Answer : You have to import RouterTestingModule import { RouterTestingModule } from "@angular/router/testing"; imports: [ ... RouterTestingModule ... ] Add the following import imports: [ RouterModule.forRoot([]), ... ], I had this error for some time as well while testing, and none of these answers really helped me. What fixed it for me was importing both the RouterTestingModule and the HttpClientTestingModule. So essentially it would look like this in your whatever.component.spec.ts file. beforeEach(async(() => { TestBed.configureTestingModule({ declarations: [ProductComponent], imports: [RouterTestingModule, HttpClientTestingModule], }).compileComponents(); })); You can get the imports from import { RouterTestingModule } from "@angular/router/testing"; import { HttpClientTestingModule } from "@angular/common/http/testing"; I dont know if this is the best solution, but this worked for me....

Answer : I'm not sure what API level your trying to target, but if you can use API 23 specific stuff, you can add the following to your AppTheme styles.xml: <item name="android:statusBarColor">@color/colorPrimaryDark</item> <item name="android:windowLightStatusBar">true</item> when android:windowLightStatusBar is set to true, status bar text color will be able to be seen when the status bar color is white, and vice-versa when android:windowLightStatusBar is set to false, status bar text color will be designed to be seen when the status bar color is dark. Example: <!-- Base application theme. --> <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> <!-- Customize your theme here. --> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name=...

Answer : If the file is called configure.ac, do $> autoconf Depends: M4, Automake If you're not sure what to do, try $> cat readme They must mean that you use "autoconf" to generate an executable "configure" file. So the order is: $> autoconf $> ./configure $> make $> make install The failsafe for generating a configure script is autoreconf -i , which not only takes care of calling autoconf itself, but also a host of other tools that may be needed. It's just problem with permissions Run chmod +x ./configure Should work

Answer : 1) Using inline styles <div [style.color]="myDynamicColor"> 2) Use multiple CSS classes mapping to what you want and switch classes like: /* CSS */ .theme { /* any shared styles */ } .theme.blue { color: blue; } .theme.red { color: red; } /* Template */ <div class="theme" [ngClass]="{blue: isBlue, red: isRed}"> <div class="theme" [class.blue]="isBlue"> Code samples from: https://angular.io/cheatsheet More info on ngClass directive : https://angular.io/docs/ts/latest/api/common/index/NgClass-directive.html Just use standard CSS variables: Your global css (eg: styles.css) body { --my-var: #000 } In your component's css or whatever it is: span { color: var(--my-var) } Then you can change the value of the variable directly with TS/JS by setting inline style to html element: document.querySelector("body").style.cssText = "--my-var: #000"; Otherwise you...

Answer : You can animate the scroll by getting the top of the 'target element' and then calling animate on the body.. $('html, body').animate({ scrollTop: $("#target-element").offset().top }, 1000); modifying it to be something like this will help you achieve what you are after $('.panel-collapse').on('shown.bs.collapse', function (e) { var $panel = $(this).closest('.panel'); $('html,body').animate({ scrollTop: $panel.offset().top }, 500); }); source: http://www.abeautifulsite.net/smoothly-scroll-to-an-element-without-a-jquery-plugin-2/ complementary fiddle: https://jsfiddle.net/hjugdwbp/ Edit: 2018-05-25 Bootstrap 4 Example Using the accordion example at: https://getbootstrap.com/docs/4.0/components/collapse/#accordion-example I have modified the code to support cards. $('.collapse').on('shown.bs.collapse', function(e) { var $card = $(this).closest('.card...

Answer : The error message pops up when none of the schemas in your search_path can be found. Either it is misconfigured. What do you get for this? SHOW search_path; Or you deleted the public schema from your standard system database template1 . You may have been connected to the wrong database when you ran drop schema public cascade; As the name suggests, this is the template for creating new databases. Therefore, every new database starts out without the (default) schema public now - while your default search_path probably has 'public' in it. Just run (as superuser public or see mgojohn's answer): CREATE SCHEMA public; in the database template1 (or any other database where you need it). The advice with DROP SCHEMA ... CASCADE to destroy all objects in it quickly is otherwise valid. That advice can cause some trouble if you have an application user (like 'postgres') and run the DROP/CREATE commands as a different user. This would happen ...

Answer : To enable root access: Pick an emulator system image that is NOT labelled "Google Play". (The label text and other UI details vary by Android Studio version.) Exception: As of 2020-10-08, the Release R "Android TV" system image will not run as root. Workaround: Use the Release Q (API level 29) Android TV system image instead. Test it: Launch the emulator, then run adb root . It should say restarting adbd as root or adbd is already running as root not adbd cannot run as root in production builds Alternate test: Run adb shell , and if the prompt ends with $ , run su . It should show a # prompt. Steps: To install and use an emulator image that can run as root: In Android Studio, use the menu command Tools > AVD Manager . Click the + Create Virtual Device... button. Select the virtual Hardware, and click Next . Select a System Image. Pick any image that does NOT say "(Google Play)" in the Target column. If you dep...

Answer : The accepted answer is wrong. From https://en.wikipedia.org/wiki/Unix_signal SIGTERM The SIGTERM signal is sent to a process to request its termination... SIGINT is nearly identical to SIGTERM. The description around command kill is incorrect. You can catch both of them and still be able to close the process with a SIGKILL - kill -9 pid That's wrong. Again, from above wiki: The SIGKILL signal is sent to a process to cause it to terminate immediately (kill). In contrast to SIGTERM and SIGINT, this signal cannot be caught or ignored, and the receiving process cannot perform any clean-up upon receiving this signal. So, all in all, SIGINT is nearly identical to SIGTERM . From https://en.wikipedia.org/wiki/Unix_signal: SIGINT is generated by the user pressing Ctrl + C and is an interrupt SIGTERM is a signal that is sent to request the process terminates. The kill command sends a SIGTERM and it's a terminate You can catc...
