Facing an error while running "truffle compile"

Question

I'm facing an error while running truffle compile-

Error: Failed to fetch the Solidity compiler from the following locations: https://relay.trufflesuite.com/solc/bin/,https://solc-bin.ethereum.org/bin/,https://ethereum.github.io/solc-bin/bin/. Are you connected to the internet?

Here is my truffle-config.js -

require("babel-register");
require("babel-polyfill");

module.exports = {
  networks: {
    development: {
      host: "HTTP://127.0.0.1:",
      port: "7545",
      networkd_id: "*", //match any network
    },
  },
  contracts_directory: "./src/contracts/",
  contracts_build_directory: "./src/truffle_abis",
  compilers: {
    solc: {
      version: "^0.5.0",
      optimizer: {
        enabled: true,
        runs: 200,
      },
    },
  },
};

Answer 1

Run npm doctor to check your node environment health, this should fix the problem.

If it persists, consider downloading node.js using a version manager like nvm, then rerun npm doctor. this way you won't have to use sudo truffle compile.

Answer 2

My env is MACOS. I meet the same problem, and I solve this by using "sudo truffle compile".This works. this problem comes out with my webstorm integrated terminal.But in the MACOS's self-terminal. It works without "sudo".You can try my way.
