我确实得到了Flask& mod_wsgi成功使用Python3,并在短时间内感到高兴.

…直到我查看Apache的日志并意识到我遇到了这个问题：https://askubuntu.com/questions/569550/assertionerror-using-apache2-and-libapache2-mod-wsgi-py3-on-ubuntu-14-04-python

apt-get正在安装libapache2-mod-wsgi-py3的过时版本,这会导致Apache日志中的错误. (我应该报告这个,如果是这样的话？)

在链接中,工程师正在使用pip来安装更新的版本.

有趣的是,他似乎将其安装到虚拟Python3环境中. (这与使用系统pip3有什么不同吗？)

他也使用pip3 install mod_wsgi,但是pip3搜索mod_wsgi返回：

(编辑：不,他没有,他使用pip而不是pip3.这可能是对的吗？他的电线是否交叉？是不是要忽略他在py3venv中并简单地使用系统的py2安装的事实？但无论如何,这并没有解决混乱…)

mod_wsgi-metrics          - Metrics package for Apache/mod_wsgi.
cykooz.recipe.pastewsgi   - Buildout recipe to create paste.deploy entry points for mod_wsgi or uwsgi
mod_wsgi-httpd            - Installer for Apache httpd web server.
apachemiddleware          - Useful Python middleware for use with mod_wsgi deployments
tranchitella.recipe.wsgi  - Buildout recipe to create paste.deploy entry points for mod_wsgi
mod_wsgi                  - Installer for Apache/mod_wsgi.

那么什么是mod_wsgi-httpd？是否确定这不是我想要的？

最后,任何人都可以提供从源代码安装mod_wsgi的链接吗？

编辑：我不明白为什么工程师使用pip install mod_wsgi而不是pip3 ….当然那不可能是对的？但如果我使用pip3,我得到：

pi@PiDroplet:~$cd web/piFlask

----------------------------------------
Cleaning up...
Command python setup.py egg_info Failed with error code 1 in /home/pi/web/piFlask/venv3/build/mod-wsgi
Storing debug log for failure in /home/pi/.pip/pip.log

现在我尝试pip3安装mod_wsgi-httpd,编译大约需要五分钟：

(venv3)
pi@PiDroplet:~/web/piFlask$pip3 install mod_wsgi-httpd
Downloading/unpacking mod-wsgi-httpd
  Downloading mod_wsgi-httpd-2.4.12.5.tar.gz

    apr-1.5.2/config.layout
    apr-1.5.2/build.conf
    apr-1.5.2/emacs-mode
    :

所以现在我担心我的Py3 virtualenv中还有第二个Apache.

然而,这确实摆脱了错误; pip3 install mod_wsgi现在成功完成.

编辑：但是现在我完全不知道试图按照他的指示：我没有/etc/apache2/mods-available/wsgi_express.load,如果他建议制作它,那么一开始这似乎是随意的,其次是他建议放入的文本,即LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi-py34.cpython-34m.so – 我的系统上不存在此文件.

我有/etc/apache2/mods-available/wsgi.load

再次沉浸在技术中,有人会给我一条线吗？
