在64位Mac OSX上的64位python解释器上构建“orjson”时，requirement.txt安装失败

Question

正在为项目运行requirements.txt安装（Fast API）。以下面的错误结束。我试着从https://github.com/rust-lang/rust/issues/61925开始接近 我使用仍然面临错误的rustup override set nightly将rust设置为“夜间”

请告知！ 谢谢大家!

Answer 1

这个错误似乎与使用“Z”选项的durimin命令有关，该选项仅适用于夜间编译器。您可以先尝试安装

安装夜间工具链：

rustup install nightly

切换到夜间工具链作为默认工具链：

rustup default nightly

然后尝试安装这些依赖项。希望这能奏效
