In my rails app, I get a syntax error somewhere in a huge js file that is presumably generated by webpacker. But it seems to be some sort of angular/material code. If I don't include material design, the error goes away, so it seems to be related to material design. This is the part that causes the syntax error:
function instantiateSupportedAnimationDriver() {
return !(function webpackMissingModule() { var e = new Error("Cannot find module '#angular/animations/browser'"); e.code = 'MODULE_NOT_FOUND'; throw e; }())() ? new !(function webpackMissingModule() { var e = new Error("Cannot find module '#angular/animations/browser'"); e.code = 'MODULE_NOT_FOUND'; throw e; }())() : new !(function webpackMissingModule() { var e = new Error("Cannot find module '#angular/animations/browser'"); e.code = 'MODULE_NOT_FOUND'; throw e; }())();
}
Note that telling me how to fix the syntax error doesn't help me. This code is not in my control and I wouldn't know how to effectively patch it. Besides, it's a frequently used piece of code, I doubt that it has a syntax error, probably something in plumbing is incorrect.
Some context: I probably don't get all the mechanics right. I am trying to make the combination Rails + Webpacker + Typescript + Angular + Material work. It's quite tricky, I find nothing useful on it on the web and I seem to be pretty much the first one to do it. I saw some suggestions to make an api-only rails app, but I don't like that...
I never really figured out why this caused a syntax error in a seemingly unrelated file, but I had some "unmet peer dependency" warnings and when I fixed them, this went away.

Okay so i was following a mern stack tutorial and the tutor wrote out some lines of code but didnt really explain them well. this is the code:
const path = require('path')
const {fileURLToPath} = require('url')
const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);
app.use("/assets", express.static(path.join(__dirname, "public/assets")));
Now Im not stupid or a bad programmer. even though i dont really have an explanation for what the code is doing, i have a pretty good idea. the problem is that when i run my database, i get this error:
SyntaxError: Identifier '__filename' has already been declared
which is crazy because i havent used '__filename' anywhere else in the code. when i try to change '__filename' to 'filename' then i get this error:
SyntaxError: Cannot use 'import.meta' outside a module
Im so confused. Please can someone just tell me what the code does and why i am getting these errors and also how to fix the errors.
check your package.json() if it is having a
"type":"module"
if it has then remove it
I was learning a bit about how Machine Learning works and eventually built a small C# application because of a tutorial I was watching where a model determines what species of Bee a particular bee IS. It works well in the C# application, but I was also developing an app project that had picture taking capabilities in mind so I thought "No reason the model I saved in the first project can't work in the second, right?". Apparently there is a reason why it can't work because here is the necessary code to view in the app project:
MLContext m_mlObj;
DataViewSchema m_modelSchema;
ITransformer m_loadedTrainedModel;
var folderPath = DependencyService.Get<IFileSystem>().GetExternalStorage();
var fileDir = Path.Combine(folderPath, "trainedModel.zip");
bool testValue = File.Exists(fileDir);
if(testValue)
{
Console.WriteLine("File in fact exists.");
try
{
m_loadedTrainedModel = m_mlObj.Model.Load(fileDir, out m_modelSchema);
}
catch (Exception e)
{
Console.WriteLine("\n\n\nInner exception: " + e.InnerException);
}
}
else
{
Console.WriteLine("File does not exist");
}
I have a breakpoint on the "m_loadedTrainedModel = m_mlObj.Model.Load(fileDir, out m_modelSchema);" line of course and it always triggers an exception.
The exception states:
---> System.TypeLoadException: Could not load type of field 'Microsoft.ML.Transforms.DnnRetrainTransformer:_tfInputShapes' (9) due to: Could not resolve type with token 01000060 from typeref (expected class 'Tensorflow.TensorShape' in assembly 'TensorFlow.NET, Version=0.20.1.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51') assembly:TensorFlow.NET, Version=0.20.1.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd5 1 type:Tensorflow.TensorShape member:(null)
What I THINK this means is it's checking for Tensorflow.TensorShape inside of the package TensorFlow.NET and isn't finding it. If that's the case, I believe I don't have the correct package installed so my Xamarin project will be able to load the model correctly, maybe? Or if not, then what may be the real underlying issue? The code seems straight forward so I'm a bit perplexed as to how this is failing.
If the solution is blatantly going over my head, my apologies and thank you to anyone who is willing to help.
When working with ML.NET on ARM, TensorFlow is one of the limitations at the time of this writing.

