在python3中安裝指紋模塊時出錯

Question

我正在嘗試在python中安裝指紋模塊，但出現此錯誤。

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

我嘗試了命令

pip install fingerprints 

錯誤的總描述如下所示。

請幫我解決這個問題。

Answer 1

我昨天在嘗試安裝不同於github的軟件包時遇到了同樣的錯誤。 我通過下載zip文件並手動安裝它解決了問題，沒有出現任何問題。

在此之前，您可能需要嘗試'pip3 install git + <copy_GitHub_web_URL_here>'。 您可以從他們的GitHub頁面上獲得它： https : //github.com/alephdata/fingerprints 。

在過去的幾個月中，我一直遇到很多egg_info錯誤，因此其他建議（這些建議從未用過，但對某些人來說可能是值得的）：更新pip和setuptools，並嘗試使用pip3 install或sudo pip3 install而不只是pip install。

我希望這會有所幫助。 如果不是這樣，我希望對這個問題有更多了解的人可以提供幫助，因為我對此還很陌生。
