创建Ruby on rails项目

sudo rails new name_of_your_new_app

获取如下错误：

  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.

请让我知道这个问题的解决方案。

Answer 1

不要使用sudo。只有以下命令。

 rails new name_of_your_new_app

要运行此命令，您需要安装rails。要安装rails run

 gem install rails

Answer 2

使用gem install byebug -v '4.0.2'在终端上安装byebug，然后再次运行bundle install。确保它首先成功完成。如果你想要一个新的rails应用程序，只需输入rails new name-of-your-app即可。不需要使用sudo。

Answer 3

我安装了RVM和RBENV。首先我卸载了两个。之后我按照命令

安装了ruby和rails

brew install ruby
gem install rails

现在工作正常。