What you might want to consider in the meantime is deploying your model as a Web API and making requests to that API from your mobile app.

I'm trying to use the haskell-src-exts package to parse Haskell modules. Currently, I'm trying to parse the acme-io package's module, but I keep getting this error no matter what parse mode I try:
*** Exception: fromParseResult: Parse failed at [System/IO/Unsafe/Really/IMeanIt] (1:57): TemplateHaskell is not enabled
The module mentioned makes no references to TemplateHaskell, not in it's LANGUAGE pragma, nor is there a $ anywhere in the source file.
I'm wondering if my parse mode has something to do with it - here it is:
defaultParseMode { parseFilename = toFilePath m
, baseLanguage = Haskell2010
, extensions = []
, ignoreLanguagePragmas = True
, ignoreLinePragmas = True
, fixities = Nothing
}
I've also tried to replace the extensions field with knownExtensions from the parsing suite, without any luck.
This is a duplicate question of this answer - using the parseFile function fixed the issue. However, the reader should note that haskell-src-exts uses different parsing than GHC - I ran into another similar issue right after this, because haskell-src-exts can't handle multi-param contexts without -XMultiParamTypeClasses, yet GHC can, borking the parser if you're scraping Hackage. Hint may be a better option, can't say for sure though.
I've noticed that calling hh_client is not always returning correct result. For example: I have following pieces of code:
backend\ConvertMessage.hh:
<?hh // strict
namespace ApiBackend\ConvertMessage {
enum Status: int {
success = 0;
// ... error codes
};
// ... some other classes
};
other place in project:
throw new \SoapFault(
'Server',
\ApiBackend\ConvertMessage\Status::getNames()[$result->status]
);
Sometimes, after doing some changes in project I get following error message: Could not find static method getNames in type ApiBackend\ConvertMessage\Status (Typing[4090])
When I remove a semicolon after one of closing curly brackets, hh_client stops displaying error. But when I insert semicolon back on its place, typechecker still gives me No errors! message.
This is not the only file that causes this problem - it happens to all enums.
It seems to me that it is problem with some cache of either hh_client or hh_server.
Thanks in advance for helping me with solving this problem (and sorry if my english is not too good).
You are probably using an outdated version of HHVM. This problem sounds an awful lot like this race condition, which was fixed in HHVM 3.5.0 and newer (and was backported into the 3.3.3 LTS release). Notably, 3.4.x still had the bug.
What version of HHVM are you using?
I'm having problems with a specific line of code - building.transmitter:[operation](player, unpack({...})) that causes an error in Corona, yet this loads fine when it's run in Lua separately. I suspect it has something to do with the : being placed before the [operation] variable but I'm clueless why.
Specifically the module is written as,
local activate = {}
local function activate.transmitter(player, operation, ...)
building = player:getTile()
building.transmitter:[operation](player, unpack({...}))
end
return activate
The runtime errror that is appearing gives me
"error loading module from file, '<name>' expected near '['"
Edit - WOW! I didn't notice that when troubleshooting this in Corona I changed some of the lines of code to identify the problem. I then mistakenly tested the edited code in Lua and it ran fine. I didn't realize the code wasn't the original until siffiejoe pointed out the interpreter getting an error as well. Sorry for the mistake.
maybe Corona uses older version of Lua which does not support this syntax. You can try workaround instead of
building.transmitter:[operation](player, unpack({...}));
you can call
building.transmitter[operation](building.transmitter, player, unpack({...}));
