if a proxy or similar is necessary `net.git-fetch-with-cli` may help here

我编译的时候出现了上面的错误 我正在使用 Ubuntu 20.04.2.0,基板 3.0.0
我的 rust 版本:
gh@ubuntu:~/substrate-node-template$ rustup show
Default host: x86_64-unkNown-linux-gnu
rustup home: /home/gh/.rustup
installed toolchains
--------------------
stable-x86_64-unkNown-linux-gnu (default)

active toolchain
----------------
stable-x86_64-unkNown-linux-gnu (default)
rustc 1.50.0 (cb75ad5db 2021-02-10)
我尝试在“货物构建 - 放松”_ HTTP_ Multiplexing = false “之前添加“货物”并执行。 但它不起作用。
解决方法
这不是一个基底问题。
尝试使用 VPN。或者使用镜像源。
