我在express.js和coffeescript中创建了我的第一个应用程序。代码位于: https://github.com/findjashua/contactlist
当我尝试运行它时,我收到以下错误:
/Users/jashua/local/lib/node_modules/coffee-script/lib/coffee-script/helpers.js:216
codeLine = codeLine.slice(0, start) + colorize(codeLine.slice(start, end
^
TypeError: Cannot call method 'slice' of undefined

我假设它与contacts.coffee有关,但无法想到任何事情。有什么想法吗?
答案 0 :(得分:1)
你永远不会关闭new ContactModel(
的parens。
exports.addContact = (req, res) ->
contact = new ContactModel(
name: req.body.name
phone: req.body.phone
contact.save((err) ->
if not err
console.log('created')
res.send(contact)
else
res.send(error)
)
我的提示:忘记所有这些parens。关于coffeescript的一个好处是你可以使用缩进而不是像你的源代码中关闭的parens那样有大的浮动关闭分隔符链。只是做:
someFunction (arg1, arg2) ->
body of nested function
