Question

我目前正在读Steven Foote的“学习编程”一书。这本书目前正在讨论自动化，并详细介绍了如何使用grunt。

我刚刚成功使用npm install -g grunt-cli安装了grunt，但我现在遇到了一个我不熟悉的错误。

当我运行grunt时，我收到以下错误：

users-mbp:kittenbook user$ grunt
Running "jshint:files" (jshint) task
Linting js/prompt.js ...ERROR

Warning: Task "jshint:files" failed. Use --force to continue.

prompt.js包含：

var userName = prompt('Hello what\'s your name?');
document.body.innerHTML = '<h1>Hello, ' + userName + '!</h1>' +
  '<p>' + projectName = ' ' _ versionNumber +
  'accessed on: ' + currentTime = '</p>';

我对咕噜很新，所以我不知道如何解决错误。任何帮助将不胜感激。

Answer 1

prompt.js中只有一些错误的分配。在一些地方，您使用=而不是+来连接字符串。

替换为以下内容：

var userName = prompt('Hello what\'s your name?');
document.body.innerHTML = '<h1>Hello, ' + userName + '!</h1>' +
'<p>' + projectName + ' ' + versionNumber +
'accessed on: ' + currentTime + '</p>';

试图运行咕噜声，但得到错误，不知道如何解决它们
