[Ethereum] Can not install Ganache GUI on Ubuntu

One relatively easy solution is to install node.js and use the solc npm package. I used it myself when I initially started playing with ethereum contracts and it was a snap to set up.

Here are the steps -

• install the latest version of node.js
• create a folder for the project

• add solc package to your package.json file, or use the following package file -

  { "name": "eth_compiler", "version": "0.0.1", "engines": { "node": ">=7.0.0", "npm": "^3.0.0" }, "dependencies": { "solc": "^0.4.7" } }

• run npm install in the folder

• add a small js script to the folder (compile.js) - it will receive the contract file name and output the abi/code files you need.

Here's a example -

var solc = require('solc');
var fs = require('fs');

var inputFilePath = process.argv[2];
var outputPath = process.argv[3];

// note - using the synchronous version of the file system functions for simplicity and because the async version isn't really needed in this case
var contractSolidity = fs.readFileSync(inputFilePath , 'utf-8');
if (!contractSolidity)
    return console.error('unable to read file: ' + inputFilePath );

var output = solc.compile(contractSolidity, 1);
for (var contractName in output.contracts) {
    var abi = output.contracts[contractName].interface;
    var code = output.contracts[contractName].bytecode;
    fs.writeFileSync(outputPath + '/' + contractName + '.abi', abi, 'utf-8');
    fs.writeFileSync(outputPath + '/' + contractName + '.code', code, 'utf-8');
}

• once you have that file, you can simply execute the following command in the new folder - node compile [inputFilePath] [outputPath]

and it should generate the compiled files.

Note: I did test it locally and managed to compile a contract so I believe it should work but it's worth mentioning that I have both party & cpp-ethereum installed on my machine (parity wasn't running at the time of this script's execution).

Why don't you simply run npm install -g truffle to install truffle,, with TestRPC as your Ethereum client, you can install TestRPC using the command npm install -g ethereumjs-testrpc

It worked for me this way
