我试图编译这段代码:
contract C {
struct s {
string chan;
string content;
}
s[] x = new s[](0);
}
它给我带来了一个令人困惑的编译器错误:
Unimplemented feature:
/solidity/libsolidity/codegen/ArrayUtils.cpp(237): Throw in function solidity::frontend::ArrayUtils::copyArrayToStorage(const solidity::front
不知道到底是怎么回事,但是我不能再用abigen来生成Go Ethereum绑定了,我得到了一个错误,上面写着EvalSymlinks: too many links
solidity@pop-os:~/Documents/Code/RTrade/Mining-Stake/solidity$ abigen -abi TokenLockupV2.abi -bin TokenLockupV2.bin -out test.go -pkg Test
EvalSymlinks: too many links
SyntaxError: Source file requires different compiler version (current compiler is 0.4.19+commit.c4cbbb05.Emscripten.clang - note that nightly builds are considered to be strictly less than the released version
pragma solidity 0.4.15;
^---------------------^
合同:
pragma solidity ^0.4.19;
contract Info {
/* some other setters */
function ageOf(uint256 _tokenId) public view returns (uint256 age) {
return ages[_tokenId];
}
function ownersAddress(uint256 _tokenId) public view returns (address addr);
}
然后,我有了组件:
class Parent extends React.c
我正在尝试设置一个bitbucket管道,它使用一个docker run语句。但是,生成失败的错误消息如下:
docker: Error response from daemon: authorization denied
这是管道配置
pipelines:
default:
- step:
script:
# build the Docker image (this will use the Dockerfile in the root of the repo)
- docker build -t solc .
我使用truffle develop与MetaCoin教程契约进行交互。几个月前,我在一款较旧版本的松露上做过这件事,而且效果很好。
但是现在,每当我尝试使用“等待”时,我都会得到相同的错误。在本教程之后,我尝试了一个全新的MetaCoin应用程序安装,而且我自己的合同都是从头开始编写的,没有什么是可行的。
truffle(develop)> let accounts = await web3.eth.getAccounts()
Uncaught ReferenceError: global is not defined
at evalmachine.<anonymous>
我是新手,所以我的问题可能很简单。我有两个合同"BankA“和"customer”。每当我在BankA开发环境中部署pay()并调用D0时,就会出现以下错误:
Error: Returned error: VM Exception while processing transaction: revert at PromiEvent (C:\Users\lenovo\AppData\Roaming\npm\node_modules\truffle\build\webpack:\packages\contract\lib\promievent.js:9:1)
解决办法是什么。
我一直遇到这个问题,我不知道为什么它总是告诉我导入web3是无法解决的,不管我尝试了多少次重新安装和安装它,请帮助我,如果有人可以--这是代码
from solcx import compile_standard, install_solc
import json
from ***web3*** import Web3
with open("./SimpleStorage.sol") as file:
simple_storage_file = file.read()
print(simple_storage_file)
# Compile our sol
我正在尝试安装和使用由ConsenSys编写的python解析器
我继续得到以下错误
File "<stdin>", line 1, in <module> File "/home/seed/.local/lib/python3.5/site-packages/python-solidity-parser/solidity_parser/__init__.py", line 1, in <module> from .parser import parse_file, parse, objectify, visit
我正在尝试安装和使用,pip3安装没有给出错误,但当我尝试导入模块时,它显示
File "<stdin>", line 1, in <module>
File "/home/seed/.local/lib/python3.5/site-packages/python-solidity-parser/solidity_parser/__init__.py", line 1, in <module>

我试图在VScode中运行一个简单的代码。

pragma solidity ^0.8.0;

contract WavePortal {

当我试图编译代码时,它显示了以下错误
