无法创建 ROR 项目

Question

无法使用

在 rails 项目上创建 Ruby

sudo rails new name_of_your_new_app

出现如下错误：

  run  bundle install

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.

请告诉我这个问题的解决方案。

Answer 1

不要使用 sudo。仅遵循命令。

 rails new name_of_your_new_app

要运行这个命令，需要安装rails。安装 rails 运行

 gem install rails

Answer 2

使用 gem install byebug -v '4.0.2' 在您的终端上安装 byebug，然后再次运行捆绑安装。确保它首先成功完成。如果您想要一个新的 rails 应用程序，只需输入 rails new name-of-your-app 即可。无需使用 sudo。

Answer 3

我安装了 RVM 和 RBENV。首先我卸载了两者。之后我按照下面的命令安装了 ruby 和 rails

brew install ruby
gem install rails

现在工作正常。
