錯誤！提供的建構子參數無效。請驗證它們是否為 ABI 編碼格式
更新：所以我的程式碼中的這兩行似乎是導致問題的原因，刪除它們可以讓一切正常工作，但我仍然需要包含它們，所以如果有人能弄清楚他們為什麼會破壞這將有所幫助。
require(delay_ >= MINIMUM_DELAY, "Timelock::constructor: Delay must exceed minimum delay."); require(delay_ <= MAXIMUM_DELAY, "Timelock::constructor: Delay must not exceed maximum delay.");這是我試圖部署到 ropsten 的契約

所以問題出在require語句上
似乎更改 require 語句中的註釋使它起作用。可能與我的編譯器未處理該語句和“Timelock::constructor: Delay must超過 minimum delay”有關。正確，從而提供不正確的字節碼。
作品
require(delay_ >= MINIMUM_DELAY, "Not over minimum"); require(delay_ <= MAXIMUM_DELAY, "Not over maximum");不工作
require(delay_ >= MINIMUM_DELAY, "Timelock::constructor: Delay must exceed minimum delay."); require(delay_ <= MAXIMUM_DELAY, "Timelock::constructor: Delay must not exceed maximum delay.");
