Question

我正在开发一个程序，该程序有助于在命令行上（在https://github.com/keithrbennett/rexe，Y = np.matrix(logdif)上）运行Ruby代码。

当我gem install rexe并cd到项目根目录，并尝试gem install不在Gemfile中的文件时，它失败：

require

但是，当我➜ rexe git:(master) ✗  rexe -r awesome_print -oa '"hello"' Traceback (most recent call last): 12: from /Users/kbennett/.rvm/gems/ruby-2.6.0/bin/ruby_executable_hooks:24:in `<main>' 11: from /Users/kbennett/.rvm/gems/ruby-2.6.0/bin/ruby_executable_hooks:24:in `eval' 10: from /Users/kbennett/.rvm/gems/ruby-2.6.0/bin/rexe:23:in `<main>' 9: from /Users/kbennett/.rvm/gems/ruby-2.6.0/bin/rexe:23:in `load' 8: from /Users/kbennett/work/rexe/exe/rexe:403:in `<top (required)>' 7: from /Users/kbennett/.rvm/gems/ruby-2.6.0/gems/bundler-2.0.1/lib/bundler.rb:313:in `with_clean_env' 6: from /Users/kbennett/.rvm/gems/ruby-2.6.0/gems/bundler-2.0.1/lib/bundler.rb:562:in `with_env' 5: from /Users/kbennett/.rvm/gems/ruby-2.6.0/gems/bundler-2.0.1/lib/bundler.rb:313:in `block in with_clean_env' 4: from /Users/kbennett/work/rexe/exe/rexe:403:in `block in <top (required)>' 3: from /Users/kbennett/work/rexe/exe/rexe:385:in `call' 2: from /Users/kbennett/work/rexe/exe/rexe:385:in `each' 1: from /Users/kbennett/work/rexe/exe/rexe:385:in `block in call' /Users/kbennett/work/rexe/exe/rexe:385:in `require': cannot load such file -- awesome_print (LoadError)时，它工作正常：

cd ~

我将代码包装在➜ ~  rexe -r awesome_print -oa '"hello"' "hello"%中，我认为应该解决这个问题。

我可以直接使用Ruby解释器，并且可以：

Bundler.with_clean_env

因此，我想Bundler做出了一个假设，即不允许加载非Gemfile列出的gem，这几乎总是合理的，但就我而言，程序应该能够加载任何gem，这是一个障碍。

我知道Bundler正在查找Gemfile [.lock]并执行其认为正确的操作，但是有什么解决办法吗？

不是一个完整的答案，只是一个方向：尝试在需要gem之前，将请求的gem的路径显式添加到$LOAD_PATH中。例如：

pry(main)> require "awesome_print"                                                                    
LoadError: cannot load such file -- awesome_print

但是然后

pry(main)> $LOAD_PATH << "<home>/.rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/awesome_print-1.8.0/lib/";
pry(main)> require "awesome_print"
=> true

Voila！问题是如何为宝石找到正确的路径，也许gem which可以帮助...

Bundler不允许在项目主目录中使用gem
