它似乎在寻找libmagic.so.1文件.我有那个档案.它位于/ usr/lib64中.我没有以root用户身份运行此安装.

我也在使用rvm和Bundler.这是我的"bundle"命令的结果,当它到达我的Gemfile中的ruby-filemagic行时:

[server@mine ext]$ ruby extconf.rb --with-magiclib
checking for magic_open() in -ltrue... no
*** ERROR: missing required library to compile this module
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

更新:

以下是mkmf.log的结果:

have_library: checking for magic_open() in -ltrue... -------------------- no

我遇到了Virtualbox问题

Callee RC:REGDB_E_CLASSNOTREG"(0x80040154)

突然间.在VirtualBox 4.3上开始出现问题(我认为).我升级到版本5希望修复它,但在那一点上没有运气.

我正在尝试将几个计算引擎实例从欧洲迁移到亚洲.我需要这样做,因为这些服务器的大多数用户都在亚洲,他们可以更快地访问他们所在地区的服务器.我正在尝试遵循命令.

gcloud compute instances move asiawindows1 --zone europe-west1-d  --destination-zone asia-east1-c

我尝试这个时出现以下错误

属于子网的实例无法在区域间移动.

移动这些服务器而不在亚洲区域手动设置它们的最佳方法是什么？

我的CKEditor代码是

window.onload = function()
{
    var editor = CKEDITOR.replace( \'big_info\' );
    CKEDITOR.config.height = \'330px\';
    CKEDITOR.config.toolbar_Full =
    [
        [\'Source\',\'-\',\'Templates\'],
        [\'Maximize\', \'ShowBlocks\'],
        [\'Cut\',\'Copy\',\'Paste\',\'PasteText\',\'PasteFromWord\',\'-\',\'SpellChecker\', \'Scayt\'],
        [\'Undo\',\'Redo\',\'-\',\'Find\',\'Replace\',\'-\',\'SelectAll\',\'RemoveFormat\'],
        [\'TextColor\',\'BGColor\'],

        [\'NumberedList\',\'BulletedList\',\'-\',\'Outdent\',\'Indent\',\'Blockquote\'],
        \'/\',
        [\'Bold\',\'Italic\',\'Underline\',\'Strike\',\'-\'],
        [\'Styles\',\'Format\',\'Font\',\'FontSize\'],
        [\'JustifyLeft\',\'JustifyCenter\',\'JustifyRight\',\'JustifyBlock\'],
        [\'Link\',\'Unlink\',\'Anchor\'],
        [\'Image\',\'Flash\',\'Table\',\'HorizontalRule\',\'PageBreak\']
    ];

    CKFinder.SetupCKEditor( editor, { BasePath : \'/javascript/ckfinder/\', RememberLastFolder : false } ) ;
};

我想获取编辑框的内容并通过我的jQuery脚本中的JSON发送它.我找不到怎么做.

我在Mac(10.6.8)上遇到了Ruby(1.9.3),Rails和Postgres(9.0.8)的设置.每次运行时rails console我都会收到以下错误:

我是Rails和Puma的新手,所以这个问题可能因为简单的解决方案而过于愚蠢,如果你认为我做错了什么也请指导我.

我正在尝试为工作人员启动Puma服务器.如果我将工人设置为0

puma -w0

服务器启动完美,但如果我将worker设置为1或更多,则会出现以下错误:

OSX/Monterey/M1/Arm/Homebrew：我一生都无法让它工作：

./configure --with-jemalloc

它死了

checking jemalloc/jemalloc.h presence... no
configure: error: jemalloc requested but not found

即使它就在那里：/opt/homebrew/Cellar/jemalloc/5.2.1_1/include/jemalloc/jemalloc.js。

brew --prefix jemalloc一切看起来都是jemalloc-config --includedir正确的。

我尝试过各种版本：

export RUBY_CONFIGURE_OPTS="--with-jemalloc-include=$(brew --prefix jemalloc)/include

和/或

./configure --with-jemalloc-include=$(brew --prefix jemalloc)/include

但没有骰子。甚至不确定这些环境变量/标志是否受到 ruby​​ 的尊重，或者它们是否是一些 rvm/rbenv/ruby-build 的东西。

我打算直接使用 ruby​​ 的配置而不是 rvm/build 工具进行所有测试。

我正在尝试在 macOS 12.5 上安装 Ruby 3.1.2，使用 chruby 作为我的版本管理器。

运行ruby-install ruby，我收到此错误：

>>> Extracting ruby-3.1.2.tar.xz to /Users/justin/src/ruby-3.1.2 ...
/usr/local/bin/../share/ruby-install/util.sh: line 56: xzcat: command not found

>>> Regenerating ./configure script ...

!!! Configuration of ruby 3.1.2 failed!

我不太确定如何解决这个问题。有人可以给我一些建议吗？

我一直在努力让twitter-bootstrap-rails gem在我的windows机器上工作,并且在尝试安装'therubyracer'宝石时遇到了错误,这是一个较旧版本的较少宝石的依赖.

我认为升级到较低的2.2.1,这不依赖于therubyracer,但尽管它似乎认为我仍然需要安装therubyracer.这是我尝试启动rails服务器'rails s'时得到的错误输出.

$ rails s

这在 Rails 6 中运行良好，但现在将 Rails 和 Ruby 升级到 6.11 和 3，它触发了这个“经典”错误。基本上，简而言之，例如这个外部 URL 直接指向 Firefox 徽标，使用 Rails 控制台：

require 'open-uri'
open("https://brandemia.org/sites/default/files/inline/images/firefox_logo.jpg")

Traceback (most recent call last):
        4: from (irb):1:in `<main>'
        3: from (irb):2:in `rescue in <main>'
        2: from (irb):2:in `open'
        1: from (irb):2:in `initialize'
Errno::ENOENT (No such file or directory @ rb_sysopen - https://brandemia.org/sites/default/files/inline/images/firefox_logo.jpg)

在应用程序中相同的错误。在 Rails 和 Ruby 升级（使用 Ruby 2.5.8 和 Rails 6.0.3.1）之前，这工作得很好。
