Does the ClearScriptV8.win-x64.dll
file exist in the bin
directory?
Yes, it is exist.
Hello!
Starting from version 3.9.0, JavaScriptEngineSwitcher.V8 module is no longer responsible for deploying and loading the native assemblies (corresponding functionality is now implemented in the Microsoft.ClearScript.V8.* packages).
Unfortunately, modern versions of NuGet do not always work stable with .NET Framework projects and because of this, sometimes there are failures after installing packages. Therefore, I recommend you to perform a clean installation:
.csproj
file, remove lines like these:
<Import Project="..\packages\Microsoft.ClearScript.V8.Native.win-*\build\Microsoft.ClearScript.V8.Native.win-*.props" Condition="Exists('..\packages\Microsoft.ClearScript.V8.Native.win-*\build\Microsoft.ClearScript.V8.Native.win-*.props')" />
<Error Condition="!Exists('..\packages\Microsoft.ClearScript.V8.Native.win-*\build\Microsoft.ClearScript.V8.Native.win-*.props')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\Microsoft.ClearScript.V8.Native.win-*\build\Microsoft.ClearScript.V8.Native.win-*.props'))" />
bin
and obj
directories.… DartSassHost: 1.0.8.0 … LibSassHost: 1.2.10.0
If you are using the latest version of the BundleTransformer.SassAndScss module, then I recommend that you remove the LibSassHost packages (see the corresponding section of documentation).
Thanks for your response.
I uninstalled every thing about BundleTransformer and JavaScriptEngineSwitcher from project. I installed again packages (last version) but I still got error:
Could not load file or assembly 'file:///D:\.Net Project\Project Pathbin\ClearScriptV8.win-x64.dll' or one of its dependencies. The module was expected to contain an assembly manifest.
Try to make a demo console application:
Program.cs
file with code similar to this:
using System;
using Microsoft.ClearScript.V8;
namespace TestClearScriptV8 { internal class Program { static void Main(string[] args) { using (var engine = new V8ScriptEngine()) { var result = (int)engine.Evaluate("2 * 2"); Console.WriteLine("Result: {0}", result); } } } }
5. Launch the console application.
I created a console application and that is works fine! But still I have error in asp.net mvc project (with .net framework 4.7.2)
In unedited version of the previous message it is written:
I create a console application in net framework 4.7.1 and 4.7.2 (I don't have .net framwork 4.5) but I still got error.
Cannot load ClearScript V8 library. Load failure information for ClearScriptV8.win-x86.dll: D:\Sources\ConsoleApp3\bin\Debug\runtimes\win-x86\native\ClearScriptV8.win-x86.dll: The specified module could not be found D:\Sources\ConsoleApp3\bin\Debug\ClearScriptV8.win-x86.dll: The specified module could not be found'
After what changes did the console application start working?
That was my mistake and application was x86 then I changed to x64 works fine. But my asp.net project is in x64.
Try installing two packages at once into your web application: Microsoft.ClearScript.V8.Native.win-x86 and Microsoft.ClearScript.V8.Native.win-x64.
If this error still occurs, then try to reproduce the error in the form of simplest demo web application and send me a link to it.
I create a simple MVC application and used BundleTransformers. I found my problem. I used V8JsEngine before and that has error for v8-lib-cpp or ClearScript-X64.exe and not workes. I updated all of my packages to last version and used MsieJsEngine for AutoPrefixer jsEngine instead of V8JsEngine and resolved my problem.
Hi my friends After updating the BundleTransformer packages in my ASP.NET MVC project, I encountered a critical issue that is preventing the project from running successfully. Prior to the update, I was using BundleTransformer along with JavaScriptEngineSwitcher, and everything was working fine. However, after the update, the project fails to start, and I receive the following error:
Could not load file or assembly 'file:///D:\Project Path\bin\ClearScriptV8.win-x64.dll' or one of its dependencies. The module was expected to contain an assembly manifest.
Troubleshooting Steps Taken: Updated BundleTransformer packages to the latest versions. Updated ClearScriptV8.win-x64.dll to version 7.4.4.0 as specified. Switched from JavaScriptEngineSwitcher.V8.Native.win-x64 to Microsoft.ClearScript.V8.Native.win-x64 as recommended. Despite the changes, the issue persists.
Package Versions Used: ClearScript.V8: 7.4.4.0 MsieJavaScriptEngine: 3.2.2.0 DartSassHost: 1.0.8.0 AutoprefixerHost: 1.1.10.0 BundleTransformer.Core: 1.10.0.0 JavaScriptEngineSwitcher.Core: 3.21.0.0 LibSassHost: 1.2.10.0 System.Text.Encodings.Web: 8.0.0.0 (updated during the process)
Additional Information: The update process for System.Text.Encodings.Web resulted in an error, but the package was successfully updated to version 8.0.0.0.
Request for Assistance: I kindly request assistance in resolving this issue and getting the project back to a stable state. Any guidance on further troubleshooting or specific package versions compatibility would be greatly appreciated.
Thank you for your time and support.
