Question

我的红宝石项目在其中一部Macbook上运行正常，但在另一本上却出现此错误：

Traceback (most recent call last):

我在各个方面都遇到了类似的问题，并且大多数修复都在代码中（某些require语句在彼此之间循环），但是该程序可以在我的另一台Macbook上运行，而没有这些错误。他们的存储库已同步，我什至尝试查看代码以确保它们相同。我还使用bundle list比较了宝石的版本和它们匹配的版本。这是gemfile，以备不时之需。

source "https://rubygems.org"

gem 'pry'
gem 'pry-rescue' 
gem 'pry-stack_explorer'
gem 'pry-nav'
gem 'poltergeist'
gem 'nokogiri'
gem 'rspec'
gem 'require_all'

两台Macbook都运行相同版本的Mojave，我不认为会导致这种情况的系统有所不同。它们应该都在同一版本的宝石和捆绑器等上。

有什么想法吗？

此行

/Users/TuzsNewMacBook/.rvm/gems/ruby-2.5.1/gems/cliver-0.3.2/lib/cliver/dependency.rb:143:in `raise_not_found!': Could not find an executable ["phantomjs"] on your path. (Cliver::Dependency::NotFound)

解释为什么您的项目无法在另一台计算机上运行。

Gem poltergeist是Capybara的PhantomJS驱动程序。要使其正常工作，您需要安装phantomjs（无头浏览器）。您可以从PhantomJS官方网站下载它：

http://phantomjs.org/download.html

确保安装相同版本。为此，请在第一台Macbook终端中运行以下命令：

phantomjs -v

查找已安装的版本，然后在第二台Macbook上安装相同的版本。

专案可在一台电脑上运作，但无法在其他电脑上运作
