我正在尝试将Rails应用程序部署到Heroku，并且构建成功，但是当我打开应用程序时显示应用程序错误。
不确定我在做什么错，我可以通过Rails服务器在本地运行它并启动它，但是在部署到Heroku时会抛出错误
好的。我更新了一些内容，当我下雨时，我得到以下内容？如果有人可以帮助。

答案 0 :(得分：4)
heroku控制台给您的错误更多地是Heroku生产规则：
警告＃1
您的gemfile中有一个import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.net.NetworkInterface;
import java.util.ArrayList;
import java.util.Enumeration;
import java.util.List;
import javax.swing.DefaultComboBoxModel;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingWorker;
import javax.swing.WindowConstants;
public class SwngWrkr implements Runnable {
private JComboBox<Object> combo;
private JFrame frame;
public void run() {
showGui();
}
private JPanel createMainPanel() {
JPanel mainPanel = new JPanel();
mainPanel.add(new JLabel("Interfaces"));
DefaultComboBoxModel<Object> model = new DefaultComboBoxModel<Object>();
model.addElement("Loading...");
combo = new JComboBox<Object>(model);
mainPanel.add(combo);
return mainPanel;
}
private void showGui() {
frame = new JFrame("SW");
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.add(createMainPanel(), BorderLayout.CENTER);
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
new GetIfTsk(combo).execute();
}
public static void main(String[] args) {
SwngWrkr instance = new SwngWrkr();
EventQueue.invokeLater(instance);
}
}
class GetIfTsk extends SwingWorker<Void, Void> {
private JComboBox<Object> combo;
private List<Object> netIfNames;
public GetIfTsk(JComboBox<Object> combo) {
this.combo = combo;
netIfNames = new ArrayList<>();
}
protected Void doInBackground() throws Exception {
Enumeration<NetworkInterface> ifs = NetworkInterface.getNetworkInterfaces();
int ndx = 0;
while (ifs.hasMoreElements()) {
NetworkInterface ni = ifs.nextElement();
String name = ni.getName();
System.out.printf("%2d. %s%n", ++ndx, name);
netIfNames.add(name);
}
return null;
}
protected void done() {
DefaultComboBoxModel<Object> model = (DefaultComboBoxModel<Object>) combo.getModel();
model.removeAllElements();
model.addAll(netIfNames);
model.setSelectedItem(netIfNames.get(0));
}
}
。我有同样的错误，必须将其删除，以使其与heroku pushs不能混淆。
请参阅Heroku Removing Gemfile.lock because it was generated on Windows
警告＃2 Heroku尚未为您的应用检测到存储桶。告诉您的是，如果您上传文件，图像或任何可上传文件，则不会花费太多时间。您只会看到它几分钟，然后它会消失。我推荐一些AWS Bucket服务，您可以在这里查看：https://medium.com/alturasoluciones/setting-up-rails-5-active-storage-with-amazon-s3-3d158cf021ff
警告＃3 该警告与第二个警告有关，您需要为activeStorage添加Herokus buildpack：
x86-mingw32每当您有两种类型的环境时，您都需要具有单独的内部版本才能使每种环境都能正常工作。 请参阅： https://blog.heroku.com/rails-active-storage https://github.com/heroku/heroku-buildpack-activestorage-preview
警告＃4 这是一个公共错误，不会影响您的代码，但有时很烦人。该错误指定使用procfile，在该文件中，您需要指定用于启动应用程序的文件。在这种情况下，大多数Rails Apps都是美洲豹。我强烈建议您查看：https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server
按照以下简单步骤进行操作，以便heroku知道您正在使用什么服务来启动heroku应用。
希望这对您有用。编码愉快！
