用松露執行solidity-coverage會出錯：找不到’coverageEnv/migrations'

執行solidity-coverage 會出現以下錯誤：

$npm run coverage
...
Writing artifacts to ./build/contracts


Launched testrpc on port 8555
Running: node --max-old-space-size=4096 ../node_modules/.bin/truffle test --network coverage ../tests/test0.js

.solcover.js

module.exports = {
   copyPackages: ['zeppelin-solidity'],
   compileCommand: 'node --max-old-space-size=4096 ../node_modules/.bin/truffle compile --network coverage',
   testCommand: 'node --max-old-space-size=4096 ../node_modules/.bin/truffle test --network coverage ../tests/test0.js',
   port: '8555',
   skipFiles: []
};

松露配置：…

module.exports = {
 networks: {
   ...
   coverage: {
     host: 'localhost',
     network_id: '*', // eslint-disable-line camelcase
     port: 8555,
     gas: 0xfffffffffff,
     gasPrice: 0x01,
   }
 },
};

執行 testrpc 和手動測試就可以了。但是當使用solidity-coverage 執行時，由於某種原因它無法migrations在coverageEnv.

任何指示將不勝感激。謝謝！

編輯：

雖然可能有更優雅的方法來修復它，但我設法通過複製遷移腳本作為 testCommand 的一部分來解決這個問題：testCommand: 'cp -a ../migrations ../coverageEnv && node --max-old-space-size=4096 ../node_modules/.bin/truffle test --network coverage ../tests/test0.js',

Solidity-coverage 根據您的文件夾目錄創建一個臨時目錄，我建議將您的測試命令更改為您的測試目錄的路徑，而不是特定文件。

通常我使用 openzeppelin-solidity 而不是 zeppelin-solidity。

你的文件目錄是什麼樣的？

在文件中.solcover.js：

1. 更改zeppelin-solidity為openzeppelin-solidity
2. 更改.bin/truffle為truffle/build/cli.bundled.js（2 次出現）
