当我尝试安装mysql gem时,它显示无法构建gem本机扩展错误,这是为什么?我的mysql版本是5.1.36(WampServer)

如果你在 Linux 中遇到同样的问题,基本上你只需要先安装一些库。这对我有用。

> sudo apt-get install libmysql-ruby libmysqlclient-dev

> gem install mysql

If you are having this same problem in Linux, basically you just need to install a few libraries first. This worked for me.

> sudo apt-get install libmysql-ruby libmysqlclient-dev

> gem install mysql

由于这个问题不断出现在谷歌搜索结果中,我应该指出这个答案是大约两年前的。这是更新的答案: 如何在 Windows 7 上的 Rails 3 应用程序中使用“mysql2”gem?


据开发人员称,已经报告了一个错误,他正在努力将 mysql2 转移到 Windows。截至目前 - 仍在进行中。现在使用较旧的 mysql 驱动程序 - 或使用 sqlite 进行本地开发。

这是来自 googlegroups 的讨论

块引用
嘿埃尔万,
mysql2 问题跟踪器上已经有一张支持 Win32 的票证
http://github.com/brianmario/mysql2/issues#issue/8。您可以关注
它是为了进步;我正在尽力让事情顺利进行
你们。坚持住! :)


Since this keeps coming up on google as on of the top results, I should point out that this answers is from almost 2 years ago. Here is a more updated answer: How to use "mysql2" gem in Rails 3 application on Windows 7?


According to the developer there is a already a reported bug for it and he is working on parting mysql2 over to Windows. As of now - it's still in the works. Use the older mysql driver for now - or use sqlite for local development.

This is from the googlegroups discussion

Blockquote
Hey Erwann,
There's a ticket on the mysql2 issue tracker for Win32 support already
at http://github.com/brianmario/mysql2/issues#issue/8 . You can follow
it for progress; I'm doing my best to get things working smoothly for
you guys. Hang tight! :)

仅供记录:问题应该解决!

mysql2 gem v.0.2.6 已发布,支持 win32。

gem install mysql2 现在可以正常工作了。

请参阅:http://github.com/brianmario/mysql2 /issues/issue/8#issue/8/comment/479748

Just for the record: The problem should be solved!

The mysql2 gem v.0.2.6 is out, having win32 support.

gem install mysql2 worked without problems now.

See: http://github.com/brianmario/mysql2/issues/issue/8#issue/8/comment/479748

有用,
c:> gem install mysql2 -- '--with-mysql-lib="C:\Prog
ram 文件\MySQL\MySQL 连接器 C 6.0.2\lib\opt" --with-mysql-include="C:\Progra
m Files\MySQL\MySQL Connector C 6.0.2\include"'

暂时增强 PATH 以包含 DevKit...

构建本机扩展。这可能需要一段时间...

已成功安装 mysql2-0.3.6

正在安装 mysql2-0.3.6 的 ri 文档...

封闭类客户端的类/模块“mMysql2”未知 正在

安装 mysql2-0.3.6 的 RDoc 文档...

封闭类客户端的类/模块“mMysql2”

注意:

I.如果你的mysql中没有lib和include目录,那么安装mysql连接器c

II.首先安装DevKit然后只有你可以安装mysql2。 Windows 中的插件
https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

it works,
c:> gem install mysql2 -- '--with-mysql-lib="C:\Prog

Temporarily enhancing PATH to include DevKit...

Note:

I. If there is no lib and include directory in your mysql then install mysql connector c

II. First install DevKit then only you can install mysql2 plugin in windows

你可以尝试

gem install mysql2 -v '0.0.00' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include

You can try

gem install mysql2 -v '0.0.00' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include

你是否正确安装了DevKit?如果有疑问,请交叉检查安装步骤 -
http://rorguide.blogspot.com /2011/03/installing-mysql2-gem-on-ruby-192-and.html

按照这些步骤后,我能够安装 mysql2 gem。

Have you installed the DevKit correctly? If doubt, cross check the steps of installation on -

I was able to install mysql2 gem after following these steps.

在 Cygwin 下,我必须确保不仅安装 libmysqlclient18,还安装 libmysqlclient-devel。然后“gem install mysql2”就顺利了。

当然,Cygwin 中还有一个 ruby​​-mysql2 包。

Under Cygwin, I had to be sure to install not just libmysqlclient18, but also libmysqlclient-devel. Then "gem install mysql2" went fine.

There is also, of course, a ruby-mysql2 package in Cygwin.

用于

gem install mysql

windows,直到 mysql2 正确为止。

use

gem install mysql

for windows, till mysql2 get it right.
