Tasks: TOP => erd => erd:generate

我不明白这个问题。将应用程序从 rails 3 升级到 rails 4.2 后，我遇到了这个问题。我的应用程序运行没有任何问题。但是当我运行rake db:migrate command 时，我得到了这个错误。如何解决这个问题？

错误日志中有一行可能很重要，但我不明白。

GraphViz not installed or dot not in PATH. Install GraphViz or use the 'path' option

【参考方案1】：

Mac 用户：

brew install graphviz

【参考方案2】：

试试下面的命令。

erd --inheritance --direct --attributes=foreign_keys,content --filetype=dot
dot -Tjpg erd.dot > erd.jpg

【讨论】：

安装 graphviz 对我没有用 - 上面有

太棒了，经过数小时的研究，这已经成功了 :) 谢谢并确保事先也进行 brew install graphviz！

【参考方案3】：

这是因为您的项目正在使用Rails ERD，这是一个可以自动创建 ERD - 实体关系图的 gem。它依赖于一个名为graphviz 的库来运行。如果你想继续使用它，你必须installgraphviz。在 Linux 上，您可以通过控制台执行此操作：

sudo apt-get install graphviz

如果您不想使用 rails-erd gem，请将其从 Gemfile 和 bundle 中删除。如果您在 Gemfile 中没有看到它，请查看您的 Gemfile.lock 以确定需要 rails-erd gem 的内容并考虑删除该 gem。

【讨论】：

对我来说，即使安装了graphviz也不起作用
