Rust更换Crates源

Rust编译时遇到如下问题:

Downloading futures v0.1.19 warning: spurious network error (2 tries remaining): [28] Timeout was reached (Operation timed out after 30857 milliseconds with 0 out of 0 bytes received) error: unable to get packages from source Caused by: [35] SSL connect error (OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to static.crates.io:443 )

解决办法:更换Crates源

Rust开发时有时使用官方的源太慢,可以考虑更换使用国内中科大的源。更换方法如下:

在 $HOME/.cargo/config 中添加如下内容:

[source.crates-io] replace-with = 'ustc' [source.ustc] registry = "git://mirrors.ustc.edu.cn/crates.io-index"

如果所处的环境中不允许使用 git 协议,可以把上述地址改为:

registry = "https://mirrors.ustc.edu.cn/crates.io-index"

为什么这么配置可以参考The Cargo Book/Source Replacement.
