Question

我使用以下命令安装了nodejs：

    curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
    sudo apt-get install -y nodejs

之后我检查了它的版本，它显示： v7.10.1 但是当我使用npm -v检查npm版本时，它显示错误

/usr/local/lib/node_modules/npm/node_modules/npm-package-arg/npa.js:6
let url

用于安装npm我用过命令：sudo apt-get install npm，它显示如下

sudo apt-get install npm

Answer 1

试试这个

更新apt-get update 获取安装脚本并将其传递给执行：

curl -sL https://deb.nodesource.com/setup_7.x | bash

并安装节点apt-get install nodejs 确认成功node -v npm自动安装 npm -v

注意 - 不要使用apt-get install -y nodejs而是使用apt-get install nodejs，它会自动安装指定的节点版本和npm。

我希望这能解决你的问题。我已完成上述步骤并成功更新，没有任何问题。如果您有任何问题或疑虑，请告诉我。

Answer 2

当您尝试使用apt-get安装软件包时，取决于其他软件包，apt-get仅尝试安装最重要的软件包，而apt-get不安装依赖项。因此，还有另一个像apt-get这样的软件包管理器，称为aptitude，它安装软件包和依赖项。因此，您可以执行以下操作：

sudo aptitude install npm

我想在ubuntu中安装nodejs，我安装了nodejs并检查了它的版本，它运行正常但是npm没有正确安装
