如何从Ubuntu 16.04删除Node.js？

复制步骤：

Ubuntu 16.04 Xenial（x86-64）

sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm

我想卸载nodejs，npm并且看到了几则帖子，提示这是最常见的方式：

sudo apt-get purge --auto-remove nodejs

但是，这会产生一个提示，该提示似乎引用了依赖项，如果删除了这些依赖项，听起来好像会引起问题。

什么是“撤销”的最佳方式安装的nodejs和npm？

这是来自的输出sudo apt-get purge nodejs：

从以下输出中可以看出：

sudo apt-get purge nodejs

它只是删除node相关的软件包，即相关的软件包，仅此而已。

另一方面，当您这样做时：

sudo apt-get purge --auto-remove nodejs

它一定在做：

sudo apt-get purge nodejs
sudo apt-get autoremove

和去除的gyp，linux-headers-4.4.0-18-generic等包实际上是由触发的autoremove，因为他们是一个安装的依赖，不再受任何已安装的程序包所需，大概是因为主包已被删除。

因此，在这种情况下运行是完全可以的：

sudo apt-get purge --auto-remove nodejs

如果您过于偏执，可以分两个步骤进行：首先purge nodejs：

sudo apt-get purge nodejs

然后删除孤立的依赖项（直到现在，如果有的话）：

sudo apt-get autoremove

要从Ubuntu中删除node js，npm和node_modules，您还需要删除在Ubuntu中不同位置的容器。这些可能是：

/usr/local/bin/npm，/usr/local/share/man/man1/node，/usr/local/lib/dtrace/node.d，~/.npm ~/.node-gyp，/opt/local/bin/node，opt/local/include/node，/opt/local/lib/node_modules

我成功做到了。所以我要分享整个程序

您需要按照http://amcositsupport.blogspot.in/2016/07/to-completely-uninstall-node-js-from.html中的步骤进行操作

sudo apt-get remove nodejs

sudo apt-get remove npm

然后转到/etc/apt/sources.list.d并删除所有节点列表（如果有）。然后做一个

sudo apt-get update

检查主文件夹中是否有任何.npm或.node文件夹，并将其删除。

如果您输入

which node

您可以看到节点的位置。尝试which nodejs和which npm太。

我建议使用节点版本管理器（NVM）安装节点。那为我节省了很多头痛。因为您可以使用nvm安装nodejs和npm而不使用sudo。
