I am trying to get mod_wsgi working with Apache 2.4.6 on RHEL. I have
access to the sudo command but not root.
The net-net: No matter what I have tried, I can not get mod_wsgi to see the
associated python modules for the virtual environment that it was
configured for using Anaconda 3.
The good news: According to the Apache error log files, mod_wsgi has loaded
successfully.
The bad news is that I receive numerous messages: Fatal Python error:
Py_Initialize: Unable to get the locale encoding ModuleNotFoundError: No
module named 'encodings'
I've spent two days trying what I believe is every combination of
configurations I've seen from the various posts I've read on virtual
environments, all to no avail.
I even pasting the output of mod_wsgi module-config into the httpd.conf
file. The LoadModule statement fails with a permissions error even though
all of the files in the entire directory have been set to 777.
The only way I have been able to get the mod_wsgi module to load has been
to:
1. Build mod_wsgi from source in the virtual environment of my application
2. Use the make install command to load the module into the apache modules
directory
3. Copy the libpython3.6m.so.1.0 directly into the /usr/lib64 directory
(allows mod_wsgi.so to see it).
But still, I get the ModuleNotFoundError: No module named 'encodings'
message
I'd really appreciate some help. Here's the state of my configuration:

import site
# Remember original sys.path.
prev_sys_path = list(sys.path)
# Add each new site-packages directory.
for directory in ALLDIRS:
site.addsitedir(directory)
# Reorder sys.path so new directories at the front.
new_sys_path = []
for item in list(sys.path):
if item not in prev_sys_path:
new_sys_path.append(item)
sys.path.remove(item)
sys.path[:0] = new_sys_path
def application(environ, start_response):
ex = sys.executable
status = '200 OK'
output = "Executable: {} ".format(ex)
response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]
Many, many thanks for any help this community can provide!!
