Gem 파일이 설치된 위치를 찾는 방법

Gem 파일이 설치된 위치를 찾는 방법

다음을 사용하여 설치된 보석을 찾을 수 있습니다.gem list보석이 어디에 설치되어 있는지는 표시되지 않습니다.

보석을 설치하기 전에 보석이 어디에 있는지 어떻게 알 수 있습니까?

사용자의 보석 환경에 대해 알아봅니다.

다음을 사용하여 라이브러리 파일의 위치를 가져오는 것이 유용하다는 것을 알게 되었습니다.

gem which *gemname*

보석을 설치한 후 특정 보석이 어디에 있는지 알고 싶다면,입력해 보십시오.

 gem list

설치한 보석 목록을 볼 수 있습니다.지금 사용bundle show경로를 알고 싶은 보석의 이름을 대보세요.

 bundle show <gemName>

또는 (이전 버전의 번들러 기준):

 bundle info <gemName>

다른 답변을 완료하기 위해 보석 경로 보석은 특정 보석의 설치 경로를 찾을 수 있습니다.

설치:

gem install gem-path

용도:

gem path rails
=> /home/cbliard/.rvm/gems/ruby-2.1.5/gems/rails-4.0.13
gem path rails '< 4'
=> /home/cbliard/.rvm/gems/ruby-2.1.5/gems/rails-3.2.21

이 기능은 파일을 grep 또는 편집하는 데 사용할 수 있으므로 매우 유용합니다.

grep -R 'Internal server error' "$(gem path thin)"
subl "$(gem path thin)"

  Summary:
    Display information about the RubyGems environment

  Description:
    The RubyGems environment can be controlled through command line arguments,
    gemrc files, environment variables and built-in defaults.

    Command line argument defaults and some RubyGems defaults can be set in a
    ~/.gemrc file for individual users and a /etc/gemrc for all users. These
    files are YAML files with the following YAML keys:

      :sources: A YAML array of remote gem repositories to install gems from
      :verbose: Verbosity of the gem command. false, true, and :really are the
                levels
      :update_sources: Enable/disable automatic updating of repository metadata
      :backtrace: Print backtrace when RubyGems encounters an error
      :gempath: The paths in which to look for gems
      :disable_default_gem_server: Force specification of gem server host on
    push
      <gem_command>: A string containing arguments for the specified gem command

    Example:

      :verbose: false
      install: --no-wrappers
      update: --no-wrappers
      :disable_default_gem_server: true

    RubyGems' default local repository can be overridden with the GEM_PATH and
    GEM_HOME environment variables. GEM_HOME sets the default repository to
    install into. GEM_PATH allows multiple local repositories to be searched for
    gems.

    If you are behind a proxy server, RubyGems uses the HTTP_PROXY,
    HTTP_PROXY_USER and HTTP_PROXY_PASS environment variables to discover the
    proxy server.

    If you would like to push gems to a private gem server the RUBYGEMS_HOST
    environment variable can be set to the URI for that server.

    If you are packaging RubyGems all of RubyGems' defaults are in
    lib/rubygems/defaults.rb.  You may override these in
    lib/rubygems/defaults/operating_system.rb

속일 수 있습니다gem open보석 경로를 표시합니다.

VISUAL=echo gem open gem-name

예:

VISUAL=echo gem open rails
=> /usr/local/opt/asdf/installs/ruby/2.4.3/lib/ruby/gems/2.4.0/gems/rails-5.1.4

그것은 단지 효과가 있을 뿐이며, 제3자 보석은 필요하지 않습니다.

gem env와 똑같이 작동합니다.gem environment타이핑을 저장합니다.

그gem env에는 보석을 설치할 수 있는 위치가 나열되어 있지만 이 위치는 10개 이상일 수 있습니다.특정 보석이 설치된 위치를 알고 싶다면 다음을 실행할 수 있습니다.

gem list -d <gemname>

rvm 도구를 사용하는 경우 다음 명령을 실행하여 gem 경로를 인쇄할 수 있습니다.

rvm gemdir

OR

echo $GEM_HOME

이것은 작동하며 각 보석의 경로에 설치된 를 제공합니다.이는 다단계 도커 빌드를 시도할 때 매우 유용합니다.특정 디렉토리에서 번들 후 설치를 복사할 수 있습니다.
