I am new to truffle and I work on blockchain project so when I "migrate" in truffle develop, this error occurs. Why ? I change the version of my compiler by 4.25 in truffle-config.js but nothing has changed. Thanks in advance for your help.
This could help:
truffle migrate --reset
This works for me:
npm un -g truffle
npm i -g truffle#nodeLTS
I had this same error. I tried the other fixes posted, and Javi's did work for me. All I had to do was downgrade to node v10 from v12.
You can use n to do this:
sudo npm install -g n
sudo n stable
sudo n 10.3
Are you using node v12?
If you are using v12 then try to use v10.
You can install NVM and use node v10 in this project.
You could try
truffle develop
and then
migrate --reset
I got the same issue, and the basic solution I found out is to change the truffle version to the current version.
npm install -g truffle
which will install the current version of truffle

Compiling your contracts...
===========================
Error: SyntaxError: Unexpected end of input

I couldn't even locate this index.js file. Where could this be?
Check your contract pragma statement or truffle config.
If you might be compiling against wrong solidity compiler.
