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`.

Accepted Answer

```
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
