错误:rb_gc()上的跨线程冲突 [英] Error: cross-thread violation on rb_gc()

问题描述

我是Ruby on Rails的新手.

I'm new to Ruby on Rails.

当我使用Rails创建博客教程时，我在终端中运行了以下内容:

I ran the following in a terminal when I was going through creating a blog tutorial with Rails:

$ rails blog
[BUG] cross-thread violation on rb_gc()
(null)

Abort trap

如何确定此错误消息的含义以及如何解决?

How do I determine what this error message means and how to fix it?

更新

我做了些摆弄，但我再也没有收到错误消息.但是我确实注意到我的环境现在正在运行Ruby的另一条路径.

I did some fiddling and I'm not getting the error message anymore. But I do notice that my environment is running a different path of Ruby now.

这似乎意味着我在Mac盒子上安装了多个Ruby.在/opt/local/bin/和/usr/bin/中.我认为前者来自MacPorts安装，后者是我的系统附带的(可能已升级).

This seems to imply that I have multiple installs of Ruby on my Mac box. One in /opt/local/bin/ and /usr/bin/. I think the former came from a MacPorts install, and the latter is what came with my system (possibly upgraded).

推荐答案

问题是我的系统上有多个ruby安装/路径.我相信Mac OS X Snow Leopard预先安装了红宝石.我误以为使用MacPorts来安装更新的版本.

The problem was that I had multiple installs/paths of ruby on my system. Mac OS X Snow Leopard comes with ruby pre-installed I believe. I made the mistake of using MacPorts to install a newer version, right alongside.

我通过以下方式解决了该问题:

I fixed the problem by:

1. 从Macports卸载ruby版本
2. 安装 Ruby Version Manager (又称rvm)，以帮助我管理多个ruby安装. (可选，但推荐)

1. Uninstalling the version of ruby from Macports
2. Installing Ruby Version Manager, aka rvm, to help me manage multiple ruby installs. (optional, but recommended)

我还将其发布在Ruby on Rails Talk上.参见错误: rb_gc()上的跨线程冲突

I also posted this on Ruby on Rails Talk. See Error: cross-thread violation on rb_gc()
