我在Rails 5应用中遇到路由错误，渲染或重定向页面需要几秒钟。

我如何调试它以及什么是sockjs-node / info？
答案 0 :(得分：2)
我最近也碰到了这个。它是在我在localhost：3000上构建rails5 api之后开始的。
在我开始使用另一个使用localhost：3000的无关项目后，我开始收到此错误。
要解决此问题，我暂时只指定了另一个端口rails server -p 8000
除此之外，我还没弄清楚如何修复它。

from discord.ext import commands
class Cog01(commands.Cog):
def __int__(self, client):
self.client = client
@commands.Cog.listener()
async def on_ready(self):
for guild in self.client.guilds:
await guild.system_channel.send("I'm ready to go!")
def setup(client):
client.add_cog(Cog01(client))
由sockjs-node使用。
为避免路由错误，请确保Webpack使用的端口与默认使用的Rails服务器Puma使用的端口不同。即使在其他端口上，资产仍然可用。
对于webpack-dev-server，请检查webpack-dev-server：
config/webpacker.yml如果使用默认的dev_server:
https: false
host: localhost
port: 3035
public: localhost:3035
hmr: false
，请选中rails server：
config/puma.rb
