我在Ubuntu VM上运行这个。启动演示不工作

有没有人有任何想法，为什么这可能会打破？在任何地方我找不到任何这类问题的例子。我使用的是我的课程提供的虚拟机，似乎并没有其他人遇到这个问题。

是否有任何资源来解决这样的问题？

我得到了同样的问题。

错误归因于Blockchain.initChainAndGetAddress（/usr/local/lib/node_modules/embark/lib/blockchain.js:69:45），如错误消息中所示。

解决方案： 1.须藤的gedit /usr/local/lib/node_modules/embark/lib/blockchain.js

  • 查找线69和可以看到问题是。正如你可以在第56行看到的//检查一个账户是否已经存在，创建一个账户，如果没有，返回地址'，如果你没有任何账户，它应该属于第58行的条件。但是，对于你的情况，运行第57行之后的结果是'WARN [04-18 | 17：45：59]没有设置etherbase并且没有找到默认账户“，并且它与no账户条件不匹配。所以你只需要将第58行的条件从'if（result.output === undefined || result.output ===''|| result.output.indexOf（“Fatal”）> = 0）'改为'if（result.output === undefined || result.output ===''|| result.output.indexOf（“Fatal”）> = 0 || result.output.indexOf（“没有etherbase集并且没有账户发现为默认“）> = 0）'。

    • 希望这会有所帮助。
