在Mac上安装Rails时出错

Question

安装Rails并运行rails server以获取在RoR上运行的克隆存储库后，我看到：

  

此系统上当前未安装Rails。要获取最新版本，只需输入：

$ sudo gem install rails

     

然后您可以重新运行“rails”命令。

在此之前我安装了根据终端正确安装的Rails。 我运行的命令是sudo gem install rails -V。我得到了：

我哪里错了？我的机器上安装了Ruby 2.0.0。

Answer 1

你能告诉我们这回来了吗？

which rails

你应该看到这样的事情：

/Users/<user>/.rvm/gems/ruby-2.0.0-p247/bin

我假设您只需要使用rails的路径更新您的PATH。

确保在登录脚本末尾有这样的内容（bash_login等）：

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

这将确保rvm在您的路径中。

您是否必须使用sudo来安装rails？如果没有，我会尝试在没有sudo的情况下安装。

Answer 2

好吧，我自己解决了这个问题，尽管由于railsinstaller无法与Mavericks合作，因此很难实现。首先，我卸载了rvm和homebrew，我不小心删除了我的/ User / bin文件夹中的ruby文件夹，删除了默认的ruby包。

现在，我从ruby-lang下载源代码解压缩并执行了

./configure
make test
make install

正确安装了包。由于它是rvm，自制软件和macport冲突，我搬出了macport并使用brew来升级我的ruby安装并最终通过

下载rails

gem install rails

Answer 3

在Mac上安装rails之前安装xcode。
