node.js - E : Unable to locate package npm

Question

当我尝试使用 sudo apt-get install npm 安装 npm 时，出现以下错误:

E: Unable to locate package npm

为什么apt找不到npm？我正在使用 Debian 9 并且已经运行了

sudo apt-get install nodejs

Answer 1

来自官方 Node.js 文档:

A Node.js package is also available in the official repo for Debian Sid (unstable), Jessie (testing) and Wheezy (wheezy-backports) as "nodejs". It only installs a nodejs binary.

因此，如果您只键入 sudo apt-get install nodejs ，它不会安装其他好东西，例如 npm。

您需要输入:

curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs

Optional: install build tools

To compile and install native add-ons from npm you may also need to install build tools:

sudo apt-get install -y build-essential
