rubygems - OSX El Capitan，gem install “错误：执行 gem 时 ...（Errno::EINVAL）无效参数”

Question

任何 gem（例如 bundler、cocoapods）的 gem install 都会失败。

$ gem install bundler ERROR: While executing gem ... (Errno::EINVAL) Invalid argument

背景

在运行 OSX El Capitan v10.11.6 (15G31) 的新 macbook（2015 年中）上，我开始为开发工作设置它并安装了 xcode8、brew 和 ruby​​。我的gem env：

$ gem env
RubyGems Environment:

一些现有的帖子：

许多现有的帖子都集中在另一个与 El Capitan 中的“无根”安全功能相关的类似错误上：

ERROR: While executing gem ... (Errno::EPERM) Operation not permitted

一些 Errno::EPERM 相关帖子：1：CocoaPods 问题 3680，2：Stackoverflow Windows7，3： Bundler 问题 4065

什么不起作用：

gem install变种

$ sudo gem install bundler -n /usr/local/bin -V

将 $GEM_HOME 设置为 /usr/local/bin 和 ~/.gems。

echo $GEM_HOME /usr/local/bin echo $GEM_HOME ~/.gems

“无根”禁用

sudo nvram boot-args="rootless=0"; sudo reboot

Answer 1

似乎 ruby​​gems 版本 2.5.1 有一些问题。我安装了 ruby​​gems 版本 2.4.5.1 附带的旧 ruby​​ 版本 2.2.5。

使用brew install ruby,brew uninstall ruby来解决问题 (Errno::EINVAL)。
