无法将 HelloWorld 合同部署到我的网络 (testrpc)
Cannot deploy HelloWorld contract to my network (testrpc)
请原谅我的基本问题，我还需要什么来部署我的合约？
我有 简单的 Hello World 合约 定义如下
HelloWorld.sol:
pragma solidity ^0.4.17;
contract HelloWorld{
function sayHello() internal pure returns(string){
return("Hello 2018!");
}
}
初始migrations.js:
var Migrations = artifacts.require("./Migrations.sol");
var HelloWorld = artifacts.require("./HelloWorld.sol");
module.exports = function(deployer) {
deployer.deploy(Migrations);
deployer.deploy(HelloWorld);
};
最后因为我使用松露，truffle.js:
module.exports = {
networks: {
development: {
host: "localhost",
port: 8545,
network_id: "*" // Match any network id
}
}
};
当我运行命令时：
truffle compile
truffle migrate
然后转到控制台：
truffle console
我使用 js:
var hw
HelloWorld.deployed().then(function(deployed){hw=deployed;});
我明白了
Error: HelloWorld has not been deployed to detected network
(network/artifact mismatch)
at C:\Users\Kofola\AppData\Roaming\npm\node_modules\truffle\build\cli.bundled.js:317116:17
at
at process._tickDomainCallback (internal/process/next_tick.js:228:7)
如何正确部署我的合约并测试它的方法？
我还应该补充一点，我的 testrpc 服务器 运行ning 在 8545，一切似乎都很好。 （所有这些都是 运行ning 在本地主机上）
我已尝试指定网络 ID，我明确设置了 ID 并在 truffle.js 中指定，但仍然无法正常工作。我还尝试更改函数的可见性。

一些尝试：
- Truffle 在 Windows 10 上有一个小问题 运行ning，其中
truffle.js 与主 truffle 命令有名称冲突。您需要将 truffle.js 重命名为 truffle-config.js 请参阅 this。
- 清除之前的所有内容builds/migrations。删除
build目录和运行truffle migrate --reset.
- 如果前 2 个不起作用，请重新启动
testrpc 以清除本地区块链上的所有先前迁移。然后再运行truffle migrate

解决方案：对于那些可能有同样问题的人阅读已接受答案的评论以获取所有信息。
工作代码，使用命令 运行 它： https://github.com/TomasBisciak/EthereumHelloWorldExample
您的 truffle migrate 命令显示未部署任何内容。您的输出应如下所示：

一些尝试：
- Truffle 在 Windows 10 上有一个小问题 运行ning，其中
truffle.js与主truffle命令有名称冲突。您需要将truffle.js重命名为truffle-config.js请参阅 this。 - 清除之前的所有内容builds/migrations。删除
build目录和运行truffle migrate --reset. - 如果前 2 个不起作用，请重新启动
testrpc以清除本地区块链上的所有先前迁移。然后再运行truffle migrate
