Answer : You may have jQuery or Bootstrap included twice. I don't use React, but I was having the same problem with Angular. It turns out that I was including jQuery/Bootstrap in my index.html as well my "scripts" configuration (which I think would be your "entry"). You should import this line and Test again : import 'bootstrap/dist/js/bootstrap.bundle'; this work for me like a charm :) I got the same issue. I noticed that when i was using bootstrap.min.js and jquery.min.js at a same time. Then my dropdown takes two click for toggle in first time after page load. Then i commented bootstrap.min.js . Now it is not giving me this issue. Try this. Maybe it will solve your problem.

Answer : I think there are two questions here. What is the difference between throw and throw e; ? I don't think there is ever a good reason to write catch (Exception e) { throw e; } . This loses the original stacktrace. When you use throw; the original stacktrace is preserved. This is good because it means that the cause of the error is easier to find. What is the difference between catch and catch (Exception e) ? Both of your examples are the same and equally useless - they just catch an exception and then rethrow it. One minor difference is that the first example will generate a compiler warning. The variable 'e' is declared but never used It makes more sense to ask this question if you had some other code in your catch block that actually does something useful. For example you might want to log the exception: try { int value = 1 / int.Parse("0"); } catch (Exception e) { LogException(e); throw; } Now it's necessary ...

Answer : Analysis The WineHQ repository misses the dependencies for wine-stable package. I have reported a bug 48513 to WineHQ bugzilla. The main problem here is bad documentation, which is written in non-reproducible way. The Rosanne DiMesio's main idea is "People who don't bother to read the directions are always going to have problems.". So we need to write our own documentation until WineHQ-officials become smarter. The problem with dependencies was caused by the FAudio dependency, which is not contained in Debian/Ubuntu and WineHQ repositories. We can determine the exact package name by using command below and analyzing of their output: $ sudo apt-get install wine-stable-amd64 Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not y...
