I can't run truffle commands in powershell Ise

Question

I am looking around for questions similar to mine but basically I cannot run any truffle commands in the powershell Ise ONLY. I can make it run on the node.js command line.

example:

> PS C:\Users\user\Documents\internship\Blockcerts\proof-of-existence-master>
> truffle compile truffle : The term 'truffle' is not recognized as the
> name of a cmdlet, function, script file, or operable program. Check

> + truffle compile
> + ~~~~~~~
>     + CategoryInfo          : ObjectNotFound: (truffle:String) [], CommandNotFoundException
>     + FullyQualifiedErrorId : CommandNotFoundException

I tried to follow up a similar question where the answer was to uninstall and install the following but this still occurs.

Answer 1

Please Try it If it was working alright previously, uninstalling and reinstalling truffle should work. npm uninstall -g truffle npm install -g truffle

-g truffle install then work the issue.

In case this does not work, below will work.

run npm init #then will make a new npm project particularly package.json
run npm i truffle #then will download node modules 
run ./node_modules/.bin/truffle init #then will create a truffle project

Try it

Thank You!

Answer 2

set the path in the environment variable:

Answer 3

Try the following

1.Create a director coin and a sub-directory authcoin

2.cd to coin

run npm init #then will make a new npm project particularly package.json
run npm i truffle #then will download node modules 
run cd authcoin/
run ./../node_modules/.bin/truffle init #then will create a truffle project

or if you run last command in coin directory the error might occur.

Error: Something already exists at the destination. `truffle init` and     `truffle unbox` must be executed in an empty folder. Stopping to prevent overwriting data.
