はじめに
つまづいたのでメモ
Vesrion
go version go1.14.4 windows/386
何が起きたか
プロキシ環境下で go getするとうまくいかない。
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
Git の設定やVisualStudioCodeの設定を見直してもうまくいかない。
どうしたか
コマンドプロンプトを開いて以下の環境変数を宣言
SET http_proxy=プロキシURL:ポート番号
SET https_proxy=%http_proxy%
そして、go get
$ go get -v github.com/labstack/echo
