而不是重新安装节点，这似乎是公认的解决方案，问题是没有权限到nodejs文件夹/usr/local。 输入如下命令sudo chmod -R 777 /usr/local/nodejs/

I had the same issue,the reason for it was npm package manager was not installed while installing node. This was caused because of the following mistake: In the installation process there is a step called "Custom Setup", here you have the option to choose one of the following: 1) Node.js runtime (This is selected by default). 2) npm package manager 3) Online documentation shortcuts. 4) Add to Path. If you proceed as it is npm package manager will not be installed and hence you will get the error.

解决方案: 当你得到这些选项时，选择npm包管理器。 这对我很管用。

在情况下可能是有用的任何人使用rh-*包，这为我工作:

sudo ln -s /opt/rh/rh-nodejs8/root/usr/bin/npm /usr/local/bin/npm

在macOS上，这对我来说很管用:

brew reinstall node

我的解决办法是登录为根，现在我不必再使用sudo

su root
