我想在Ubuntu上安装Maitrain。在这个过程中，我安装了Node包。但安装时出现错误。有人知道如何解决这个问题吗？

cd /var/www/mailtrain
sudo npm install --no-progress --production --unsafe-perm=true

During the Npm install I get a lot of errors then mailtrain service could not be started.

> posix@4.1.2 install /var/www/mailtrain/node_modules/posix
> node-gyp rebuild
