Blockchain 无法将HelloWorld协定部署到我的网络(testrpc)
请原谅我的基本问题,巴德,我还需要什么来部署我的合同 我的简单Hello World合同定义如下 HelloWorld.sol:Blockchain 无法将HelloWorld协定部署到我的网络(testrpc),blockchain,ethereum,solidity,truffle,Blockchain,Ethereum,Solidity,Truffle,请原谅我的基本问题,巴德,我还需要什么来部署我的合同 我的简单Hello World合同定义如下 HelloWorld.sol: pragma solidity ^0.4.17; contract HelloWorld{ function sayHello() internal pure returns(string){ return("Hello 2018!"); } } Initial migrations.js: var Migrations = a
pragma solidity ^0.4.17;
contract HelloWorld{
function sayHello() internal pure returns(string){
return("Hello 2018!");
}
}
Initial 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,由于我使用的是块菌,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
错误:HelloWorld尚未部署到检测到的网络
(网络/工件不匹配)
位于C:\Users\Kofola\AppData\Roaming\npm\node\u modules\truffle\build\cli.bundled.js:317116:17
在
在进程中。_tickDomainCallback(internal/process/next_tick.js:228:7)
如何正确部署合同并测试其方法?
我还应该补充一点,我的testrpc服务器运行在8545,一切似乎都正常。(所有这些都在本地主机上运行)
我试图指定网络的id,我显式地设置了id并在truffle.js中指定,但仍然不起作用。我还试图改变函数的可见性
编辑“块菌命令的输出”:

在evalmachine上。您的truffle migrate
命令显示未部署任何内容。您的输出应该如下所示:
有些事情可以尝试:
Truffle在Windows 10上运行时存在一个小问题,Truffle.js
与主Truffle
命令的名称冲突。您需要将truffle.js
重命名为truffle config.js
请参阅
清除所有以前的生成/迁移。删除build
目录并运行truffle migrate--reset
如果前两个不起作用,请重新启动testrpc
,清除本地区块链上以前的任何迁移。然后重新运行truffle migrate
您可以添加来自trufflecompile
和migrate
命令的输出吗?还有,你在什么操作系统上运行这个?通常,您希望将部署放在2_deploy_contracts.js中,而不是1_initial_migrations.js中,但我认为这不是您的问题。@Adam Kipnis我在Win10 Home 64位上运行。这个项目是用命令truffle init初始化/创建的,警告输出也不相关,现在显示这些只是因为我编辑了可见性。我的问题中的代码没有警告,但仍然是相同的错误。好吧,发生了一些事情,一旦我运行了你的命令--reset,它说编译。。。。等然后我进入testrpc服务器,按下ctrl+c(我想退出),在控制台中看到执行开始继续,我看到了您期望的输出,部署helloworld。。。等现在,当我调用该方法时,返回的是“”,而不是“Hello 2018”。在测试rpc控制台上,当我调用方法sayHello时,我看到eth_调用。我们正朝着正确的方向前进:D BUD尚未到达:D您是否将可见性从内部
更改回公共
?您无法使用internal
可见性从客户端调用sayHello()
。我已将我的函数sayHello编辑为“函数sayHello()返回(字符串){…”另外,我的项目目录包含truffle-config.js,默认为空。我所做的是,我在其中放入了与truffle.js相同的内容,我不确定这是否有任何效果。是的。…truffle-config.js
应该与truffle.js
相同。这只是一个文件重命名。更改合同中的可见性之后(然后重新运行compile
和migrate
),键入hw
(从更长的输出中截断)后,您应该会在控制台中看到以下输出:sayHello:{[Function]call:[Function],sendTransaction:[Function],request:[Function:bound],estimateGas:[Function]},我现在明白了。Bud仍然无法运行我的方法并打印正确的消息
