aws-ec2 上的权限问题

Question

我正在尝试让我的 nodejs 项目在 aws-ec2 上运行。 我在尝试安装 bower 时遇到权限问题：

当我尝试 sudo 得到的命令时

sudo: npm: command not found

解决方案

我在这里用选项 1 解决了 https://docs.npmjs.com/getting-started/fixing-npm-permissions

Answer 1

如果你得到

sudo: npm: command not found

那么你必须将它添加到你的 PATH 变量中。

在 ElasticBeanstalk 中像这样：

export PATH=/opt/elasticbeanstalk/node-install/node-v6.10.0-linux-x64/bin:$PATH
