进入npm start我的Node项目目录后,我看到旋转管道符号显示npm正在加载.但是,此图形无限期显示,没有任何反应.没有提供错误消息.我该如何修复或至少诊断此问题？

我的package.json如下:

{
  "name": "Project_Name",
  "version": "0.0.1",
  "private": true,
  "main": "./bin/www",
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "express": "~4.2.0",
    "static-favicon": "~1.0.0",
    "morgan": "~1.0.0",
    "cookie-parser": "~1.0.1",
    "body-parser": "~1.0.0",
    "debug": "~0.7.4",
    "jade": "~1.3.0",
    "request": "~2.39.0",
    "oauth-1.0a": "~0.1.1",
    "passport": "~0.2.0",
    "express-session": "~1.7.2",
    "passport-local": "~1.0.0",
    "connect-flash": "~0.1.1"
  }
}

我怀疑缺少依赖可能是一个问题,但这似乎不是一个问题.我运行npm-install-missing模块并得到以下结果:

I'm using Parsley.js to validate my form. I tell Parsley to monitor the form by adding...

<form data-validate="parsley" name="myform"> 

And my elements look like:

<input type="text" name="username" data-required="true"/>

If you neglect the required fields and attempt to submit the form using this button...

<input type="submit" value="Submit"/> 

Parsley displays an error and does not allow the form to be submitted. However, if you use the following submit method instead...

<a href="#" onClick="document.myform.submit();"> Submit </a> 

Parlsey 只是忽略错误并提交表单。到底是怎么回事？Parsley 是否专门监听 input[type=submit] 元素而不是表单本身的提交？（我需要将“提交”功能设为链接，因为我想对其应用特殊样式。）

我'Float' is not convertible to 'UInt8'在Swift中使用以下公式时收到与类型相关的错误().虽然我看过有类似问题的帖子,但我似乎无法弄清楚为什么在这种情况下,首先会转换为UInt8以及如何修复类型转换错误.我是这门语言的新手.

func compoundInterest (principal p: Float, interestRate r: Float,
    timesCompounded n: Int, years t: Int) -> Float {
        return p * pow(1 + (r / n), n * t)
}

compoundInterest(principal: 150, interestRate: 0.05, timesCompounded: 2, years: 10)

我需要确定今天是否是本月的第三个星期四。使用 Python 实现此目的的有效方法是什么？
