不会运行任何 rails 命令

Question

我正在尝试学习 rails 并且在过去几周没有使用它，但是今天当我尝试运行任何 rails 命令时，例如 -'导轨-v' - '脚本/服务器'

我没有重新安装 ruby​​，但不知道可能出了什么问题 我正在使用全新的 Macbook Pro

Jeremy-Geross-MacBook-Pro:~ Jeremy$ rails -v

哪里是 rails : /usr/bin/rails

Answer 1

看起来您的 gemrc 文件可能已损坏。您可以删除该文件（或最好将其移开）并查看内容。它应该是每行key: value 的形式，或者key: 后跟一些缩进的行。
