我正在遵循https://github.com/nodesource/distributions在Debian上安装Nodejsv11.x。遵循这两个指示后，Nodejs似乎安装正确，并且nodejs -v返回v4.8.2。
但是似乎未安装npm。 whereis npm不返回任何内容，我可以肯定地说磁盘上没有安装npm。
我在下面的命令curl -sL https://deb.nodesource.com/setup_11.x | bash -之后粘贴了控制台日志：

Error executing command, exiting
我的猜测是，由于apt-get抛出错误，安装程序脚本在过程中停止。但是，即使是那样，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，以使其积极退出。
如果答案与apt-get有关，并且在该论坛上不在主题范围内，也许可以将其迁移到askubuntu？
答案 0 :(得分：2)
好吧，首先让我们解决关于存储库的错误。
此行告诉您问题所在。

您是否遵循了freecad页面上的主要安装说明？参见https://launchpad.net/~freecad-maintainers/+archive/ubuntu/freecad-stable
然后单击“签名”键-这是什么？
关于节点问题，请尝试更新节点： https://www.hostingadvice.com/how-to/update-node-js-latest-version/
另外，尝试sudo apt-get install npm
答案 1 :(得分：1)
尝试修复存储库问题会产生奇怪的python错误，这可能与我在系统中同时安装了python 2.7和3有关，但我不确定。
我最终要做的只是暂时从/etc/apt/sources.list.d中删除有问题的存储库，然后再次运行curl脚本。这样可以使脚本运行无任何错误，然后，命令apt install -y nodejs将安装正确的版本以及npm。
问题似乎是debian的默认存储库也有一个nodejs封装，没有npm。并且由于apt-get update错误，安装脚本过早退出。修复该错误即可完成工作。
