vendor/ 與第 3 方依賴項的子目錄關係

在-go-ethereum客戶端目錄中，我執行了find . -name \*.md -print查找README.md文件的命令。輸出如下：

基於此，看起來所有“第 3 方”依賴項都位於vendor/目錄中。是這樣嗎？為什麼這個目錄被稱為vendor？

是，對的。

為什麼這個目錄被稱為供應商？

這是 Go 中的約定，在 golang 1.6 中引入（在 1.5 中進行實驗）。

請參閱官方文件，此處：https ://golang.org/cmd/go/#hdr-Vendor_Directories

簡而言之：

Go 1.6 支持使用外部依賴項的本地副本來滿足這些依賴項的導入，通常稱為供應商。

名為“vendor”的目錄下的程式碼只能通過以“vendor”的父級為根的目錄樹中的程式碼導入，並且只能使用省略前綴直到並包括 vendor 元素的導入路徑。
