Rebuild uwsgi with pcre support

Question

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.

Answer 1

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.

Answer 2

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

Answer 3

pip uninstall uwsgi

sudo apt-get install libpcre3 libpcre3-dev

pip install uwsgi

I solved it with the above commands.

Answer 4

Completing @alanjds answer, following is the process to add pcre support to your already installed uWSGI.

sudo apt-get install libpcre3 libpcre3-dev
pip install uwsgi -I --no-cache-dir

You do not need to uninstall uWSGI

Answer 5

Did you try:

pip install uwsgi -I 

The -I flag will force it to reinstall

Answer 6

For those who want to fix this on amazon linux 2 or any red hat family distros

First, Uninstall the uwsgi package

pip uninstall uwsgi

Then, Install pcre and pcre-devel

yum install pcre pcre-devel

Then, Reinstall the uwsgi package

pip install uwsgi
