我在《Homestead》中也遇到了同样的问题，并尝试了许多方法。 我试过

Sudo apt-get install nodejs

我得到以下错误:

最后我尝试了

Sudo apt-get dist-upgrade

它运行得很好。

root@homestead:/usr/local/bin# npm -v
3.10.10

root@homestead:/usr/local/bin# node -v
v6.13.0

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。

对我来说，上面提到的任何使用Homebrew的方法在macOS上都不起作用。因此，我使用Homebrew卸载了node，并从https://nodejs.org/en/download/下载了node包并安装了它。这招很管用。

我也有同样的问题;下面是修复它的命令:

Sudo ln -s /usr/local/bin/node /usr/bin/node Sudo ln -s /usr/local/lib/node /usr/lib/node Sudo ln -s /usr/local/bin/npm /usr/bin/npm Sudo ln -s /usr/local/bin/node-waf /usr/bin/node-waf

所以，对于那些使用:

NVM和自制

请务必设置节点版本号。对我来说，我的节点版本已不再设置。所以，我检查了我使用的版本

nvm劳拉·舒尔茨

这列出了v16.13.1，所以我设置它使用这个

NVM使用16

一旦我的节点版本设置好，NPM命令又可以工作了

对于CentOS用户，这适用于我:

sudo yum install npm
