尝试运行 Grunt 但遇到错误并且不确定如何修复它们

Question

我目前正在阅读 Steven Foote 的一本关于学习编程的书。该书目前正在谈论自动化，并且正在详细说明如何使用 g运行t.

我刚刚成功地使用 npm install -g grunt-cli 安装了 g运行t，但是我现在运行遇到了一个我不熟悉的错误。

当我运行 g运行t 我得到以下错误：

users-mbp:kittenbook user$ grunt
Running "jshint:files" (jshint) task
Linting js/prompt.js ...ERROR
[L3:C21] E031: Bad assignment.

'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>';

我是 g运行t 的新手，所以我不确定如何修复这些错误。任何帮助将不胜感激。

Answer 1

您只是在 prompt.js 中有一些错误的分配。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>';
