我的系统是Windows 10 x64

现在我想安装pyicu，但是遇到了这样的问题

您可以从Unofficial Windows Binaries for Python Extension Packages下载相应的whl文件

例如，64位Windows和Python3.7版本的最新版本（截至2019年1月13日）是PyICU-2.2-cp37-cp37m-win-u amd64.whl

然后以管理员身份打开Windows Powershell控制台，cd到放置whl文件的目录，并执行以下命令：

python -m pip install .\PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl

或者（如果您已经安装了以前的PyICU版本）

python -m pip install -U .\PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl
