亲爱的Stack Overflow读者,
我遇到了安装RubyGem的问题。我尝试了两种方法来安装它,但都失败了。
首先,我运行sudo command gem install github-pages
。
输出如下:
dhcp-128-189-232-78:Repos 7Ymr$ sudo gem install github-pages

ERROR: Error installing github-pages:

#> ^
然后,我也尝试从rubygems网站下载并安装。我下载了最新版本并运行install命令,但也有一些错误。
dhcp-128-189-232-78:downloads 7Ymr$ cd rubygems-2.6.13/
dhcp-128-189-232-78:rubygems-2.6.13 7Ymr$ ruby setup.rb
ERROR: While executing gem ... (Errno::EACCES)
Permission denied - /Library/Ruby/Site/2.0.0/rubygems
#> ^ ^
我在网上搜索了很长时间。但没用。请帮助或尝试提供一些如何实现这一点的想法。想知道最好的方法是什么?
提前致谢。

错误非常清楚。在第一种情况下,您的Ruby版本对于需要安装的液体版本来说太旧了。运行ruby --version
以查找系统默认使用的Ruby版本。您需要更新到Ruby 2.1.0或更高版本才能安装liquid
,这是您尝试安装的github-pages
gem的必需依赖项。
在第二种情况下,Ruby没有写入该文件夹的权限。 "许可被拒绝"错误几乎总是意味着您忘记使用管理权限运行命令。在这种情况下,您应该运行sudo ruby setup.rb
。
