Azure DevOps - npm invisible - npm

I have a strange problem with a release pipeline in Azure DevOps.
I have two tasks:
1) Install packages
2) Run npm using the above packages
All seems to be easy so what I do is:
1) Command line task
npm install -g mkdirp 1.0.3
npm install -g newman
npm install -g newman-reporter-junitfull
2) PowerShell task
$(newman run $collection -e $environment --env-var "x=$(x)" -r junit --reporter-junit-export $resultFile)
This all worked fine until today. I tried a lot, but nothing works.
The error I have is:
newman : The term 'newman' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the
name, or if a path was included, verify that the path is correct and
try again.
Did anyone have a similar issue?

I ran above npm install scripts in a Command line task, and found only the first npm install command got executed. And my following powershell task to run newman command failed with above error message too. You can check the log of Command line task to see if it is the same issue.
If you want to report this issue, you can report a problem here.
The workaround i found is to run the npm install commands in a Powershell task too, do not use Command line task. Then the npm install commands will all get executed and the following powershell task can run successfully.
Or you can separate above three npm install commands into three Command line tasks to install them separately, which will make sure the newman library is installed.

NPX command not running in Azure pipeline

I need your help
I was trying to run my cypress test cases which I generally run using command
"npx cypress run"
so I tried to have the same command in tasks when I created Azure pipeline
after NPM Install
I even tried installing npx via
npm task and custom command "npm install nx"
and this causing the below issue so can anyone suggest to me how to proceed in this case
"##[warning]Couldn't find a debug log in the cache or working directory
##[error]Error: Npm failed with return code: 1
"
From the error screenshot, it shows that you are using the Npm Task and running the command: npm npm install nx.
The command is invalid.
To solve this issue, you need to remove the npm in the NPM task -> Command and arguments .
Refer to the following sample:
YAML Pipeline:
- task: Npm#1
displayName: 'npm custom'
inputs:
command: custom
verbose: false
customCommand: 'install nx'
Classic Pipeline:

Visual Studio Code - NPM not found when using NPM SCRIPTS

If I open the integrated terminal and run npm -v it works.
But, if I running it directly from NPM SCRIPTS it doesn't work.
MORE DETAIL AS REQUESTED IN COMMENT
// Edit by Fogmeister
I also have this problem, here is some more detail...
I have a test script defined in package.json...
When I run this script from the root folder command line using npm run test it works...
This script appears in the list of NPM Scripts in VS Code...
When I run from the NPM Scripts explorer it fails...
Even though it says it is running from the same folder.
Try doing, use dnf or apt-get
sudo apt-get/dnf install npm
The npm file should be in /usr/local/bin/npm. If it's not there, install node.js again with the package on their website.

What is the difference between yarn run and npm start?

Is yarn run intended to be the equivalent of npm start?
It seems yarn run start is the equivalent of npm start, which runs the script inside the start field of the script field in package.json
Few things to understand:
npm: run command is mandatory to execute user defined scripts.
yarn: run command is not mandatory to execute user defined scripts.
start command is not a user defined script name, so you may not need to specify run command to execute it.
So, all the below commands work similar!
npm start
npm run start
yarn start
yarn run start
If you have a user defined script named 'app':
npm app (Does not work!)
npm run app (Works!)
yarn app (Works!)
yarn run app (Works!)
Note: By default start runs node server.js in case not explicitly defined.
npm start is a shortcut for npm run start
Now in terms of running scripts from package.json, all these are equivalent:
npm run start
npm start
yarn run start
yarn start
npm run myscript
npm myscript this is an error
yarn run myscript
yarn myscript
This is because run is not mandatory command for yarn, but it is for npm.
Bonus
npr start - OK
npr myscript - OK
Put this file somewhere in PATH, eg. %localappdata%\Programs\Git\cmd
npr.cmd
npm run %*
yarn run is similar to npm run, they can be used to run the scripts in package.json.
For npm, you can leave out run when run the npm lifecycle scripts (test, start, restart, and stop), but these scripts maybe have extra effect. For example, npm start will run node server.js if the "scripts" object does not define a "start" property in package.json. see the doc npm run. You can't run script with other name leaving out run.
For yarn, you can leave out run for all the scripts in package.json, but if your script name is same as yarn built-in cli commands, the built-in cli commands will have preference over your scripts. doc yarn run.
So the best way to run scripts in package.json: never leave out run.

migrate command not found error even if migrate is installed

I have executed command -
npm install migrate
and it has executed successfully. But when I try to execute the command migrate in terminal it gives me error as migrate command not found
Please find image here.
Has anyone got the same error?
try installing it globally
npm install migrate -g
I have two solutions to this problem.
The first is to attempt to install the package globally.
npm install -g migrate
If above  solution not worked, it could be due to the current user's undefined ExecutionPolicy.
As an administrator, run the following PowerShell command:
Set-ExecutionPolicy RemoteSigned

I get an error during Gulp installation

I'm trying to setup Gulp on my system. As I type in the command "npm install gulp" in the command prompt, I'm shown an error . Please help me install Gulp. I access the command prompt from my office which has limited internet access.
It says npm cannot connect to its registry, try to use npm install with another key. It shouldn't work too.
npm config set registry http://registry.npmjs.org/
Try to run this on command.
