Python 3.x 在python3中安装库bls lib时出错

我曾尝试安装

bls lib

库，但此错误不断出现，有人能帮我解决问题吗？我甚至尝试安装

petlib

库，因为我认为它可以解决问题，但我得到了一个几乎相似的错误

你看过张贴的说明了吗？是的。但是当我尝试使用

vcvarsx86_amd64.bat

命令时，它一直告诉我它无法识别command@ewong为了确定，我必须在哪个路径中运行

vcvvarsx86_amd64.bat

来配置Microsoft VS的路径变量？您是否阅读了发布的说明？是的。但是当我尝试使用

vcvarsx86_amd64.bat
