无法通过松露部署到Rinkeby -无法读取属性“bind”

Question

我正在使用松露："^4.1.14“和ganache-cli版本"^6.1.8”。当我尝试迁移到ganache cli网络时，它没有问题。但是当我试图迁移到Rinkeby时，它总是失败的。错误消息是TypeError: Cannot read property 'bind' of undefined。这条有问题的线埋在webpack的某个地方，我无法找到那个脚本来检查它或console.log它。

truffle.js的相关部分如下所示

rinkeby_infura: {
      provider: function() {        
        // using process.env.MNENOMIC would be safer, but this is test project
        const mnemonic = require('./.mnemonic');
        const apiKey = require('./.infura_api_key');
        return new HdWalletProvider(mnemonic, 'https://rinkeby.infura.io/' + apiKey);
      },
      network_id: 4,      
      gas: 4612388 // Gas limit used for deploys
    },

异常的完整堆栈跟踪如下。这可能与连接到Rinkeby的提供商有关，至少从我搜索到的情况来看是这样的。但我无法让它发挥作用。

$ ./node_modules/.bin/truffle migrate --network rinkeby_infura

在我看来，在打开助记符/英弗拉API密钥文件时遇到了问题。如果直接使用助记符和API键而不是变量，它是否有效？

此外，我建议您使用dotenv和process.env (即使使用测试项目)，这样可以更容易地处理将来的更新！
