【问题描述】：

我正在尝试在我的 MacOS 上设置 Rails，但每当尝试运行 rails -v、rails new app 或 bundle exec rails server 等任何命令时都会遇到此错误。我使用

设置了导轨

gem install rails -v 6.1.3.2

`Could not find 'activesupport' (= 6.1.4.1) among 90 total gem(s) (Gem::MissingSpecError)
Checked in 'GEM_PATH=/Users/sam/.rvm/gems/ruby-2.6.5:/Users/sam/.rvm/rubies/ruby-2.6.5/lib/ruby/gems/2.6.0' at: /Users/sam/.rvm/gems/ruby-2.6.5/specifications/railties-6.1.4.1.gemspec, execute `gem env` for more information`

.zshrc 文件有这个：

export ANDROID_SDK=/Users/sam/Library/Android/sdk
export PATH=/Users/sam/Library/Android/sdk/platform-tools:$PATH
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

.bash_profile

export ANDROID_HOME=/Users/sam/Library/Android/sdk
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH


[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

export PATH="$HOME/.rbenv/bin:$PATH"
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
eval "$(rbenv init -)"
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
eval "$(rbenv init -)"

【解决方案1】：

可能有多个版本的 Rails 设置，因为您尝试使用 rbenv 进行设置，并且错误路径指向由 rvm 安装的 rails。尝试运行以下内容：

\curl -sSL https://get.rvm.io | bash -s stable --rails
cd 进入你的项目目录，bundle i
确保 ruby gem 与您安装的版本匹配，ruby --version
