Learning Truffle

mcgrane5 · May 3, 2022, 3:32pm

when does this error come. is it when you try to npm install truffle or when you try to run truffle init or when you try to do a command like truffl ecompile or truffle migrate??

Heyns · May 4, 2022, 7:29am

This error first came when I did truffle init (the truffle compile or truffle migrate i don’t know), but after I reinstalled truffle i saw this in the node.js screen right after the install.

can someone help please

mcgrane5 · May 4, 2022, 8:33am

Heyns · May 4, 2022, 10:35am

this is what I get in my virtual studio terminal. Just to be clear

I noticed it says µWs is not compatible with your Node.js build … but I don’t find what I should do

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See npm help init for definitive documentation on these fields
and exactly what they do.

Use npm install <pkg> afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.

I see truffle has a VS code extension now. I haven’t used it but was curious if anyone else has? Is it recommended to be using that instead when creating projects on our own?

mksdznk · June 21, 2022, 11:26pm

Hello, I am trying to install truffle but am running into some problems. The first thing I did was download and install node.js 16.15.1, and then went to my computer`s command prompt and attempted to install truffle, which didn’t work so I uninstalled and tried to reinstall with --force. Do I need to do anything else first, any help would be appreciated.
Thanks

Hudsen · June 22, 2022, 12:46pm

Hey, I was having the same problem yesterday. I think I fixed the location problem by updating my npm with the following steps.

mksdznk · June 22, 2022, 7:54pm

No luck with that either, thanks anyways. Any other ideas?

thecil · June 22, 2022, 11:37pm

after installing truffle with npm, you can try to run truffle -v and it should return the version of your truffle package, meaning that truffle has installed properly and its ready for being use.

If the command is not working, you can try with npx truffle -v, the WARN messages are just warnings that some packages should upgrade, but this will not stop the functionality of truffle, so nothing to worry about them.

mksdznk · June 24, 2022, 12:49pm

I’m guessing this isn’t a good output, right?

mksdznk · June 25, 2022, 8:11pm

After doing some research through some other forums and some trial & error, I found that if I downloaded a specific version of truffle (in my case 5.4.29), using the command npm install -g [email protected] truffle would successfully install, do you think this solution will be good enough?

Thanks,

thecil · June 27, 2022, 5:59pm

Yes, that should be enough, still let me know if it works for you.

Carlos Z

seybastiens · July 21, 2022, 1:42pm

I got these errors when installing Truffle (on Macbook Pro). Seems like it works though but do you think it will be problematic at some point ?

thecil · July 22, 2022, 11:54pm

Nothing to worry about, those are warning messages on modules used by the package you are installed.

Carlos Z

seybastiens · July 23, 2022, 6:39am

the problem is that later on, when I try to deploy the Helloworld contract, I get these errors and I’m not sure how to fix them.

Kacper · July 23, 2022, 5:12pm

When Filip type ‘truffle deployed’ in terminal then he gets node instead of cmd.
Why my terminal doesn’t transform to node if I type that?

I have such an error:
