我正在尝试在 Ubuntu 上安装 npm。首先我检查 NPM 是否安装：
jmlopez@desarrollo:/usr/share$ npm -v
Command 'npm' not found, but can be installed with:
sudo apt install npm
然后我尝试安装它，但我得到：
jmlopez@desarrollo:/usr/share$ sudo apt install npm
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
npm is already the newest version (8.5.1~ds-1).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libnode-dev : Depends: libssl-dev but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
我也尝试卸载nodejs，但它抛出了这个：
jmlopez@desarrollo:/usr/share$ sudo apt remove nodejs
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.

安装的nodejs版本是：
jmlopez@desarrollo:/usr/share$ nodejs -v
v12.22.9
这些问题有关联吗？有什么想法可以解决它们吗？
提前非常感谢您！！
要在 Ubuntu 上安装 Node Package Manager，请尝试以下说明。
sudo apt update
sudo apt install nodejs
node --version
如果显示Node版本说明安装成功
要验证 npm 版本，请执行以下命令：
npm --version
这里的替代方案：
# installs NVM (Node Version Manager)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
# download and install Node.js
nvm install 20
# verifies the right Node.js version is in the environment
node -v # should print `v20.12.2`
# verifies the right NPM version is in the environment
npm -v # should print `10.5.0`
