Chocolatey fails to install Inno Setup on Azure Pipeline - azure-devops

Question

I am trying to install Inno Setup 5 on the built in VS2017 agent on Azure Devops for one of my build pipelines but I am getting the following two lines in the stdout but it exits with a code of 1 and there is nothing in the log files. My question(s):
Does Inno Support being installed in this way?
What am I doing wrong?
Does chocolatey require being run on machine with a logged in GUI?
Here are the two lines from stdout that I think are most important
innosetup not installed. An error occurred during installation:
The process cannot access the file '...\.chocolateyPending' because it is being used by another process.
Here is my build pipeline on Azure Devops:
My installer script is written in javascript and executed via npm script after installing dependencies
const utils = require('./utils');
const fs = require('fs');
const path = require('path');
const spawn = require('child_process').spawn;
const command = 'cmd /c choco install innosetup --yes --force --no-progress -ia \'/VERYSILENT\'';
const logDirectory = path.join( 'C:', 'ProgramData', 'chocolatey', 'logs' );
function install() {
return new Promise( resolve => {
const cmd = command.split(' ').filter( ( x, i ) => i === 0 ).join('');
const args = command.split(' ').filter( ( x, i ) => i !== 0 );
var sqlcmd = spawn( cmd, args );
sqlcmd.stdout.on( 'data', data => {
console.log( data.toString().replace( /\r\n$/gmi, '' ) );
} )
sqlcmd.stderr.on( 'data', data => {
console.error( 'error', data.toString() );
process.exit( 1 );
} )
sqlcmd.on( 'exit', code => {
resolve( code );
} )
});
}
( async () => {
utils.header( 'installing Inno Setup' );
const installExitCode = await install();
utils.header( 'Log directory:', logDirectory );
console.log( ' *', fs.readdirSync( logDirectory ).join( '\r\n * ' ) );
utils.header( 'chocolatey.log' );
fs.createReadStream( path.join( logDirectory, 'chocolatey.log' ) ).pipe( process.stdout );
utils.header( 'choco.summary.log' );
fs.createReadStream( path.join( logDirectory, 'choco.summary.log' ) ).pipe( process.stdout );
if ( installExitCode !== 0 ) {
console.log( 'installer exited with error code:', installExitCode );
process.exit( installExitCode );
}
})();
Here is the stdout I am getting from the failed Azure Devops build:

Answer 1

To answer some of your direct questions...
Does Inno Support being installed in this way?
Yes, innosetup does support being installed this way. You can see that on the packages page here. That green bulb at the top of the page is an indication that this package version correctly installed via the automated processes that Chocolatey has, verifying that a package installed correctly.
Does chocolatey require being run on machine with a logged in GUI?
No, this is not necessary in most cases. There are some Chocolatey packages that don't install silently, and the mechanism used to install these "may" require the installation to be running in an actual User process, but the majority of packages don't need this.
What am I doing wrong?
I have a suspicion that "something" isn't working correctly when running through npm, and being installed within a Promise. Looking at the log, there seems to be this entry:
2019-01-22T18:34:19.0339462Z Item has already been added. Key in dictionary: 'NPM_CONFIG_CACHE' Key being added: 'npm_config_cache'
In the middle of the Chocolatey log, which doesn't make sense to me.
My best advice would be to use the standalone Chocolatey Task on this extension (NOTE: Full disclosure, I am the author of this extension), or, attempt to do the installation outside of npm, perhaps directly with a PowerShell Task.
