安装rbenv;

然后在~/的末尾加上eval "$(rbenv init -)"。Bash_profile(或~/.zshrc MacOS);

打开一个新终端，运行gem install ***将工作!

给用户$whoami在这些文件夹中创建一些东西

sudo chown -R user /Library/Ruby/Gems/2.0.0

sudo gem update --system
sudo gem install (gemfile)

错误:当执行gem…(Gem:: FilePermissionError) 你没有写/Library/Ruby/Gems/2.6.0的权限

(2022方案) 这里已经添加了问题的详细原因

问题概述->该问题与ruby访问有关，M1 MAC自带ruby。我们没有被允许为我们的目的使用它。相反，我们安装了一个单独的ruby实例，并将其用于我们的目的。

下面的步骤帮助我解决了这个问题，希望这可能会有所帮助

我们不需要用rvn或chruby安装ruby。 我的解决方案使用自制程序来安装ruby。

打开终端 使用自制程序安装ruby

安装ruby

[用于重新安装]brew重装ruby

使用下面的命令检查ruby的路径 这红宝石 它应该安装在下面的路径 /usr/bin/ruby 将ruby路径更改为用户路径

检查您的系统使用了哪个shell

echo $0

-zsh

对于zshrc

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >>~/.zshrc . bin:$PATH

在bash

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >>~/~/.bashrc . bin:$PATH

退出并重新启动终端 用步骤5改变路径后 再次检查ruby的路径(执行步骤3 -请确保路径如下所示)

/usr/local/opt/ruby/bin/ruby

[如果您不退出并启动终端，将显示步骤4路径]

这一步可能并不适用于所有人，如果你安装了正确的Cocoapods版本，可以跳过第10和11步

检查安装的pod的版本

豆荚,版本

使用下面的命令卸载特定版本的Cocoapods

如果安装的版本是1.11.0

卸载cocoapods 1.11.0

安装特定版本的Cocoapods 安装cocoapods 1.11.0 将路径更改为Project目录cd {Project目录的路径} 在项目目录中安装捆绑程序

包安装

执行pod安装

正在安装

正如bobbdelsol所指出的，rehash对我来说很管用:
