1. 安装 truffle
npm install -g truffle --verbose（我在这里卡住了， 用proxy也不行，只能使用 cnpm 的方式来安装了 ）
2024.3.27
使用npm 代理：
https://stackoverflow.com/a/10304317/445908
npm config set https-proxy http://proxy.company.com:8080
使用yarn :
yarn config set http-proxy http://192.168.0.104:8072
yarn config set https-proxy http://192.168.0.104:8072
好吧，用了cnpm, 900 seconds

npm timing npm Completed in 908605ms
npm info ok
2. 在当前文件夹下，$ npm install dotenv
3. $ truffle init
$ truffle init Starting init... ================ > Copying project files to /mnt/d/workspace/test_truffle Init successful, sweet! Try our scaffold commands to get started: $ truffle create contract YourContractName # scaffold a contract $ truffle create test YourTestName # scaffold a test
可以看到，truffle 生成了这样几个文件夹：
$ find contracts/ migrations/ test/ contracts/ 智能合约 contracts/Migrations.sol 已经存在了一个文件了 migrations/ 迁移 migrations/1_initial_migration.js 已经存在了一个了 test/ 测试文件夹
4. 安装 hdwallet-provider
npm install @truffle/hdwallet-provider
5. 创建.env文件
INFURA_API_URL = "https://goerli.infura.io/v3/427a8f460d514ebfadf0d6c60b0?????" # infura的 API URL MNEMONIC = "margin blouse tenant chat hub chef addict club rather ??? ??? ??? " # metamask 助记词
metamask的助记词可以在 https://metamask.zendesk.com/hc/en-us/articles/360015290032-How-to-Reveal-Your-Seed-Phrase 这里查询到 ( 右上角 LOGO -> settings -> 隐私与安全性 -> ... )
6. 在contracts 目录下，创建 Demo.sol , 内容如下：
$ cat contracts/Demo.sol
pragma solidity >= 0.5.8;
contract Demo {
event Echo(string message);
function echo(string calldata message) external {
emit Echo(message);
}
}
7. 修改 truffle-config.js ，内容如下：
require('dotenv').config()
const HDWalletProvider = require('@truffle/hdwallet-provider')
const { INFURA_API_URL, MNEMONIC } = process.env
module.exports = {
networks: {
development: {
host: "127.0.0.1",
port: 8545,
network_id: '*'
},
goerli: {
provider: () => new HDWalletProvider(MNEMONIC, INFURA_API_URL),
network_id: 5,
gas: 5500000
}
}
};
8. 运行 truffle compile
$ truffle compile Compiling your contracts... =========================== > Compiling ./contracts/Demo.sol > Compiling ./contracts/Migrations.sol > Artifacts written to /mnt/d/workspace/test_truffle/build/contracts > Compiled successfully using: - solc: 0.5.16+commit.9c3226ce.Emscripten.clang
9. 我们回顾一下contracts 目录下
在migration 目录下，创建新文件， 内容如下：2_deploy_contract.js
const DemoContract = artifacts.require('Demo')
module.exports = function(deployer) {
deployer.deploy(DemoContract)
}
10. 部署到网络上
查看命令详情： truffle help deploy
运行： truffle deploy --network goerli --verbose-rpc --interactive
我这里没能成功，一开始是报错：
Compiling your contracts...
===========================
> Everything is up to date, there is nothing to compile.
Starting migrations...
======================
> Network name: 'goerli'
> Network id: 5
> Block gas limit: 29970705 (0x1c95111)
1_initial_migration.js

后来搜索了一下，要么是.env 变量写错了，要么是从https 切换到wss的 rpc server, 我试了不好用，后来是修改 truffle-config.js ， 内容为：
require('dotenv').config();
const HDWalletProvider = require('@truffle/hdwallet-provider');
const { INFURA_API_URL, MNEMONIC } = process.env;
module.exports = {
networks: {
development: {
host: "127.0.0.1",
port: 8545,
network_id: "*"
},
goerli: {
provider: () => new HDWalletProvider(MNEMONIC, INFURA_API_URL),
network_id: '5',
gas: 5500000,
networkCheckTimeout: 1000000, // 这里设置超时时间1000秒
timeoutBlocks: 200,
addressIndex: 2
}
}
};
然后就卡住了， 看了一下，可以在goerli 网络上找到对应的 pending contract address:
https://goerli.etherscan.io/tx/0x458646b9bfc73fe4bc856a310eeeaee9e9d7888e812acdf5820056ce36031352
不过pending的也太久了吧。。。10分钟过去了还没消息。
This txn hash was found in our secondary node and should be picked up by our indexer in a short while.
好的，750秒之后， 有消息了

Truffle v5.5.18 (core: 5.5.18)
Node v16.15.1
看起来是 750秒之后出的问题 , 迟迟没有被确认 . 不过刷新了下浏览器，这个contract已经被部署成功了（估计是 truffle没有收到 response 或者event ）
所以开始踩坑： 看了下区块链浏览器， 在我发布contract的30分钟内是没有任何block产生的。
11. 所以调高 gas价格，我们重新发布：
修改 truffle-config.js
truffle deploy --network goerli --verbose-rpc --interactive --skip-dry-run --reset
这次就可以了。
require('dotenv').config();
const HDWalletProvider = require('@truffle/hdwallet-provider');
const { INFURA_API_URL, MNEMONIC } = process.env;
module.exports = {
networks: {
development: {
host: "127.0.0.1",
port: 8545,
network_id: "*"
},
goerli: {
provider: () => new HDWalletProvider(MNEMONIC, INFURA_API_URL),
network_id: '5',
gas: 5500000,
gasPrice: 50000000000, // 50 gwei 这里特别重要
networkCheckTimeout: 1000000,
timeoutBlocks: 200,
addressIndex: 2
}
}
};
一个正常的log是这样的：

总结一下调试 需要用到的工具
1. google web browser
2. goerli.etherscan.io （查看部署后的结果）
3. 修改本地的代码 （看配置）
4. 看本地的log 输出
