rbenv没有正确设置ruby版本

Question

我成功安装了rbenv，这看起来是正确的：

piousboxs-MacBook-Pro:lms piousbox$ cat .rbenv-version
1.8.7-p374
piousboxs-MacBook-Pro:lms piousbox$ ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374) [i686-darwin12.2.1]
piousboxs-MacBook-Pro:lms piousbox$ which ruby
/Users/piousbox/.rbenv/shims/ruby

但是当我运行bundle时，它会以某种方式使用系统ruby？

Installing tiny_tds (0.5.1)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

    /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
checking for iconv_open() in iconv.h... no
checking for iconv_open() in -liconv... yes
checking for sybfront.h... no
-----
freetds is missing.
-----
*** 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.

有人可以帮忙吗？

Answer 1

确保安装并选择要使用的Ruby版本; rbenv默认为系统一，即使您已使用rbenv install添加另一个。

要查看要使用哪个Ruby rbenv，只需运行rbenv version。

有关如何在不同上下文中设置Ruby版本的详细信息，请参阅rbenv local或rbenv global或rbenv shell。

Answer 2

Emil Sit，问题是不知何故freetds尝试使用系统ruby，即使rbenv配置正确。在构建原生扩展时会传递--ruby标志：

Gem files will remain installed in /Users/piousbox/.bundler/tmp/26769/gems/tiny_tds-0.5.1 for inspection.
Results logged to /Users/piousbox/.bundler/tmp/26769/gems/tiny_tds-0.5.1/ext/tiny_tds/gem_make.out

An error occurred while installing tiny_tds (0.5.1), and Bundler cannot continue.
Make sure that `gem install tiny_tds -v '0.5.1'` succeeds before bundling.

Answer 3

确保在使用rbenv rehash安装捆绑包后运行gem install bundler。

Answer 4

解决方案是从/ usr / local / bundle中删除系统提供的bundler，因为它已过时且运行不正常。使用我的新ruby（通过rbenv）和bundler（通过新的ruby），我能够正确编译所有内容。
