sh: 1: vue-cli-service: Permission denied npm ERR! code ELIFECYCLE npm ERR! errno 126 npm ERR! my-pr

在linux环境下，用npm run build编译打包前端，报以下错误：
sh: 1: vue-cli-service: Permission denied
npm ERR! code ELIFECYCLE
npm ERR! errno 126
npm ERR! [email protected] build: vue-cli-service build
npm ERR! Exit status 126
npm ERR!
npm ERR! Failed at the [email protected] build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR! /root/.npm/_logs/2019-06-13T01_50_16_049Z-debug.log

看提示 Permission denied好像是没有权限
于是，我在本地cmd打包 是ok的，我怀疑不是程序的问题，于是我就用chmod -R 项目文件夹，然后在打包一次就好了。
