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

例如，您的 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_amd64.whl

然后以管理员身份打开Windows Powershell控制台，cd到你放置whl文件的目录，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
