您必須先部署並連結以下庫，然後才能部署新版本的 Contract

我製作了我的自定義庫並嘗試在我自己的項目中使用。

下面是 2_deploy_contracts.js

module.exports =  async(deployer, netowrk) => {
await deployer.deploy(OptionStorage, ownerAddress);
await deployer.deploy(LDerivativeFactory);
await deployer.link(LDerivativeFactory, DerivativeFactory);
await deployer.deploy(DerivativeFactory, OptionStorage.address, XToken);
};

在測試案例中，我試圖將其用作

beforeEach(async () => {
   optionStorage = await OptionStorage.new(owner);
   //library = await Library.new();
   //DerivativeFactory.link('LDerivativeFactory',library.address);
   derivativeFactory = await DerivativeFactory.new(optionStorage.address, quoteToken.address, { from : owner, gas : 50000 });
});

但是在執行測試案例時，我遇到了錯誤

錯誤：DerivativeFactory 包含未解析的庫。您必須先部署並連結以下庫，然後才能部署新版本的 DerivativeFactory： LDerivativeFactory

如何解決？我也嘗試連結測試案例，然後我遇到了不同的錯誤

錯誤：錯誤：基本費用超過 gas 限制

任何幫助都是令人欽佩的

您應該使用問題 #501中推薦的修復程序，它導致的問題是松露的工件沒有按正確的順序更新。

async function doDeploy(deployer, network) {
   await deployer.deploy(OptionStorage, ownerAddress);
   await deployer.deploy(LDerivativeFactory);
   await deployer.link(LDerivativeFactory, DerivativeFactory);
   await deployer.deploy(DerivativeFactory, OptionStorage.address, XToken);
}


module.exports = (deployer, network) => {
   deployer.then(async () => {
       await doDeploy(deployer, network);
   });
};
