Eventmachine gem安装失败

Question

我无法安装eventmachine

好的,我知道这已被问了很多,但到目前为止我找不到任何解决方案帮助了我.所以我作为最后的手段在这里发布.

我使用( windows 8 x64通过ruby 2.0.0p195 (x64)Ruby Installer for Windows安装适当的Devkit)

所以错误是

事情我已经尝试把gem "eventmachine", "~> 1.0.3"或gem "eventmachine", "~> 1.0.0.beta.4.1"在我的Gemfile和删除/修改从EventMachine的gemfile.lock 制作新testapp和instaling EventMachine的有(失败)

我怀疑的事情我追踪了事件机器的依赖关系(可以在Rubygems上找到),我看到我既不能安装蓝布(显示更大的日志错误),也不能安装tidy-ext(bluecloth depencency)所以我认为它可能有一些相关性,也无法安装瘦

如有任何信息,请询问

谢谢大家!!

Answer 1

我可以安装它,执行以下步骤:

1)尝试正常安装:

gem install eventmachine

它获取了gem的1.0.3版本,但是由于变量声明的混乱而在make中失败了

2)编辑文件:

c:\Ruby200-x64\lib\ruby\gems\2.0.0\gems\eventmachine-1.0.3\ext\project.h

并评论了第97行

//typedef int pid_t;

要获得更强大的修正,请在此处查看解决方案https://github.com/eventmachine/eventmachine/pull/450/files

3)然后,我打开了命令提示符,然后转到gem文件夹

c:\Ruby200-x64\lib\ruby\gems\2.0.0\gems\eventmachine-1.0.3

并运行:

gem build eventmachine.gemspec

您需要在PATH中使用git.exe位置安装git才能使其正常工作(例如C:\ Users\YourUsername\AppData\Local\GitHub\PORTAB~1\bin).

4)它在文件夹上生成了一个eventmachine.gem文件...所以我把文件复制到了ac:\ tmp文件夹,然后转到那个文件夹,然后我输入了:

gem install eventmachine-1.0.3.gem --local

它安装成功!

Answer 2

这对我有用:

brew link openssl --force 

Answer 3

我收到如下错误

C:\ Ruby200-x64\lib\ruby​​\gems\2.0.0\gems\eventmachine-1.0.3> gem build eventmachine.gemspec [eventmachine.gemspec]中的gemspec无效:没有这样的文件或目录 - git ls-files

错误:加载gemspec时出错.中止.

但是,我保持project.h在textpad中打开并尝试做gem install eventmachine.有一次,当从gem install命令获取新文件时,textpad将要求确认重新加载project.h ..只需重新加载并注释行// typedef int pid_t; ..然后编译经过..

基本上,在获取gem项目文件后需要一段时间才能开始编译.只是利用那个时间评论htis线..它对我有用..可能不适合每个人.

干杯!

Answer 4

尝试

gem install eventmachine -- --with-cppflags=-I/usr/local/opt/openssl/include

Answer 5

我遇到了同样的问题，并通过在开头添加以下内容成功运行它Gemfile：

gem 'eventmachine', :git => 'git://github.com/eventmachine/eventmachine.git', :branch => 'master'

在此之前我卸载了eventmachine.
