unable to configuration postcss

I have the configure Autoprefixer postprocess file knowing psysical path, it throws below error

I also install JavaScriptEngineSwitcher.Msie (only in the Chakra JsRT modes)

JavaScriptEngineSwitcher.V8
JavaScriptEngineSwitcher.ChakraCore

System.Configuration.ConfigurationErrorsException
HResult=0x80131902
Message=In the name attribute of /configuration/bundleTransformer/autoprefixer/jsEngine configuration element not specified a name of JS engine.

If you have not installed JS engine, then for correct working of this module is recommended to install one of the following NuGet packages:

JavaScriptEngineSwitcher.Msie (only in the Chakra JsRT modes)
JavaScriptEngineSwitcher.V8
JavaScriptEngineSwitcher.ChakraCore

After package is installed and JS engine is registered (https://github.com/Taritsyn/JavaScriptEngineSwitcher/wiki/Registration-of-JS-engines), need set a name of JS engine (for example, MsieJsEngine) to the name attribute of /configuration/bundleTransformer/autoprefixer/jsEngine configuration element.

Hello!

You need to install a JS engine and configure it. In the error message describes the entire process. Just in case, I give a link to the module documentation.

Hi Taritsyn,

Thanks for your reply

Bundler Transformer Autoprefixer postprocess file knowing psysical path

have a project in ASP.NET MVC and I want to use Bundler Transformer Autoprefixer to process my css files. My use case is a little bit unusual and I need to process css content from physical path like "d:\somewhere\style.css". I think I can use AutoprefixCssPostProcessor class to do so, but it allows to process assets, that require virtual path to the file. Is it possible to postprocess such file using AutoprefixCssPostProcessor?

please refer the code snippet for web.config file

Hi Taritsyn,

How can I achieved the physical path for css file, if any alternative here? if possible to pass the css content to autoprefixer, please share the example ?

Answer 7 · 2019-06-24T07:28:35.000Z

I already wrote that this feature is not supported. In your case, I recommend experimenting with running of the Node.js modules by using the Edge.js library.

Hi Taritsyn,

Thanks for your reply, I'm try this, but it throws below error

AutoprefixerHost.AutoprefixerLoadException
HResult=0x80131500
Message=During loading of the Autoprefixer error has occurred. Failed to create instance of the ChakraCoreJsEngine. Most likely it happened, because the 'ChakraCore.dll' assembly or one of its dependencies was not found. Try to install the JavaScriptEngineSwitcher.ChakraCore.Native.win-x86 package via NuGet. In addition, you still need to install the Microsoft Visual C++ Redistributable for Visual Studio 2017 (https://www.visualstudio.com/downloads/#microsoft-visual-c-redistributable-for-visual-studio-2017).

There is a hint in the error message:

Try to install the JavaScriptEngineSwitcher.ChakraCore.Native.win-x86 package via NuGet. In addition, you still need to install the Microsoft Visual C++ Redistributable for Visual Studio 2017 (https://www.visualstudio.com/downloads/#microsoft-visual-c-redistributable-for-visual-studio-2017).

Also, JavaScriptEngineSwitcher.ChakraCore and JavaScriptEngineSwitcher.ChakraCore.Native.win-x86 packages must have a version 3.1.1.
