I updated to the latest version of Truffle
using:
npm uninstall -g truffle
followed by:
npm install -g truffle
I verified this succeeded by doing:
truffle --version
and got this:
You can clearly see that I'm on version 5.0.3
I read that updating Truffle
would pretty much also automatically update the Solidity
compiler.
but when I do:
solc --version
I get this:
So its still on version 0.4.24
So I did again.
And again.
And its not working.
I've done it globally - and I've done it locally, meaning in my specific project's Directory.
Nothing works.
I tried doing it directly, by uninstalling Solidity - like this:
npm uninstall solc -g
-then reinstalling it using:
npm install solc -g
I've done pretty much everything I can think of, but its still telling me that I'm on version 0.4.24
.
What's going on? What am I missing here?
========================================================
UPDATE:
I added the following to my truffle.js
file:
compilers: {
solc: {
version: "0.5.0" // ex: "0.4.20". (Default: Truffle's installed solc)
}
}
That's obviously supposed to force the use of that particular version of the compiler.
I recompiled and redeployed to ropsten
- and that all worked.
So at this point, I'm assuming that the project is being compiled using v 0.5.0 of Solidity - but is it?
Here's my big question right now: how can I tell - like during run time, what compiler version is actually being used on my project at any given time?
Cause at this point, I'm still getting errors in my DApp - the HTML & JS files that are querying the contract I deployed - that seem to do with the compiler+solidity versions - which was the reason I updated truffle
to version 5 in the first place, to solve these issued. (But that's another matter. One thing at a time.)
===========================================================================
UPDATE#2
This shows everything:
-I'm installing solc v. 0.5.3 directly into my project's folder (I've already done the Global install several times.)
-I get 2 warnings - I don't know what they mean - but it says it installed 14 packages from 5 contributors
, which sounds pretty good.
-but then when I do solc version
, it tells me I'm on version 0.4.24
I've literally spent all day trying to resolve this.
