嘗試在apache服務器上運行mod_wsgi時出錯

Question

我在/ var / www里面有一個Flask Project結構目錄：

item-catalog-fullstacknd\
    itemCatalogApp.wsgi
    itemCatalogApp\
        __init__.py

這是上面的WSGI文件：

import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/item-catalog-fullstacknd/")
from itemCatalogApp import app as application
application.secret_key = 'Add your secret key' 

這是/etc/apache2/sites-enabled/000-default.conf

WSGIPythonPath /var/www/item-catalog-fullstacknd/itemCatalogApp/
<VirtualHost *:80>
    WSGIScriptAlias / /var/www/item-catalog-fullstacknd/itemCatalogApp.wsgi

            <Directory /var/www/item-catalog-fullstacknd/itemCatalogApp>
                    Order allow,deny
                    Allow from all
            </Directory>

            Alias /static /var/www/item-catalog-fullstacknd/itemCatalogApp/static

            <Directory /var/www/item-catalog-fullstacknd/itemCatalogApp/static/>
                    Order allow,deny
                    Allow from all
            </Directory>

</VirtualHost>

我收到以下錯誤：

mod_wsgi (pid=17586): Exception occurred processing WSGI script '/var/www/item-catalog-fullstacknd/itemCatalogApp.wsgi'.
 Traceback (most recent call last):
   File "/var/www/item-catalog-fullstacknd/itemCatalogApp.wsgi", line 6, in <module>
     from itemCatalogApp import app as application
   File "/var/www/item-catalog-fullstacknd/itemCatalogApp/__init__.py", line 3, in <module>
     from flask import Flask, jsonify, render_template, request
 ImportError: No module named flask

我已經pip install了requirements.txt文件中包含的所有模塊。 我不知道該怎么辦了。

您可能已經為其他python可執行文件安裝了模塊，而不是mod_wsgi默認使用的模塊。 要檢查，添加到您的WSGI文件的beggining：

import sys
print(sys.executable)

然后，打開外殼，運行python並在其中鍵入相同的代碼。 如果path不同，則應指定WSGIPythonHome指向所需的python可執行文件 。
