rbenv: ruby​​: 命令未找到 [英] rbenv: ruby: command not found

问题描述

我在本地目录上使用 rbenv 和 ruby​​ 版本 1.9.1-p378.

I am using rbenv with ruby version 1.9.1-p378 on the local dir.

命令 ruby -v 给出以下错误:

Command ruby -v gives the following error:

rbenv: ruby: command not found

The `ruby' command exists in these Ruby versions:
2.0.0-p353

知道为什么会这样吗?bundle、rails 命令也不起作用.

Any clue why this happens? The bundle, rails commands do not work either.

命令rbenv 版本:

* 1.9.1-p378 (set by /home/user/Desktop/r1/noko1/.ruby-version)
2.0.0-p353

推荐答案

1. 您收到的投诉来自rbenv.它抱怨的事实表明 rbenv 已设置并正常工作.

1. The complaint you get comes from rbenv. The fact that it's complaining shows that rbenv is set up and working.

找出运行该项目所需的 Ruby 版本.项目的根目录中带有 .ruby-version 文件，或者项目中的某个人知道并推荐使用该版本.

Figure out what version of Ruby is needed to run the project. Either the project comes with a .ruby-version file in the root, or someone on the project will know and recommend that version to use.

如果 .ruby-version 文件中未指定版本，请在项目目录中创建 .ruby-version 文件.

If the version is not specified in a .ruby-version file, create the .ruby-version file in the project directory.

在该目录中输入 ruby -v .可以吗?然后您安装了与您的 .ruby-version 要求相匹配的 Ruby 版本.

type ruby -v while in that directory. Is it OK? Then you have the version of Ruby installed that matches what your .ruby-version is asking for.

如果最后一个命令不正确，则输入 rbenv install.

If the last command was not OK, then type rbenv install.

既然已经安装了 Ruby，您需要运行您的程序.我假设它带有一个 Rakefile.

Now that Ruby is installed, you need to run your program. I'm assuming it comes with a Rakefile.

1. 安装打包工具:gem install bundler.

安装项目的依赖:bundle install

使用它指定的库的确切版本运行您的项目:bundle exec rails server

run your project using the exact versions of libraries it specifies: bundle exec rails server
