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.

**我无法弄清问题是什么。如果有帮助的话，我会参加Rails Crash Course一书。

Answer 1

无效引号字符的示例是：

gem 'sqlite3’

第二个'是无效的单引号。请注意它在示例代码中稍微如何弯曲。

当您在TextEdit等文本编辑器中编辑文本时，通常会显示这些类型的错误。尝试使用其他文本编辑器修复单引号。尝试使用像TextWrangler，SublimeText或nano这样的东西。
