WARNING: The Python installation you are using does not appear to have
been installed with a shared library, or in the case of MacOS X, as a
framework. Where these are not present, the compilation of mod_wsgi may
fail, or if it does succeed, will result in extra memory being used by
all processes at run time as a result of the static library needing to
be loaded in its entirety to every process. It is highly recommended
that you reinstall the Python installation being used from source code,
supplying the '--enable-shared' option to the 'configure' script when
configuring the source code prior to building and installing it.

答案 0 :(得分:2)
如mod_wsgi文档中所述,您的问题是缺少适用于Python的共享库。
如果您自己从源代码安装Python,还请阅读:
忽略有关docker的内容。出现同样的问题。您必须谨慎选择配置选项。
答案 1 :(得分:1)
如安装警告所示,您正在尝试将mod-wsgi
安装到不提供共享库的python中。
从源代码编译python
时,请添加--enable-shared
标志,以使其产生一个libpython#.#.so
共享对象,可以对其进行链接

感谢@Graham Dumpleton分享了有用的链接。
我从仅--enable-shared的源软件包中安装了python,因此出现错误“ python:加载共享库时出错:libpython3.6m.so.1.0:无法打开共享库文件:没有这样的文件或目录”尝试通过pip3安装软件包时
按照以下步骤进行操作。
./configure --prefix /usr/local --enable-shared LDFLAGS="-Wl,-rpath,/usr/local/lib"
make
make install
现在pip3 install mod-wsgi可以正常工作。
