我有一个我们称之为mygem
的gem,它有一个可执行文件用作CLI工具。
文件mygem/bin/mygem
:
#!/usr/bin/env ruby
lib = File.expand_path('../lib', __FILE__)
$LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib)
require 'bundler/setup'
....code goes here....
mygem.gemspec
:
Gem::Specification.new do |gem|
gem.bindir = 'bin'
gem.executables = ['mygem']
end
构建并安装:
gem build mygem.gemspec
gem install mygem-0.1.0.gem
<optionally bundle install, but that won't fix the error>
最后,我可以从命令行成功调用mygem
并运行脚本。
问题是它只能从不包含Gemfile
的文件夹中运行。否则,系统会输出错误:
WARN: Unresolved specs during Gem::Specification.reset:
json (>= 0)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
Could not find differ-0.1.2 in any of the sources
Run `bundle install` to install missing gems.
此错误消息中显示的实际gem会因当前目录中的Gemfile而异。
运行bundle exec mygem
会抑制部分错误消息,但除非在其他应用程序的Gemfile上运行bundle install
,否则仍无法执行:
Could not find differ-0.1.2 in any of the sources
Run `bundle install` to install missing gems.
如何解决这个问题?
答案 0 :(得分:0)
错误看起来非常典型。它说它无法在你的gemfile中找到gem,它会加载你的依赖项。通常bundle install会将它们添加到所有没有问题的地方,但我之前遇到过这样的问题,并且必须手动将条目放入gemfile中。
如果你是一个例子,请尝试添加到gemfile:
gem 'differ'
