解决error while loading shared libraries: libicui18n.so.55: cannot open shared object file

编译报错：
dtools: error while loading shared libraries: libicui18n.so.55: cannot open shared object file: No such file or directory
ninja: build stopped: subcommand failed.

libicu55 was supported until Ubuntu 16.04 Xenial, but it is compatible with 18.04 Bionic as well.

Add the following repository and install the package

sudo add-apt-repository “deb http://security.ubuntu.com/ubuntu xenial-security main”
sudo apt-get update
sudo apt-get install libicu55
