错误:执行gem时...(Gem::FilePermissionError)

Question

我正在尝试将rbenv设置为与fastlane一起使用。我遵循here的说明。我已经安装了rbenv

rbenv install 2.3.1

然后更新了它，使版本指向：

rbenv local 2.3.1 => 2.3.1 (set by /Users/pepe/Development/test-ios/.ruby-version)

然后我尝试安装bundler：

gem install bundler，并得到以下错误：

ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

然后运行下面的命令：

rbenv which gem /Users/pernillau-ext/.rbenv/versions/2.3.1/bin/gem

which gem /Users/pernillau-ext/.rbenv/shims/gem

显然，rbenv指向一个gem的安装，该系统(Mac 10.116)附带了预安装的ruby和gem，它们安装在/Library/Ruby/ gems /2.0.0目录中。那么，我在这里错过了什么？为什么gem命令使用了错误的版本。

编辑：

我的bash_profile：export ANDROID_HOME=/Users/pepe/Library/Android/sdk export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home export GEM_PATH=/Users/pepe/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0 export PATH=$PATH:/Users/pernillau-ext/Library/Android/sdk/tools:/Users/pernillau-ext/Library/Android/sdk/platform-tools PATH="$(perl -e 'print join(":", grep { not $seen{$_}++ } split(/:/, $ENV{PATH}))')" eval "$(rbenv init -)"

试着在$PATH中移动一些东西。将rbenv移到$PATH的前面。

shell中的$PATH应该大致类似于(伪代码)：

{rbenv shims} : {rbenv bin} : {system paths}
