Rebuild uwsgi with pcre support
PcreUwsgiPcre Problem Overview
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.
Pcre Solutions
Solution 1 - Pcre
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 - Pcre
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.
Solution 3 - Pcre
pip uninstall uwsgi
sudo apt-get install libpcre3 libpcre3-dev
pip install uwsgi
I solved it with the above commands.
Solution 4 - Pcre
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
Solution 5 - Pcre
Did you try:
pip install uwsgi -I
The -I flag will force it to reinstall
Solution 6 - Pcre
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
Solution 7 - Pcre
If you have tried all above but it is still have the same error and with the below ones, please check your command parameters, particular the --http-socket /path/to/your.sock. That is the path = '/path/to' must be existed
thunder lock: disabled (you can enable it with --thunder-lock)
bind(): No such file or directory [core/socket.c line 230]
Solution 8 - Pcre
Maybe you can check the uid & gid, I got this ERROR when I set them wrong.
