我检查了是否安装了节点：

$ which nodejs
/usr/bin/nodejs
$ which node
/usr/bin/node

从这里我有点迷路。 有人知道从这里做什么吗？

Answer 1

我建议您重新安装Nodejs，因为

npm：依赖于：nodejs，但是不会被安装

错误中指出未安装nodejs（未正确安装）。

我建议您从https://nodejs.org/en/download/下载源代码 node-v6.9.1.tar.gz

然后

tar -zxvf  node-v6.9.1.tar.gz

cd node-v6.9.1

./configure

make

sudo make install

通过以上步骤， Nodejs和NPM将安装在您的计算机上。

您可以在命令提示符下使用node -v和npm -v验证安装。

最后，我通过安装nvm （将版本号调整为当前版本）解决了该问题：

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash
export NVM_DIR="$HOME/.nvm"  # OR LOG OUT AND BACK IN AGAIN

然后，我使用nvm安装了最新版本的node，该节点也安装了npm。

nvm install node

我希望这可以帮助遇到相同问题的其他人。

Answer 3

请参阅节点包管理器已损坏

您可以执行以下操作

sudo apt-get remove nodejs npm ## remove existing nodejs and npm packages
sudo apt-get install curl  
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs  

这适用于我的Ubuntu 16.04.2
