【问题描述】：

我目前正在阅读 Steven Foote 的一本关于学习编程的书。这本书目前正在讨论自动化，并详细介绍了如何使用 grunt。

我刚刚使用 npm install -g grunt-cli 成功安装了 grunt，但是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
[L3:C21] E031: Bad assignment.

Linting js/prompt.js ...ERROR
[L4:C33] W030: Expected an assignment or function call and instead saw an expression.
'accessed on: ' + currentTime = '</p>';

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 grunt 还很陌生，所以我不确定如何修复这些错误。任何帮助将不胜感激。

【参考方案1】：

你只是在prompt.js 中有一些错误的分配。在某些地方，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>';
