安装包时返回(从日志中的第 117 行开始):
Installing nio4r 1.2.1 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
因此无法安装捆绑包。它在最后返回:
An error occurred while installing nio4r (1.2.1), and Bundler cannot continue.
Make sure that `gem install nio4r -v '1.2.1'` succeeds before bundling.
注意:我已经尝试过其他问题的解决方案,但还是一样。 如果可以手动安装“nio4r”,请告诉我如何。
【问题讨论】:
-
gem install nio4r -v '1.2.1' run and/它会解决你的错误
-
它返回这个:pastebin.com/czfiV0Gb

提问时,请始终将错误完整日志直接包含在问题中。请不要链接到外部粘贴站点,因为那里的日志往往会很快消失,从而使问题在未来变得不那么有用。
