Rebuild uwsgi with pcre support

When running uwsgi I got the following message:

!!! no internal routing support, rebuild with pcre support !!!

I already have installed pcre (I think) with the following command:

sudo apt-get install libpcre3 libpcre3-dev

Why am I still getting this message even after I have installed the pcre package, if I need to reinstall uwsgi and activate pcre, how do I do it?

Also, does internal routing matter?

I assume it does or else the makers of uwsgi wouldn't have made the message come up. I am running Ubuntu 12.04 LTS.

Solution 1:

pip install uwsgi -I

Won't recompile the uwsgi binary, it just reinstalls the python egg. You need to rebuild the uwsgi binary with the pcre libraries.

sudo apt-get install libpcre3 libpcre3-dev

I think the easiest way is just to uninstall uwsgi and then run the pip installer again.

pip uninstall uwsgi
sudo apt-get remove uwsgi

then

pip install uwsgi

you should see pip run the setup.py script and a bunch of compiler messages. The last message should show you something like this:

################# uWSGI configuration #################

pcre = True
kernel = Linux
malloc = libc
execinfo = False
ifaddrs = True
ssl = True
zlib = True
locking = pthread_mutex
plugin_dir = .
timer = timerfd
yaml = embedded
json = False
filemonitor = inotify
routing = True
debug = False
capabilities = False
xml = libxml2
event = epoll

############## end of uWSGI configuration #############

notice how pcre = true now

Solution 2:

pip install uwsgi -I --no-cache-dir

It reinstalls (-I) as @leech said, but ignores the compiled cache (--no-cache-dir) and recompiles the thing with the new libs.
