推荐答案
根据此帖子 <arpa/inet.h>
不是Windows库,因此应改用winsock2.h
.
According to this post <arpa/inet.h>
is not a windows library, so winsock2.h
should be used instead.
要更改此引用,我已完成以下操作**:
To change this reference, I've done the following**:
- 转到您的安装文件夹(c:/Ruby193/lib/ruby/gems/1.9.1/gems/bson_ext-1.11.1)
- 在cbson文件夹中深入研究并找到cbson.c
- 在您喜欢的文本编辑器中打开cbson.c并找到读取
#include "<arpa/inet.h>"
的行.
- 将该行更改为
#include winsock2.h
- 打开命令提示符,浏览到安装文件夹,然后运行
gem build bson_ext.gemspec
- 将新创建的.gem文件移动到安全的位置(例如,%userprofile%\ Desktop).
- 转到gem文件夹并删除整个bson_ext文件夹
- 返回命令提示符窗口,将目录更改为放置新创建的.gem文件的位置(如果完全按照以下步骤操作,则为cd%userprofile%\ Desktop)
- 运行
gem install bson_ext-1.11.1.gem --local
,现在应该可以成功安装gem.
- Go to your installation folder (c:/Ruby193/lib/ruby/gems/1.9.1/gems/bson_ext-1.11.1)
- Drill down a level into the cbson folder and find cbson.c
- Open cbson.c in your favorite text editor and find the line that reads
#include "<arpa/inet.h>"
- Change that line to
#include winsock2.h
- Open a command prompt, browse to the installation folder, and run
gem build bson_ext.gemspec
- Move the newly-created .gem file someplace safe (%userprofile%\Desktop, for example).
- Go up to the gem folder and delete the entire bson_ext folder
- Back in your command prompt window, change directory to wherever you placed the newly-created .gem file (cd %userprofile%\Desktop, if you're following these steps exactly)
- Run
gem install bson_ext-1.11.1.gem --local
and the gem should now install successfully.
**巨大的警告:我只是通过mongodb for rails教程运行,并且没有任何可用来测试此功能的代码.尽管这样可以消除安装错误,但我无法确定此修补程序是否完整.该库参考是1.11.1发行版的新增内容.如果安装版本1.10.2,则不会发生此问题(gem install bson_ext -v 1.10.2
).我将由您来决定哪种解决方案对您更有意义.
** Huge caveat: I am just running through a mongodb for rails tutorial and I don't have any functioning code with which to test this. While this removes the installation error, I have no way of determining if this fix is a complete one. This library reference is new for the 1.11.1 release. If you install version 1.10.2 this issue will not occur (gem install bson_ext -v 1.10.2
). I'll leave it to you to decide which solution makes more sense for you.
基于对bson-ruby项目进行的更改 github,一个更好的解决办法是更改包含如下内容的内容:
Based on a change to the bson-ruby project on github, a better fix would be to change that include to read like this:
#ifdef _WIN32
#include <winsock2.h>
#else
#include <arpa/inet.h>
#endif
