QUESTION
I am currently setting up a boilerplate with React, Typescript, styled components, webpack etc. and I am getting an error when trying to run eslint:
Error: Must use import to load ES Module
Here is a more verbose version of the error:
...ANSWER
Answered 2022-Mar-15 at 16:08I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.
So, do this:
- In package.json, update the line
"babel-eslint": "^10.0.2",
to"@babel/eslint-parser": "^7.5.4",
. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3. - Run
npm i
from a terminal/command prompt in the folder - In .eslintrc, update the parser line
"parser": "babel-eslint",
to"parser": "@babel/eslint-parser",
- In .eslintrc, add
"requireConfigFile": false,
to the parserOptions section (underneath"ecmaVersion": 8,
) (I needed this or babel was looking for config files I don't have) - Run the command to lint a file
Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.
QUESTION
I have run my app but still Device Manager is saying
No emulators are currently running. To launch an emulator use the Device Manager or run your app while targeting a virtual device
As you can see a green dot in the emulator that means "Emulator is running"
And some time emulator is showed but when I click on screen then emulator gone
I think this version of the android studio has more bugs when compared to its previous version
Do you guys have any tricks or solutions?
Any help will be is always appreciated!
...ANSWER
Answered 2022-Feb-16 at 04:48I have 2 Solutions so you can try both if one doesn't work
Solution No 1Select device manager and select your device and select the drop-down menu
then click on the show on disk option
then delete all files that have the .lock
extension and run your emulator again.
You can get a normal emulator like previous time android studio have, so to get the previous emulator in the new version of android studio you can do these steps
open the settings tab by following the below steps or by pressing Ctrl + Alt + S
Select File > Settings > Tools > Emulator
then unTick the option name Launch in a Tool Window then click okay now you got the previous emulator. and if in the emulator you got any issues you can check This Solution for Emulator on StackOverFlow
QUESTION
I am trying to compile and load dynamically generated Java code during runtime. Since both ClassLoader::defineClass and Unsafe::defineAnonymousClass have serious drawbacks in this scenario, I tried using hidden classes via Lookup::defineHiddenClass instead. This works fine for all classes that I tried to load, except for those that call lambda expressions or contain anonymous classes.
Calling a lambda expression throws the following exception:
...ANSWER
Answered 2022-Feb-23 at 18:19You can not turn arbitrary classes into hidden classes.
The documentation of defineHiddenClass
contains the sentence
- On any attempt to resolve the entry in the run-time constant pool indicated by
this_class
, the symbolic reference is considered to be resolved toC
and resolution always succeeds immediately.
What it doesn’t spell out explicitly is that this is the only place where a type resolution ever ends up at the hidden class.
But it has been said unambiguously in bug report JDK-8222730:
For a hidden class, its specified hidden name should only be accessible through the hidden class's 'this_class' constant pool entry.
The class should not be accessible by specifying its original name in, for example, a method or field signature even within the hidden class.
Which we can check. Even a simple case like
QUESTION
[NOTE: I asked this question based on an older version of Rakudo. As explained in the accepted answer, the confusing output was the result of Rakudo bugs, which have now been resolved. I've left the original version of the Q below for historical reference.]
Raku sometimes prohibits re-binding; both of the following lines
...ANSWER
Answered 2021-Sep-22 at 00:26A decidedly non-authoritative answer. Curiously, like jnthn in your prior Q, it feels natural to answer your questions in reverse order:
Is there any way to tell Raku "don't rebind this name to a new value, no-really-I-mean-it"?
As far as I can tell so far -- purely by testing variations, not by checking roast or the compiler source -- you can and must declare a sigil free symbol, and it must not be one declared with my \symbol ...

QUESTION
I know that compiler is usually the last thing to blame for bugs in a code, but I do not see any other explanation for the following behaviour of the following C++ code (distilled down from an actual project):
...ANSWER
Answered 2022-Feb-01 at 15:49The evaluation order of A = B
was not specified before c++17, after c++17 B
is guaranteed to be evaluated before A
, see https://en.cppreference.com/w/cpp/language/eval_order rule 20.
The behaviour of valMap[val] = valMap.size();
is therefore unspecified in c++14, you should use:
QUESTION
Looking into UTF8 decoding performance, I noticed the performance of protobuf's UnsafeProcessor::decodeUtf8
is better than String(byte[] bytes, int offset, int length, Charset charset)
for the following non ascii string: "Quizdeltagerne spiste jordbær med flØde, mens cirkusklovnen"
.
I tried to figure out why, so I copied the relevant code in String
and replaced the array accesses with unsafe array accesses, same as UnsafeProcessor::decodeUtf8
.

QUESTION
After migrating from Remark to MDX, my builds on Netlify are failing.
I get this error when trying to build:
...ANSWER
Answered 2022-Jan-08 at 07:21The problem is that you have Node 17.2.0. locally but in Netlify's environment, you are running a lower version (by default it's not set as 17.2.0). So the local environment is OK, Netlify environment is KO because of this mismatch of Node versions.
When Netlify deploys your site it installs and builds again your site so you should ensure that both environments work under the same conditions. Otherwise, both node_modules
will differ so your application will have different behavior or eventually won't even build because of dependency errors.
You can easily play with the Node version in multiple ways but I'd recommend using the .nvmrc
file. Just run the following command in the root of your project:

I have an electron repo (https://github.com/MartinBarker/RenderTune) which used to work on windows 10 fine when ran with command prompt. After a couple months I come back on a new fresh windows 10 machine with an Nvidia GPU, and the electron app prints an error in the window when starting up:

Answered 2022-Jan-03 at 01:54You can try disabling hardware acceleration using app.disableHardwareAcceleration()
(See the docs). I don't think this is a fix though, it just makes the message go away for me.

QUESTION
iOS 15 leads to content being hidden under the address bar when the virtual keyboard is active. A bug report can be found here. To see the problem, run the snippet in full size on an iPhone with iOS 15 with the address bar on the bottom and press the input field. Alternatively check out this codepen
How can I show the input field when the keyboard is active? I've tried setting padding to safe-area-inset-bottom
with no luck.
