在python3中安装指纹模块时出错

Question

我正在尝试在python中安装指纹模块，但出现此错误。

RuntimeError:
Please set the ICU_VERSION environment variable to the version of
ICU you have installed.

我尝试了命令

pip install fingerprints 

错误的总描述如下所示。

请帮我解决这个问题。

Answer 1

我昨天在尝试安装不同于github的软件包时遇到了同样的错误。 我通过下载zip文件并手动安装它解决了问题，没有出现任何问题。

在此之前，您可能需要尝试'pip3 install git + <copy_GitHub_web_URL_here>'。 您可以从他们的GitHub页面上获得它： https : //github.com/alephdata/fingerprints 。

在过去的几个月中，我一直遇到很多egg_info错误，因此其他建议（这些建议从未用过，但对某些人来说可能是值得的）：更新pip和setuptools，并尝试使用pip3 install或sudo pip3 install而不只是pip install。

我希望这会有所帮助。 如果不是这样，我希望对这个问题有更多了解的人可以提供帮助，因为我对此还很陌生。
