这是我在尝试使用 bin/bundle install 命令时遇到的错误

LJ$ bin/bundle install --without production

[!] There was an error parsing `Gemfile`: syntax error, unexpected tIDENTIFIER, expecting end-of-input - gem 'sass-rails', ‘~> 5.0’
     ^. Bundler cannot continue.

**我无法弄清楚问题所在。如果有帮助，我将与 Rails 速成课程书一起学习。

【问题讨论】：

你有一堆无效的引号字符（'和'）。这些需要替换为普通的单引号或双引号（' 或 "）。
你能说得更具体一些吗...比如哪个是无效的引号字符？
我确实在评论中告诉过你：'和'
幸运的是其他人帮助了我，因为您的答案不正确。我猜你不是很了解 Rails……太糟糕了。

【解决方案1】：

无效引号字符的一个例子是：

gem 'sqlite3’

第二个 ' 是无效的单引号。请注意它在您的示例代码中是如何轻微弯曲的。

当您在 TextEdit 等文本编辑器中编辑文本时，通常会出现这些类型的错误。尝试使用不同的文本编辑器修复单引号。尝试使用 TextWrangler、SublimeText 或 nano。
