1.安装solc
npm install -g solc
用IDEA编译sol时出现错误
solcjs.cmd --abi --bin CloudNoteService.sol -o C:\Users\Administrator\IdeaProjects\test
CloudNoteService.sol:1:1: ParserError: Source file requires different compiler version (current compiler is 0.5.10+commit.5a6ea5b1.Emscripten.clang - note that nightly builds are considered to be strictly less than the released version
pragma solidity ^0.4.22;
2.solcjs.cmd --version//查看solc版本
0.5.10+commit.5a6ea5b1.Emscripten.clang
3.npm uninstall solc//卸载
4.npm install -g solc@0.4.24//安装solc0.4.24版本
5.C:\nodejs\node_modules\npm>solcjs.cmd --version//查看solc版本
0.4.24+commit.e67f0147.Emscripten.clang
6.solc跟web3一样，有版本的区别。
