执行这里一直卡住，无法执行，通过调试发现，是

build/check-versions.js里面

\'use strict\'const chalk = require(\'chalk\')const semver = require(\'semver\')const packageConfig = require(\'../package.json\')const shell = require(\'shelljs\')function exec (cmd) { return require(\'child_process\').execSync(cmd).toString().trim()const versionRequirements = [ name: \'node\', currentVersion: semver.clean(process.version), versionRequirement: packageConfig.engines.nodeif (shell.which(\'npm\')) { versionRequirements.push({ name: \'npm\', currentVersion: exec(\'npm --version\'), versionRequirement: packageConfig.engines.npm

exec(\'npm --version\')无法执行造成的问题，因此，将这个值直接填写

if (shell.which(\'npm\')) { versionRequirements.push({ name: \'npm\', currentVersion: \'5.6.0\', // exec(\'npm --version\'), versionRequirement: packageConfig.engines.npm

然后这个问题解决了。
