出现原因
truffle-config.js 配置文件中

compilers: {
    solc: {
       // version: "0.5.1",    // Fetch exact version from solc-bin (default: truffle's version)
       // docker: true,        // Use "0.5.1" you've installed locally with docker (default: false)
       settings: {          // See the solidity docs for advice about optimization and evmVersion
        optimizer: {
          enabled: false,
          runs: 200
        },
        //evmVersion: "byzantium"
       }
    },
  },

需要将 docker 注释掉，或者为false
