如何使用 gulp build 运行 node.js 项目

Question

我试图在 ubuntu (linux) 机器中使用 gulp 构建运行 node.js 项目。 当我尝试安装“sudo npm install”时，它总是显示以下错误：

    > sharp@0.19.1 install /home/east/Documents/rht/PlateRate/BackUp/PlateRate_2686/node_modules/sharp
> node-gyp rebuild

即使在那之后，当我尝试 sudo gulp build 时，它再次显示以下错误：

请大家帮帮我。

谢谢，

发生这种情况是因为对 npm 的权限不足，无法创建目录 '/home/east/Documents/rht/PlateRate/BackUp/PlateRate_2686/node_modules/sharp/build'。

要解决这个问题，请将 npm 的默认目录更改为您的主文件夹中的隐藏目录：

mkdir ~/.npm-global npm config set prefix '~/.npm-global' export PATH=~/.npm-global/bin:$PATH source ~/.profile

希望这会奏效。
