 = sys.argv[1]

anna_olaf = (VideoFileClip("uploads/" + file_md5+".mp4")
     .subclip(0,1)
         .resize(1))  

anna_olaf.write_gif('gifs/test.gif', fps=15)

我在上传文件夹中有b9022c5c317cf2317ad3f537dcc1cfbe.mp4 文件。我从 Linux 控制台调用 gif.py 或 uploads.php 文件的地方都可以（php uploads.php 或 pyhon gif.py），但是我从浏览器 python 文件调用 uploads.php 的地方不起作用，在 apache 日志中我发现

/usr/lib/python2.7/dist-packages/IPython/utils/path.py:296: UserWarning: IPython parent '/var/www' is not a writable location, using a temp directory.

    raise RuntimeError("Failed to create %s/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data"%h)
RuntimeError: Failed to create /var/www/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data

请帮助，在 2 行中的日志写入错误（来自 moviepy.editor import *）但为什么我在调用时没有错误（python gif.py）？

【问题讨论】：

错误报告的最后一行没有显示错误：RuntimeError: Failed to create /var/www/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data 我想说这可能是/var/www/ 文件夹的权限问题，不允许脚本根据需要创建文件。
oooo yeeeeeeeeeeeees !!!谢谢你的帮助。 :)
我会将评论作为答案发布，以防万一其他人遇到类似问题。

【解决方案1】：

正如 cmets 中所讨论的，问题显示在错误报告的最后一行，请参阅：

RuntimeError: Failed to create /var/www/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data

我想说这可能是/var/www/ 文件夹不允许脚本根据需要创建文件的权限问题。

要解决此问题，您应该更改文件夹的权限以使其可写或指定脚本应创建所需文件的不同目录。
