Truffle
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", port:8545 }, 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: "*", from: 0x2e0d45a887c8120d7bc6a3d06aec5214270902ba, gas:8500000, gasPrice:2000000000, // Any network (default: none) }, // Another network with more advanced options... // advanced: { // port: 8777, // Custom port // network_id: 1342, // Custom network // gas: 8500000, // Gas sent with each transaction (default: ~6700000) // gasPrice: 20000000000, // 20 gwei (in wei) (default: 100 gwei) // from: <address>, // Account to send txs from (default: accounts[0]) // 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. // ropsten: { // provider: () => new HDWalletProvider(mnemonic, `https://ropsten.infura.io/${infuraKey}`), // network_id: 3, // Ropsten's id // gas: 5500000, // Ropsten has a lower block limit than mainnet // confirmations: 2, // # of confs to wait between deployments. (default: 0) // timeoutBlocks: 200, // # of blocks before a deployment times out (minimum/default: 50) // 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. // production: true // Treats this network as if it was a public net. (default: false) // } }, // 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:
- 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,

),這是我配置的一部分的範例。
嘗試一下,希望它有所幫助。
