在MacOS Catalina上安装npm live-server

问题描述

我正在尝试安装npm live-server，但是出现以下错误：

stl34>>npm install live-server -g

问题似乎是/usr/local/lib/node_modules的文件权限需要更改。 我尝试以恢复模式重启并输入终端：

csrutil disable

禁用SIP。然后，我重新启动并在终端中输入以下内容：

sudo mount -uw /

chmod 775 usr/local/lib/node_modules

但是系统仍然不允许我修改文件权限。我该怎么做才能修改它们？

另一个用户在这里问了同样的问题： NPM Live-server not installing on zsh 但没有得到答案。

解决方法

运行“sudo npm install live-server -g”对我有用
