测试合约时运行断言测试失败

Question

运行命令 npm run test 时出错

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! lottery@1.0.0 test: `mocha`
npm ERR! Exit status 1

npm ERR! Failed at the lottery@1.0.0 test script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我删除了其他测试文件，因为我从以前成功运行的文件夹中复制了这个文件夹。

Answer 1

请尝试以下：

npm uninstall solc
npm install solc@x.y.z   //replace x.y.z as your target version
