錯誤：HelloWorld 尚未部署到檢測到的網路（網路/工件不匹配）

我正在按照此連結中的步驟創建一個松露項目。我使用 ganache-cli 作為乙太坊客戶端。

   rajkumar@rajkumar: Ethereum$ mkdir helloworld
   rajkumar@rajkumar: Ethereum$ cd helloworld/
   rajkumar@rajkumar: helloworld$ sudo truffle init

   ✔ Preparing to download
   ✔ Downloading
   ✔ Cleaning up temporary files
   ✔ Setting up box

   Unbox successful. Sweet!

   Commands:

   Compile:        truffle compile
   Migrate:        truffle migrate
   Test contracts: truffle test

   rajkumar@rajkumar: helloworld$ truffle create contract HelloWorld
   rajkumar@rajkumar: helloworld$ sudo truffle create contract HelloWorld

然後我用這裡的智能合約更新了智能合約。

   rajkumar@rajkumar: helloworld$ sudo truffle create migration HelloWorld
   rajkumar@rajkumar: helloworld$ sudo truffle migrate --network development
   [sudo] password for rajkumar:

   truffle(development)>

為什麼我會遇到錯誤？我怎樣才能解決這個問題？

在 migrate 文件夾中的 HelloWorld 遷移文件中，您應該打開它並通過教程添加以下內容：

var HelloWorld = artifacts.require('HelloWorld');

module.exports = function(deployer) {
 // Use deployer to state migration tasks.
 deployer.deploy(HelloWorld);
};

您應該閱讀松露文件以獲取更多詳細資訊：https ://www.trufflesuite.com/docs/truffle/getting-started/running-migrations 。

看起來您已部署到development網路，但truffle console使用預設網路執行，因此假設它們是不同的。

您應該在同一網路上部署和使用控制台。

truffle migrate --network development

truffle console --network development

順便說一句，您不必使用 sudo。您可能需要考慮在本地安裝軟體包。

我只ganache-cli安裝了全域。
