AMH安装intl拓展失败？

Question

AMH安装intl拓展失败
LNMP环境intl已安装但是拓展安装失败
最后一行报错：
configure: error: Package requirements (icu-uc >= 50.1 icu-io icu-i18n) were not met:

No package 'icu-uc' found
No package 'icu-io' found
No package 'icu-i18n' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables ICU_CFLAGS
and ICU_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
make: * No targets specified and no makefile found. Stop.
make: * No rule to make target `install'. Stop.
mv: cannot stat '/usr/local/php-8.1/lib/php/extensions/no-debug-non-zts-20210902/intl.so': No such file or directory

libicu这个包没安装成功，确认系统软件源是否还可用，centos8、7系统的生命周期已经结束，如果用的以上系统，要更换系统软件源，也可以手动安装：
yum install libicu-devel

debian系的系统，
apt install libicu-dev

做测试看。
