松露編譯和遷移不起作用

我的筆記型電腦上執行了一個 geth 節點。這是我用來啟動 geth 的命令。

geth --port 4321 --networkid 1234 --datadir=./dataDir  --rpc --rpcport 8543 --rpcaddr 127.0.0.1  --rpcapi "eth,net,web3,personal,miner"

geth 附加http://127.0.0.1:8543/

我的松露文件夾結構如下：

這是我的 truffle-config.js

**
* Use this file to configure your truffle project. It's seeded with some
* common settings for different networks and features like migrations,
* compilation and testing. Uncomment the ones you need or modify
* them to suit your project as necessary.
*
* More information about configuration can be found at:
*
* truffleframework.com/docs/advanced/configuration
*
* To deploy via Infura you'll need a wallet provider (like truffle-hdwallet-provider)
* to sign your transactions before they're sent to a remote public node. Infura API
* keys are available for free at: infura.io/register
*
* You'll also need a mnemonic - the twelve word phrase the wallet uses to generate
* public/private key pairs. If you're publishing your code to GitHub make sure you load this
* phrase from a file you've .gitignored so it doesn't accidentally become public.
*

// const HDWalletProvider = require('truffle-hdwallet-provider');
// const infuraKey = "fj4jll3k.....";
//
// const fs = require('fs');
// const mnemonic = fs.readFileSync(".secret").toString().trim();

module.exports = {
 /**
  * Networks define how you connect to your ethereum client and let you set the
  * defaults web3 uses to send transactions. If you don't specify one truffle
  * will spin up a development blockchain for you on port 9545 when you
  * run `develop` or `test`. You can ask a truffle command to use a specific
  * network from the command line, e.g
  *
  * $ truffle test --network <network-name>

  rpc: {
   host:"localhost",

},
 networks: {
   // Useful for testing. The `development` name is special - truffle uses it by default
   // if it's defined here and no other network is specified at the command line.
   // You should run a client (like ganache-cli, geth or parity) in a separate terminal
   // tab if you use this network and you must also set the `host`, `port` and `network_id`
   // options below to some value.

    development: {
      host: "127.0.0.1",     // Localhost (default: none)
      port: 8545,            // Standard Ethereum port (default: none)
     network_id: "*",

     gasPrice:2000000000,       // Any network (default: none)
    },

   // Another network with more advanced options...
   // advanced: {

     // websockets: true        // Enable EventEmitter interface for web3 (default: false)

   // Useful for deploying to a public network.
   // NB: It's important to wrap the provider as a function.

     // provider: () => new HDWalletProvider(mnemonic, `https://ropsten.infura.io/${infuraKey}`),

     // skipDryRun: true     // Skip dry run before migrations? (default: false for public nets )
   // },

   // Useful for private networks
   // private: {
     // provider: () => new HDWalletProvider(mnemonic, `https://network.io`),
     // network_id: 2111,   // This network is yours, in the cloud.

 // Set default mocha options here, use special reporters etc.
 mocha: {
   // timeout: 100000
 },

 // Configure your compilers
 compilers: {
   solc: {
      version: "0.6.0",    // Fetch exact version from solc-bin (default: truffle's version)
     // docker: true,        // Use "0.5.1" you've installed locally with docker (default: false)
     // settings: {          // See the solidity docs for advice about optimization and evmVersion
     //  optimizer: {
     //    enabled: false,
     //    runs: 200
     //  },
     //  evmVersion: "byzantium"
     // }
   }
 }
}

這是我擁有的智能合約：

pragma solidity >=0.4.18;

Contract HelloWorld {

   function hi() public pure returns (string) {

       return (“Hello World”);

   }

}

我的 2_deploy_contracts.js：

var HelloWorld = artifacts.require("./HelloWorld.sol");
module.exports = function(deployer) {
  deployer.deploy(HelloWorld);
};

當我執行 truffle compile 時，沒有任何反應，而且 truffle migrate 也不會返回任何資訊。我嘗試使用 ganache 而不是 geth 節點。儘管如此，它仍然無法正常工作。我正在從我的 macbook pro 筆記型電腦執行節點。我不確定是否需要打開埠或契約有問題。請幫忙

在此先感謝 skr

謝謝你。松露編譯失敗，因為我的帳戶沒有執行命令的權限。我對 truffle 的配置和安裝文件所在的文件夾沒有執行權限。但是，松露從未抱怨過。但是，當我以 sudo（不推薦）執行命令時，它起作用了，我得到了項目的建構文件夾。然後，我繼續更改文件夾的權限，讓我的帳戶具有執行權限。然後，Truffle compile 和 Truffle migrate 都執行良好。要確保的另一件重要事情是您在 truffle-config.js 中使用正確的埠號，這是我一開始的問題。此外，請確保您使用相應solidity 版本中可用的語法。

您的 truffle-config.js 有幾個問題：

1. 將報價添加到您的錢包地址：

來自：‘0x2e0d45a887c8120d7bc6a3d06aec5214270902ba’， 2. 你可能仍然需要錢包的提供者：

提供者: () => new HDWalletProvider(助記符, https://rpc-mumbai.matic.today),

這是我配置的一部分的範例。

嘗試一下，希望它有所幫助。
