安裝 intl 擴(kuò)展報(bào)錯(cuò)：
configure: error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works
CentOS解決方案：yum -y install libicu-devel
接著繼續(xù)安裝
mac解決方案：
brew install icu4c(僅僅安裝這個(gè)，configure的時(shí)候依然報(bào)同樣的錯(cuò)誤)
brew link icu4c --force
make的時(shí)候報(bào)錯(cuò)

···
make: *** [intl_convertcpp.lo] Error 1
解決方案：
打開 /Applications/NMP/src/php-7.1.3/ext/intl/Makefile
搜索 CXXFLAGS = -g -O2 行并添加 -std = c ++ 11
CXX = g++
CXXFLAGS = -g -O2 -std=c++11
CXXFLAGS_CLEAN = $(CXXFLAGS)
重新make，如果修改文件之后，make clean 剛才修改的會(huì)被重置
