ruby-on-rails - 未定义的方法 : Activate Bin Path

Question

几天前我对我的 bash 配置文件进行了一些编辑，然后去创建一个新的 Rails 应用程序，然后弹出了这个错误。我不太确定问题出在哪里，或者为什么没有正确路由，我想我已经解决了。我还包含了我的新 bash 配置文件和我的旧配置文件。我删除了旧的，因为它看起来像是在疯狂地重复自己。

我跑

$ rails new newapp

/usr/local/bin/rails:22:in `<main>': undefined method `activate_bin_path' for Gem:Module (NoMethodError)

哪个 gem

$ which gem
/Users/LMagnotti/.rvm/rubies/ruby-2.2.4/bin/gem

哪些 rails

 which rails
/usr/local/bin/rails

gem 环境

$ gem env

新的 Bash 配置文件

export PATH="/usr/local/bin:/usr/local/sbin:~/bin:$PATH"

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
PATH=$PATH:above/path/to/gems

source ~/.rvm/scripts/rvm

旧 Bash 配置文件

export PATH=/Users/LMagnotti/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/LMagnotti/.rvm/bin:/Lmagnotti/mongodb/bin:/Users/lmagnotti/mongodb/bin 

Answer 1

您的 PATH 分配中的 ~ 不会扩展。在这种情况下，您可以使用 ${HOME} 而不是 ~。

PATH 变量中的相对 above/path/to/gems 是怎么回事？您确定要这样做吗？

我怀疑其中之一导致了问题，或者实际上需要您从原始 PATH 表达式中删除的路径之一。
