Python 无法导入 ssl 模块

Question

在 ubuntu-16.04 上安装了 xampp。 XAMPP根安装位置：/opt/lampp

Python 2.7.12 姜戈 1.11 XAMPP 5.6.30

wsgi.py 设置： ```蟒蛇

import os
import sys
import site

site.addsitedir('/opt/lampp/htdocs/dpcm/dpcm/lib/python2.7/site-packages')

sys.path.insert(0, '/opt/lampp/htdocs/dpcm')
sys.path.insert(1, '/opt/lampp/htdocs/dpcm/dpcm1')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "dpcm1.settings")
os.environ.setdefault("PYTHON_EGG_CACHE", "/opt/lampp/htdocs/dpcm/.python-eggs")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

# if import ssl module, it will occur an error.
import ssl

```

/opt/lampp/apache2/conf/httpd.conf 内容：

Alias /bitnami/ "/opt/lampp/apache2/htdocs/"
Alias /bitnami "/opt/lampp/apache2/htdocs"

<Directory "/opt/lampp/apache2/htdocs">
    Options Indexes FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

WSGIScriptAlias /dpcm/ /opt/lampp/htdocs/dpcm/dpcm1/wsgi.py

#WSGIDaemonProcess /dpcm/ python-path=/opt/lampp/htdocs/dpcm:/opt/lampp/htdocs/dpcm/dpcm/lib/python2.7/site-packages
#WSGIProcessGroup /dpcm/

WSGIPythonPath /opt/lampp/htdocs/dpcm
WSGIPythonHome /opt/lampp/htdocs/dpcm/dpcm/
<Directory /opt/lampp/htdocs/dpcm/dpcm1>
    <Files wsgi.py>
        Order deny,allow
        Require all granted
    </Files>
</Directory>

Alias /static/ /opt/lampp/htdocs/dpcm/static/
<Directory /opt/lampp/htdocs/dpcm/static>
   Order allow,deny
   Allow from all
</Directory>

如果在非活动模式下导入ssl模块，则可以成功导入。 但是如果在wsgi.py或者其他django项目文件中添加'import ssl'，就会报错：

在正常情况下，它将.so链接到/usr/lib，但它在/opt/lampp/lib中找到， 所以我认为这是环境变量问题。 在 shell 脚本中添加以下代码：lampp

LD_LIBRARY_PATH='/usr/lib'
export LD_LIBRARY_PATH

和注释代码

# if test "$(osguess)" = "macosx"
# then
#     # Thanks to drosenbe! - oswald [3sep10]
#     if test -z $DYLD_LIBRARY_PATH
#     then
#   export DYLD_LIBRARY_PATH="$LIBRARY_PATH"
#     else
#   export DYLD_LIBRARY_PATH="$LIBRARY_PATH:$DYLD_LIBRARY_PATH"
#     fi
# else
#     # Thanks to drosenbe! - oswald [3sep10]
#     if test -z $LD_LIBRARY_PATH
#     then
#   export LD_LIBRARY_PATH="$LIBRARY_PATH"
#     else
#   export LD_LIBRARY_PATH="$LIBRARY_PATH:$LD_LIBRARY_PATH"
#     fi
# fi

这个没用，有没有人和我一样的问题？

Answer 1

您的 Python 发行版是针对与您的 Apache 发行版使用的不同的 SSL 库编译的。 Apache 加载的优先，导致 Python 稍后失败。

简而言之，您不能使用该 Apache 发行版，因为它将与任何嵌入语言的 Apache 模块不兼容，例如 Python、PHP、Perl 等，其中语言运行时使用系统 SSL 库。请改用系统 Apache 发行版。

Answer 2

请也检查一下，这可能会有所帮助。 Why use sys.path.append(path) instead of sys.path.insert(1, path)?

Answer 3

刚导入

site.addsitedir('/opt/lapmpp/htdocs/dpcm/dpcm/lib/python2.7/site-packages')

应该是 /opt/lampp 而不是 /opt/lapmpp？

请尝试此更改。
