问题描述

我使用Railsinstaller来安装rails，但仍然收到此错误消息.基于与此有关的其他问题，Railsinstaller似乎应该包含devkit，并且应该不会出现此问题.

I used Railsinstaller to install rails, but I still get this error message. Based on what other questions regarding this, it seems that Railsinstaller should include devkit and this problem shouldn't happen.

我做错了什么?

顺便说一句，这是我将gemfile更改为在生产中包含'pg'的时候(当然，正在开发和测试sqlite)，然后尝试运行bundle install-不生产.

By the way, this was when I changed the gemfile to include 'pg' under production (and of course, put sqlite under development and test) and then trying to run bundle install --without production.

提前感谢您的帮助！

推荐答案

如果您使用的是Windows，则可以在Rubyinstaller的文档中找到有关安装DevKit的详细说明:

If you are on Windows, then detailed instructions on installing DevKit can be found here in docs of Rubyinstaller:

https://github.com/oneclick/rubyinstaller/wiki/development-kit

按照这些说明进行操作后，便可以构建本机扩展.

After following these instructions native extensions will be able to build.

UPD :但奇怪的是，据其网站显示，Windows的Railsinstaller似乎已包含DevKit.可能您只需要执行该指令中的步骤4，即可确保已设置PATH.

UPD: but strange, seems like Railsinstaller for Windows already includes DevKit, according to its website. Probably you only need to do step 4 from that instruction to ensure that PATH is set.

如果我弄错了，并且您使用的是Mac，那么此答案应该会对您有所帮助.

If I'm mistaken and you are on Mac, then this answer should help you.

如果您使用的是Linux，则可能应该只从软件包管理器中安装了build-essential.

If you were on Linux, you should probably only have installed build-essential from your package manager.
