Answer 1

npm与nodejs一起安装。如果您安装了节点，那么您也有npm。

运行node -v检查节点是否已安装，然后运行npm -v为npm执行相同操作。

如果未安装nodejs，请在此处查看安装说明： https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions

6.x是当前的稳定分支。

通常，要运行擦除现有节点/ npm安装并从头开始安装，请运行：

sudo apt remove --purge nodejs node npm
sudo apt clean
sudo apt autoclean
sudo apt install -f
sudo apt autoremove

安装node和npm的最佳和最简单的方法是通过nvm（节点版本管理器）。

1. 运行以下代码以安装nvm

   curl -o- | bash的

2.然后运行

nvm install node

npm将与节点

一起安装

此方法将是npm和节点安装的最简单，最安全的方法。

要安装特定节点和npm，您可以像下面这样执行：

nvm install v6.11.3

希望这有帮助。
