node.js - Debian - Nodejs 已安装，但 npm 未安装

Question

我正在按照 https://github.com/nodesource/distributions 在 Debian 上安装 Nodejs v11.x。按照这两条说明进行操作后，Nodejs 似乎安装良好，并且 nodejs -v 返回 v4.8.2。

但是npm好像没有安装。 whereis npm 没有返回任何内容，我相当确定我的磁盘上没有安装 npm。

我已在命令 curl -sL https://deb.nodesource.com/setup_11.x | 之后粘贴控制台日志bash - 如下:

Error executing command, exiting

我的猜测是安装程序脚本在此过程中停止，因为 apt-get 抛出错误。但即使是这样，我也不知道如何解决这个问题。我不想删除 freecad 和 java 的存储库来避免主动退出。

如果答案与 apt-get 有关并且与本论坛无关，也许可以将其迁移到 askubuntu？

Answer 1

好吧，首先让我们解决您看到的有关存储库的错误。

这一行告诉你问题所在。

您是否遵循了 freecad 页面上的关键安装说明？请参阅https://launchpad.net/~freecad-maintainers/+archive/ubuntu/freecad-stable

然后单击签名 key - 这是什么？

关于Node问题，尝试更新Node: https://www.hostingadvice.com/how-to/update-node-js-latest-version/

另外，尝试 sudo apt-get install npm
