在捆绑之前，确保` `gem install byebug '11.1.3‘--https://rubygems.org/’`‘-v成功

Question

我试图在visual studio代码上安装ruby的byebug gem，每次我尝试使用bundle install来安装它时，都会出现这个错误：

Errno::EACCES: Permission denied @ rb_sysopen -
/home/ja12tk/vendor/bundle/ruby/2.7.0/gems/byebug-11.1.3/CHANGELOG.md
An error occurred while installing byebug (11.1.3), and Bundler cannot continue.
Make sure that `gem install byebug -v '11.1.3' --source 'https://rubygems.org/'` succeeds
before bundling.

这就是Gemfile所说的：

source "https://rubygems.org"

gem "byebug"
gem "rspec", "~> 3.2.0"

以及Gemfile.lock

GEM
  remote: https://rubygems.org/
  specs:
    byebug (11.1.3)
    diff-lcs (1.4.4)

    rspec-support (3.2.2)

PLATFORMS
  ruby

DEPENDENCIES
  byebug
  rspec (~> 3.2.0)

BUNDLED WITH
   2.1.4

我甚至尝试过使用"gem install byebug“，它给出了这个错误：

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/2.7.0 directory.

任何帮助都将不胜感激

我也遇到过同样的问题，但我是这样解决的

我跑了

• sudo apt-get在根终端上安装ruby-dev
• 然后，包在所需的Gemfile目录下安装

就这样
