問題描述：
mac安裝telnet出現問題。
brew install telnet
Failed to connect to 127.0.0.1 port 10010: Connection refused
MacBook-Pro:homebrew-core user$ brew install telnet
==> Downloading https://homebrew.bintray.com/bottles/telnet-60.mojave.bottle.tar.gz
curl: (7) Failed to connect to 127.0.0.1 port 10010: Connection refused
Error: Failed to download resource "telnet"
Download failed: https://homebrew.bintray.com/bottles/telnet-60.mojave.bottle.tar.gz
Warning: Bottle installation failed: building from source.
telnet: A full installation of Xcode.app is required to compile
this software. Installing just the Command Line Tools is not sufficient.
Xcode can be installed from the App Store.
Error: An unsatisfied requirement failed this build.
MacBook-Pro:homebrew-core lijianglong$ source ~/.bash_profile unproxy
MacBook-Pro:homebrew-core lijianglong$ brew install telnet

查看代理：
env|grep -i proxy
爲：
ALL_PROXY=socks5://127.0.0.1:10010
故：使用代理導致訪問失敗
解決：
export http_proxy=""
export https_proxy=""
export HTTP_PROXY=""
export ALL_PROXY=""
可以直接在~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc中添加一個函數進去。

# 開啓代理
proxy () {
export https_proxy=http://127.0.0.1:10086
export http_proxy=http://127.0.0.1:10001
export ALL_PROXY=socks5://127.0.0.1:10010
echo "Proxy on"
}
# 關閉代理
unproxy () {
export https_proxy=""
export http_proxy=""
export ALL_PROXY=""
echo "Proxy off"
}
|
之後執行source ~/.bash_profile(對應自己的startup files文件)。
需要開啓代理的時候就執行proxy，關閉就執行unproxy。
再次執行安裝telnet成功！
