Python 安装web3[tester]时出错：为blake2b py构建控制盘失败

我正试图使用

pip install-U web3[tester]

安装web3测试仪，但总是出现此错误

Pip和setuptools都在其当前版本上

完全错误：

You have to install a nightly or dev version of Rust (do you have rust installed at all ?)

EDIT
You can install rust nightly on macOS with following commands in the shell:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup default nightly

stderr线程“main”在“Error:pyo3需要夜间或开发版本的Rust”时惊慌失措

您必须安装Rust的夜间版本或开发版本（是否安装了Rust？）

编辑
您可以在shell中使用以下命令在macOS上每晚安装rust：

curl--proto'=https'--tlsv1.2-sSfhttps://sh.rustup.rs |嘘
每晚都会生锈
>要了解更多信息，请使用--verbose再次运行该命令。按照程序的建议去做就行了。（并将输出添加到您的帖子中！）我确实更新了它：）
