Answer 1

我在该主题上进行了更多搜索，似乎是使用sudo安装一些meteorite需要的软件包时出现的问题。正如此 Github 问题页面上所建议的，解决此问题的一种方法是删除/.meteor/local/build应用程序中的文件夹并重新启动 Meteor。

Answer 2

这对我/.meteor/local/build有用:重新设置(以避免使用sudo)对用户的chown权限.

例如,我的用户是"skozz".在我的项目文件夹中:

sudo chown -R skozz .meteor/local/build

然后跑mrt或meteor

如果问题仍然存在,您可能应该为主.npm文件夹设置相同的权限.就我而言:

chown -R skozz ~/.npm
