问题 So PHPstorm is running the php code fine in its console when I click run, that's great but I want to see it in the browser. So I created a new PHP web application inside PHPstorm, set up the server to "localhost:8000". Now when I click RUN it opens the browser but I get an error message: "Oops! Google Chrome could not connect to localhost:8000" What am I doing wrong?? Thanks! 回答1: You have to configure a run configuration for your project first. Go to Run -> Edit Configurations , click on

问题 A common problem with VM Java console output is that System.out and System.err are not usually synchronized properly, possibly because they are on different threads. This results in mixed up output such as the following: debugging output mixed up with runtime exception stack trace [8, 1, 3, 5, 9, 13, 15, 17, 19] Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 9 scanning xAnswer: 1 xValue: 1 total: 1 [1, 1, 0, 0, 0, 0, 0, 0, 0] at cra.common.Group_jsc.listSubsetSum(Group

问题 I am following this apple doc and trying to add provisioning profiles and signing identities for a new apple-id. The problem is that when I add a new apple-id in Xcode -> Settings -> Accounts I am getting "Error Fetching Developer Info". This is about all I have found searching around on google. I've restarted Xcode multiple times to no avail. Has anyone encountered this error? How do I fix this issue? 回答1: This is what worked for me. XCode > Preferences > Accounts Retype password, then click

问题 I've installed Android Studio 3.0, and have compiled and run applications successfully. Device File explorer pane has the above error message in red, and nothing else. 回答1: Each Android Studio project requires information as to what SDK is to be used, and where it is located. The overall configuration defined in the SDK Manager under the tools menu is not enough, and it is used seemly to download and install the necessary SDK, so make sure you have Android SDK installed. Now opened or create

问题 this is my first time using an IDE. I was wondering if its possible, as I've done in vim with imap, to make it so that when I press tab 4 spaces are produced in the editor. If this is possible, please point me how to do it. I'm not super familiar with key symbols so please be as explicit a possible; I poked around the keymap under settings but it was pretty confusing. 回答1: You can customize the Tab size in Pycharm. Goto Preference --> Editor --> Code Style --> Python. 来源： https:/

问题 NetBeans 6.5 with Python support provides the docstring documentation for a function/method in a popup when auto-completing, but is there another way to view docstrings? Perhaps achieved by mousing over a function/method name, or clicking somewhere? The best I can seem to do is "Go to source" in the right-click menu. 回答1: I received the following answer from Tor Norbye at Sun: Hold the ctrl key (or Cmd on Mac) and then hover. Also, Ctrl-Shift-Space (e.g. code completion + shift) will display

问题 I'm using IntelliJ IDEA 12 to develop a PHP web application using the CodeIgniter framework. Due to the way CI instantiates objects and methods, IDEA thinks they don't exist when they're called: As you can see, I get those annoying orange squigglies under every single CodeIgniter class/method I try to use. Here's the code for the CI_Controller class, giving some insight into how they're creating the objects: class CI_Controller { private static $instance; /** * Constructor */ public function

问题 One frustrating thing I find in Intellij's project view is that it shows all the classes in a file instead of just the class for which the file is named. The problem with this is that to open a file I have to double click twice: once to expand the file and show the classes in the file, and then a second time to actually open the file. In most cases I don't want to see the classes inside of a file. I just want to see the file in the project view and when I double click on the file I want to
