linux - 在 mozjpeg 上安装 npm 时出错，权限被拒绝？

Question

我正在运行 npm install 并收到以下错误:

> mozjpeg@5.0.0 postinstall /home/MyUser/public_html/node_modules/mozjpeg
> node lib/install.js

这似乎是缺少权限，但我不明白为什么。如果我以 root 运行相同的命令，一切正常。我缺少什么权限，我该如何解决？

谢谢。

在 xubuntu 17.10 上也有同样的问题，我所做的是安装 libpng-devsudo apt-get install libpng-dev 然后再次运行 npm install。这解决了我的问题
