javascript - curl获取的文件如何清除

Question

我正在开发 Debian Stable Linux(定期更新)。我从存储库安装了 nodejs，但没有获得 node 和 npm 命令。因此，我尝试使用此页面中的说明:https://www.npmjs.com/package/node-compile/tutorial :

我运行了这个命令:

$ curl -sL https://deb.nodesource.com/setup | sudo -E bash -

虽然我收到了一条“已弃用”的消息，但我还是允许它运行。然后我跑了:

$ sudo apt-get install -y nodejs

但是，node 和 js 命令仍然不可用。然后我安装了 nodejs-dev 但仍然没有成功。如上链接所示，node -v 和 npm -v 仍然不起作用。

因此，我删除(清除)了 nodejs 和 nodejs-dev 包。我有两个问题:

1. 上面的 curl 命令是否有任何我需要撤销的更改？

2. 如何获取node和npm命令？

感谢您的帮助。

编辑:

以下是用于安装的命令的输出:

$ curl -sL https://deb.nodesource.com/setup | sudo -E bash -

                           SCRIPT DEPRECATION WARNING                         

  This script, located at https://deb.nodesource.com/setup, used to
  install Node.js v0.10, is being deprecated and will eventually be made
  inactive.

  You should use the script that corresponds to the version of Node.js you
  wish to install. e.g.

   * https://deb.nodesource.com/setup_4.x — Node.js v4 LTS "Argon" (recommended)
   * https://deb.nodesource.com/setup_6.x — Node.js v6 Current

  Please see https://github.com/nodejs/LTS/ for details about which version
  may be appropriate for you.

                       NODE.JS v0.10 DEPRECATION WARNING                      

  Node.js v0.10 will cease to be actively supported in October 2016.

  This means you will not continue to receive security or critical stability
  updates for this version of Node.js beyond that time.

  You should begin migration to a newer version of Node.js as soon as
  possible. Use the installation script that corresponds to the version of
  Node.js you wish to install. e.g.

   * https://deb.nodesource.com/setup_4.x — Node.js v4 LTS "Argon" (recommended)
   * https://deb.nodesource.com/setup_6.x — Node.js v6 Current

  Please see https://github.com/nodejs/LTS/ for details about which version
  may be appropriate for you.

Answer 1

curl -sL https://deb.nodesource.com/setup | sudo -E bash -

它下载一个 bash 脚本并直接以 sudo 权限执行。这可能非常危险。不要这样做。

取而代之的是 curl -O https://deb.nodesource.com/setup只需通过 less setup 检查脚本。如果没问题，执行 sudo setup

回答您的第一个问题。

setup 是一个包安装脚本。它将一些包添加到 sources.list 并安装一些 gpg key 。没有必要撤销它所做的更改。
