我的解决办法是登录为根，现在我不必再使用sudo

su root

对于CentOS用户，这适用于我:

sudo yum install npm

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

我用……解决了这个问题

apt-get install npm2deb

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。

如果你用nvm安装node/npm，在使用任何一个包之前都必须运行nvm环境配置文件。

这通常在~/.nvm/nvm.sh中找到。

要自动运行，包括:

source ~/.nvm/nvm.sh

在您的用户的.bash_profile文件中

如果希望对该用户使用sudo，请确保包含-i参数以使sudo设置用户环境。如

sudo -iu jenkins npm install grunt-cli
