Rubyonrails Bundle 器：在使用 gem 进行Bundle 安装期间找不到带有可执行Bundle 包 (Gem：：GemNotFoundException) 的 gem bundler (>= 0.a)

我正在执行以下脚本:

gem install rdoc --no-document
gem install bundle
bundle

输出:

+ gem install rdoc --no-document
Successfully installed rdoc-6.1.1
1 gem installed
+ gem install bundle
Successfully installed bundle-0.0.1
Parsing documentation for bundle-0.0.1
Done installing documentation for bundle after 2 seconds

/usr/lib/ruby/2.5.0/rubygems.rb:289:in `find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)
    from /usr/lib/ruby/2.5.0/rubygems.rb:308:in `activate_bin_path'
    from /srv/myuser/.gem/ruby/2.5.0/bin/bundle:23:in `<main>'

我在路径中添加了/srv/myuser/.gem/ruby/2.5.0/bin个，这样我就可以安装gems了.

gem list显示已安装的gems.

ls -ltrah /srv/myuser/.gem/ruby/2.5.0/bin

我也try 过安装bundler，但也没用.

gem which bundle代表什么都没有.gem spec bundle正在展示它.

更新:我试图在运行bundle之前安装bundler，但在以下情况下出现了相同的问题:

bundle (0.0.1)
