安装 node.js、npm 和无服务器时出错

Question

我正在尝试使用此处找到的以下命令在我的笔记本电脑中安装node.js和npm ：

# Using Ubuntu
curl -sL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
sudo apt-get install -y nodejs

这些安装Node.js LTS (v12.x) 。

在此之后，我尝试安装serverless ，如下所示。

我愿意：

npm install -g serverless

并抛出以下错误

cortex@cortex-Lenovo-ideapad-720S-15IKB:~$ npm install -g serverless

我是node.js的新手，所以有人可以帮我解决这个问题吗？

附言：

node -v的 output 是 v12.18.3

npm npm -v的 output 是 6.14.6

安装全局 package 时使用 sudo。

sudo npm install -g serverless
