错误：无法获取 Solidity 编译器

Question

I am new to Truffle and going through the Metacoin tutorial; I followed all the steps but when I do truffle compile, I get the following:

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?

I am connected to Internet and using: Truffle v5.5.26 (core: 5.5.26) Ganache v7.4.0 Solidity - 0.8.13 (solc-js) Node v16.13.1 Web3.js v1.7.4

Answer 1

你永远不应该逃跑sudo按照上述答案的建议运行。尽管它可以工作，但由于您向这些软件包授予了管理员权限，因此它会使您的 PC 受到攻击。

相反，您应该运行npm doctor来检查节点环境运行状况。这应该可以解决问题。
