ganache跟 hardhat 一样，是运行在本地的ethereum网络。不一样的是，ganache 带有友好的操作界面。具备explorer，这个太给力了。
注意事项
1. 务必安装好一个nodejs , 例如16.x 这样ganache才可以查看truffle项目中的contract
2. 关掉防火墙（如果你是在虚拟机，wsl 或者docker中使用的话） 否则无法访问ganache rpc server
3. 特别特别注意：关掉Linux 下的代理（例如http_proxy, https_proxy ） 否则无法访问ganache rpc server
windows下的安装方式
1. 到官网，下载exe， 安装
2. 运行后，编辑它。
3. 填写个名字
4. 看一下其他配置
5. 其他选项： 记录日志，选择日志文件夹等
6. 主界面的说明
使用之前：
使用curl 命令确认是否可以访问:
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_getBalance","params": ["0xDEC781c67a86570c004c7840BE1AddAF51C39487", "latest"],"id":1}' http://192.168.10.54:3355 -vvv
Note: Unnecessary use of -X or --request, POST is already inferred.
* Trying 192.168.10.54:3355...
* TCP_NODELAY set
* Connected to 192.168.10.54 (192.168.10.54) port 3355 (#0)
> POST / HTTP/1.1

> User-Agent: curl/7.68.0
> Accept: */*

<
* Connection #0 to host 192.168.10.54 left intact
{"id":1,"jsonrpc":"2.0","result":"0x56266a7b7dbf06000"}
如果是上面这样，就没问题。
使用 浏览器打开 该地址： 如果能看到 400 Bad Request, 就说明 该server已经在运行了
7. 在truffle中使用: 修改truffle-config.js 增加对应的network:
require('dotenv').config();
const HDWalletProvider = require('@truffle/hdwallet-provider');
module.exports = {
networks: {
// 这个就是需要我们增加的
ganache: {
provider: () => new HDWalletProvider("gym host tag slow tent leopard woman emerge pear ??? ??? ???", "http://192.168.10.54:3355"),
network_id: "5777",
networkCheckTimeout: 30000,
timeoutBlocks: 200,
addressIndex: 2
},
},
compilers: {
solc: {
// version: "^0.8.0",
version: "0.8.15",
}
},
plugins: ['truffle-plugin-verify'],
api_keys: {
etherscan: '4ANBPF8KQQHJ6J9BBU7WU53BNPDMXHYJMW'
}
};
8. 运行前，确保你没有使用 http_proxy ， 例如
9. 部署：truffle deploy --network ganache --verbose-rpc --interactive --reset

可以说是非常的爽歪歪了。在本地运行速度奇快，瞬间结束（goerli等网络需要一个30秒左右）
10. 查看Ganache Dashboard
可以看出，上面出现的3个Contract Creation tx, 都依次出现在了这里（时间倒叙排序）
（创建的时间顺序： 从上到下）
MyTestNft 0x4ca4fe4f388e9b124554975c0bae0e02a1ad9f49181356b8c66dbb2ee9dbbe9d
MyTestNftB 0xef23e81d51c704699b3eb73cd846db363efbcdcbc57a41b6527429221fbc7ff8
MyTestNftC 0xf5d1849fd5356881f33b4ce696e318d47a87a8204a657bc3c1009ceafc19caa2
在Ganache 中的Transactions ：越在上面的，就是越新的 tx
点击可以查看详情：
可以看到目前还没有event
点击对应的account, 发现balance在变少
每个tx对应一个block
可以看到都已经部署了
点击 Contract的详情，就可以看到下面的页面：

最常见的问题
1. code -32603 , socket hang up
truffle deploy --network ganache
Compiling your contracts...

跟ganache 没有连通。 解决办法:
1. 重启ganache
2. 重启terminal 不要使用代理 （这里最关键, 我被这里卡了大半个下午+2小时上午+一晚上琢磨这个事儿）
3. 关闭防火墙
4. 检查truffle-config.js 中的network是否正确
