Ich bin dies auf einer Ubuntu VM ausgeführt.an Bord Demo funktioniert nicht

Hat jemand eine Idee, warum das brechen könnte? Ich kann nirgendwo Beispiele für diese Art von Problem finden. Ich benutze eine VM, die von meiner Klasse bereitgestellt wird und es scheint nicht, als ob jemand anderes auf dieses Problem gestoßen wäre.

Gibt es Ressourcen für die Behebung solcher Probleme?

Ich habe das gleiche Problem.

Der Fehler ist auf Blockchain.initChainAndGetAddress (/usr/local/lib/node_modules/embark/lib/blockchain.js:69:45) zurückzuführen, wie in Ihrer Fehlermeldung gezeigt.

Lösung: 1. sudo gedit /usr/local/lib/node_modules/embark/lib/blockchain.js

  1. Suche Linie 69 und Sie können, wo das Problem sehen ist. Wie Sie in Zeile 56 'sehen können // überprüfen Sie, ob ein Konto bereits existiert, erstellen Sie ein wenn nicht, Adresse zurückgeben', wenn Sie kein Konto haben, sollte es in die Bedingung in Zeile 58 fallen. In Ihrem Fall, Das Ergebnis nach der Zeile 57 lautet 'WARN [04-18 | 17: 45: 59] Es wurden keine Etherbase-Sets und keine Accounts als Standard gefunden' und es stimmt nicht mit dem Status des Nicht-Accounts überein. Sie müssen also nur die Bedingung in Zeile 58 von 'if (result.output === undefined || result.output ===' '|| result.output.indexOf ("Fatal")> = 0)' zu ändern 'if (result.output === undefiniert || result.output ===' '|| result.output.indexOf ("Fatal")> = 0 || result.output.indexOf ("Kein etherbase set und keine accounts als Standard gefunden ")> = 0) '.

Hoffe, das hilft.
