So it looks like it is installing correctly but there are a lot of warnings! It would be nice if we could go through and update a lot of our dependencies. This would make sure we have the best versions and hopefully eliminate a lot of that output. Thanks for bringing this up!

[MiStErDaNgErR]

How can I fix this?

[eggplantzzz]

What exactly do you want to fix? The warnings are most likely coming from dependencies of dependencies. So we would have to upgrade Truffle's dependencies to newer versions that do not have warnings. The warnings won't harm anything for now, they look to be all deprecation warnings. Ideally we would upgrade these to newer versions though.

[MiStErDaNgErR]

thank you for ur work but i cant use it if i use 'truffle -version' it shows not found so i am not able to use truffle which I require for my college project. thats it. keep up the goodwork ;)

[eggplantzzz]

Oh so you are saying that after installation, if you try and execute truffle version it fails? What error does it give you? How are you installing Truffle?

[Tanteli]

@MiStErDaNgErR How did you solve this issue ?

[ChainCrawlerX]

The correct syntax is 'truffle version', not 'truffle -version'. Your installation is likely operating as intended. There is however still a slew of deprecated warnings, which we are all getting. Later Truffle versions should address this, but you can move forward with your project.
