在python 3.x中安装Pyicu

Question

我的系统是Windows 10 x64

现在我想安装pyicu但我遇到了这样的问题

Collecting pyicu

使用缓存PyICU-1.9.7.ta​​r.gz从命令python setup.py egg_info完成输出:Traceback(最近一次调用最后一次):文件"C:\ Users\ANHVU\AppData\Local\Temp\pip-build-v5fb9ri4\pyicu\setup.py",第12行,在ICU_VERSION = os.environ ['ICU_VERSION']文件"C:\ Users\ANHVU\AppData\Local\Programs\Python\Python35\lib\os.py",第725行,在getitem中 从None KeyError引发KeyError(key):'ICU_VERSION'

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_amd64.whl

然后以管理员身份打开Windows Powershell控制台,cd到您放置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
