在python3.6.2最近安装的包中安装PyICU时出错

Question

所以，刚刚安装了最新的3.6.2版本的python版本和更新的pip和setuptools，所以我开始安装PyICU，在没有安装错误的情况下，我在互联网上导航时没有找到相同的错误，我在1.9.5中发现了一些类似的错误，但是看起来不一样。有人有线索吗？

python安装-m PyICU

如果在Linux上发生错误，则应该安装ibicu-dev (在Debian上)：

sudo apt-get install libicu-dev

我在一个新的Ubuntu安装中遇到了这个问题，并且能够通过安装pkg-config来修复它，这样安装就可以知道安装了哪个icu版本：

sudo apt install pkg-config
