我在 Ubuntu VM 上运行它。

有谁知道为什么这可能会破坏？我在任何地方都找不到此类问题的任何示例。我正在使用我的班级提供的虚拟机，似乎没有其他人遇到过这个问题。

是否有任何资源可以解决此类问题？

我遇到了同样的问题。

如您的错误消息所示，该错误是由于 Blockchain.initChainAndGetAddress (/usr/local/lib/node_modules/embark/lib/blockchain.js:69:45) 造成的。

解决方法： 1. sudo gedit /usr/local/lib/node_modules/embark/lib/blockchain.js

  1. 找到第 69 行，就可以看出问题出在哪里。正如你在第 56 行看到的那样'//检查一个帐户是否已经存在，如果不存在则创建一个，返回地址'，如果你没有任何帐户，它应该属于第 58 行的条件。但是，在你的情况下，运行第 57 行后的结果是 'WARN [04-18|17:45:59] No etherbase set and no account found as default' 并且它与无帐户条件不匹配。因此，您只需将第 58 行中的条件从 'if (result.output === undefined || result.output === '' || result.output.indexOf("Fatal") >= 0)' 更改为'if (result.output === undefined || result.output === '' || result.output.indexOf("Fatal") >= 0 || result.output.indexOf("没有etherbase集也没有账户发现为默认值") >= 0)'。

希望这可以帮助。
