Python 在Amazon EC2实例中设置Flask应用程序，获取ImportError:没有名为Flask的模块

我在Amazon EC2服务器上部署Flask应用时遇到问题

我遵循了一个教程，然后开始学习

当我运行我的服务器时，在执行

sudoapachect1重新启动后

导航到我的ec2站点时，我得到一个500内部错误。检查日志时，我发现以下错误

[Tue Jun 20 19:10:48.429468 2017] [wsgi:error] ImportError: No module named flask, referer: http://ec2-<MY-EC2-URL>.amazonaws.com/

我认为这可能是找不到Python路径的问题。因此，我在apache的配置文件中添加了

python路径=/usr/lib/python2.7

000 default.conf

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    WSGIDaemonProcess leu threads=5 python-path=/usr/lib/python2.7
    WSGIScriptAlias / /var/www/html/leu/app.wsgi

    <Directory leu>
        WSGIProcessGroup leu
        WSGIApplicationGroup %{GLOBAL}
        Order deny,allow
        Allow from all
    </Directory>

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

有什么帮助吗

编辑：

还尝试将上面我的Apache配置文件中Python的路径更改为

/usr/local/lib/python2.7

，但仍然没有成功

使用sudo-H安装模块

如果仍然存在，那么您必须更改配置以使用python 2.7而不是python 3

我知道我已经太迟了……希望这对正在挣扎的人有用

ServerName your EC2 instance

您必须提到您的EC2实例

我认为第一步是确保您可以在本地访问服务器。本地主机：在EC2上。然后在尝试从浏览器访问EC2实例时，检查该实例的传入端口设置是否打开

import sys
sys.path.insert(0, 'var/www/html/leu')

from app import app as application

ServerName your EC2 instance
