问题 Here's my code: var concat = require('concat-stream'); process.stdin.pipe(concat(function(){console.log("output")})); What I'm expecting this to do is output "output" every time I enter input into the console, but this doesn't work. Does anyone have an idea why this isn't working? If I do a fs.createReadStream() buffer, it works fine, just not with process.stdin.pipe(). I've used process.stdin.pipe() for other things though, and they worked fine. Thanks in advance! 回答1: The reason you get no

问题 This question already has answers here : About closure, LexicalEnvironment and GC (3 answers) Closed 1 year ago . Consider the following example: function makeFunction() { let x = 3; let s = "giant string, 100 MB in size"; return () => { console.log(x); }; } // Are both x and s held in memory here // or only x, because only x was referred to by the closure returned // from makeFunction? let made = makeFunction(); // Suppose there are no further usages of makeFunction after this point // Let's

问题 I know that I can use copy() function on the console to add content to the clipboard. When I am on any other page copy('test') works. When I am on youtube I get: Uncaught TypeError: copy is not a function How can I fix this. E.g. Is there a way to prevent a site from overriding specific functions using devtools? Strangely on firefox copy() works on youtube, so could this be a chrome bug? 回答1: Run this in console: document.querySelector('#copy').remove(); Then use copy() as normal, e.g. copy

问题 I'm experiencing an issue with running an opencv program in Xcode. I keep getting this error: https://i.stack.imgur.com/F6Gpu.png . Xcode works with other opencv programs, so I have no idea what would be causing this issue & how I would go about fixing it. Any and all help would be greatly appreciated. 回答1: My solution was to delete /Application/Xcode.app as well as /Library/Developer and ~/Library/Developer and reinstall Xcode. Edit: The error reappeared. Not sure why. I had the Xcode-Beta

问题 Is there a reason why you would want to set the Layout property to null in a _Layout.cshtml? For example, like this, before rendering the body view? ... <section id="content"> @{ Layout = null; } @RenderBody() </section> ... It seems pretty nonsensical to me, and removing the line setting Layout doesn't change the way page loads work observationally. Is there any reason why you would want to set the Layout property in _Layout.cshtml? 回答1: Layout pages can have a layout too. In nested layouts
