Ruby MacOS无法安装Jekyll Gem

我已经尝试了一切，试图安装杰基尔宝石。我卸载/重新安装了rbenv，安装了ruby 2.6.1，将其设置为全局，运行

xcode-select--install

大约1000次，运行

xcode-select--switch/Library/Developer/CommandLineTools

，以及

gem-update--system

以及其他各种堆栈溢出修复程序。这些都不起作用。每次我都会收到这样一条熟悉的错误消息：

不确定为什么我的$PATH中有这么多重复项，但可能是因为我的bash_配置文件。

看起来您的路径设置加载的是系统ruby，而不是rbenv ruby

尝试从.bash_配置文件中删除这一行，因为您不想使用system ruby，而是使用RBENV的版本

/usr/local/opt/ruby/bin

如果这不起作用，我不知道为什么路径中会有如此多的重复项，可能是多次尝试使用RBENV造成的

我建议首先重新安装RBENV。您首先需要执行以下操作：

grep rbenv ~/.bashrc ~/.bash_profile ~/.zshrc /etc/profile /etc/profile.d/*

删除可能包含RBENV的文件中与RBENV相关的所有行

移除rbenv

rm -rf ~/.rbenv 

如果使用自制软件安装rbenv，则

brew uninstall rbenv

然后

brew doctor

，查看是否报告了其他问题

关闭所有正在运行的终端，然后打开一个新的终端。然后再次检查

gem env

，您应该会看到一个更干净的状态，与RBENV无关，只有您的系统ruby

或者，如果您愿意，您可以先尝试RVM，这样做，请参见

之后您可能需要重新启动终端，然后转到中间人项目文件夹并运行

bundle install

---

请发布

gem env

的输出以及您使用的MacOS版本？我在编辑中添加了它们。您建议使用RVM而不是rbenv的原因是什么？难道我不能尝试编辑指向rbenv ruby的路径吗？我将路径中的

/usr/local/opt/ruby

更改为

~/.rbenv/versions/2.6.1

，gem安装现在成功运行！我会将您的答案标记为正确，但您可能需要编辑它。@成吉思汗我更新了我的答案，很高兴它为您指出了正确的方向并使其正常工作。但您可能不想在配置文件中特别选择版本，让RBENV来选择
