【问题讨论】：

尝试添加npm，然后以管理员身份运行meteor。
您的用户无权访问 /home/john/.npm/connect/2.9.0/package/package.json 尝试：sudo chown -R john ~/.npm

标签： meteor

【解决方案1】：

如果您使用 用户权限 运行初始命令（从您的回答中不清楚 - 请下次打印命令），那么它需要能够访问（读取、写入、执行) 其他具有相同权限的目录。

您可以通过以下方式更改所有权：

chown -R $USER <directory>

在您的情况下，<directory> 是 /home/john，-R 用于递归，因此它也会更改所有子目录，这正是您想要的。
