具有pcre支持的uWSGI

我安装了带有pcre支持的uWSGI（在Heroku上） 我得到了这个信息：

################# 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 #############

但是，当我使用uwsgi--pcre-jit启动它时

我明白了：

pcre jit已禁用。为什么uwsgi不使用pcre？

pcre jit是pcre库中必须支持的优化。可能heroku（或您用于pcre的构建包）已经更改了DDAMN，这是几周前在常规python构建包和新的cedar堆栈中实现的。uwsgi内部路由不再工作。jit只是一种优化，uwsgi内部路由不需要它，任何pcre版本都适用于包含libpcre3（1:8.31-2ubuntu2）、libpcre3 dev（1:8.31-2ubuntu2）和libpcrecpp0（1:8.31-2ubuntu2）的itHeroku Cedar-14。它应该会起作用。（它正在工作…）你的意思是“pcre jit禁用”仅仅意味着只有jit优化被禁用？如何检查是否至少加载了一个pcre库？我确认：pcre正在工作。谢谢
