I am following the process from https://hardhat.org/tutorial/creating-a-new-hardhat-project to create a new hardhat project.
However, it is throwing an error in the contract compiling step; i.e. when I run yarn hardhat compile
Downloading compiler 0.8.9

I'm running the code on windows with WSL using
node v16.13.2
yarn v1.22.15
hardhat v2.11.2
Here are my WSL configs
BUILD: 19042
BRANCH: vb_release
RELEASE: Ubuntu 20.04.3 LTS
KERNEL: Linux 4.4.0-19041-Microsoft
UPTIME: 0d 3h 18m
Here's my hardhat.config.js
require("#nomicfoundation/hardhat-toolbox");
/** #type import('hardhat/config').HardhatUserConfig */
module.exports = {
solidity: "0.8.9",
};
Here's my repo link: https://github.com/J0SAL/hardhat-simple-storage
The code and everything are correct.
I found the issue in my WSL setup.
Right now I'm using Windows PowerShell and it's working fine.
I just installed shiny server and I get an error when I load the shiny web page:
An error has occurred. The application failed to start shows on the right side of the screen.
Then I checked the log and shows:
su: ignore --preserve-environment, it's mutually exclusive to --login.
Fatal error: unable to open the base package
When I type su - shiny and I try to run R I also get the Fatal error: unable to open the base package, so I guess there is a problem with R.
I can load R when I'm root or R user and apparently R works fine.
Any idea? Could it be a PATH problem? If yes, I couldn't find it out.
Thanks in advance.

I install Erl7.3 and rabbitmq-server 3.6.2. I using Win7 32bit. After installing when I run 'rabbitmq-server' command it gives:
ERROR: node with name "rabbit" already running on "admin-PC"
When I run 'net stop RabbitMQ && net start RabbitMQ' it stopped RabbitMQ service and restarted successfully.
After that When I run "rabbitmq-plugins enable rabbitmq_management", it gives following errors and nothing is shown at http://localhost:15672:
Plugin configuration unchanged.
Applying plugin configuration to rabbit#admin-PC... failed.

For your information, I set environmental variables as:
'Variable name: ERLANG_HOME', 'Variable value: C:\Program Files\erl7.3';
'Variable name: RABBITMQ_SERVER', 'Variable value: C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.2'
and system path "%ERLANG_HOME%;;%RABBITMQ_SERVER%\sbin"
How to resolve this errors?
rabbitmq management plugin needs the cryptopakage to work.
see:
Error: {undef,[{crypto,module_info,[attributes],[]},
{rabbit_misc,module_attributes,1,
Try to use the Erlang 18.3 version.
EDIT
After installing when I run 'rabbitmq-server' command it gives:
ERROR: node with name "rabbit" already running on "admin-PC"
This is normal since rabbitmq-server starts the server, but you have rabbitmq installed and running as windows service.
And you should use the 64 bit version
I am about to begin a project with Shiny (by RStudio). When I try to install the shiny package using the console install.packages("shiny"), I get the following error message:
trying URL 'http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/shiny_0.10.1.tgz'
Warning in install.packages :
cannot open: HTTP status was '404 Not Found'
Error in download.file(url, destfile, method, mode = "wb", ...) :
cannot open URL'http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/shiny_0.10.1.tgz'
Warning in install.packages :
download of package ‘shiny’ failed
I have tried to install it from the drop down menu in RStudio but have encountered the same problem. Any thoughts as to what is going on?
I am working on Mac, with the latest version of Mavericks (R version is 3.1.1).
Thanks,
Brian
Try a different CRAN mirror. The error indicates that the file was not found on the CRAN server
chooseCRANmirror()
shiny has just been updated 2014-10-01 so the changes may not have propagated down to all mirrors yet.
