使用visudo将npm二进制路径添加到sudo路径并编辑“secure_path”

现在“sudo npm”工作了

npm文件应该在/usr/local/bin/npm.如果没有，请在他们的网站上重新安装node.js。这对我来说很管用。

对于MAC用户，以下步骤对我来说是有效的。

如果你得到Error for Brew，下面是你需要在终端中首先输入的命令:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Then run following commands:

$ brew update
$ brew uninstall node
$ brew install node
$ brew postinstall 

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

简单地重新安装。

在RHEL、CentOS和Fedora上

sudo yum remove nodejs npm
sudo dnf remove nodejs npm   [On Fedora 22+ versions]

then

yum -y install nodejs npm
dnf -y install nodejs npm   [On Fedora 22+ versions]

简单! . . node和NPM现在都很好用!

由于我已经使用node.js上可用的.tar文件安装了node.js， 我必须把节点目录的位置放在:

,多达/ .bashrc

使用命令从普通用户切换到root:

sudo -我

然后我必须添加我提取到.bashrc文件的节点路径，如下所示:

然后使用。bashrc刷新

我们走吧。~ / . bashrc

有后

npm: command not found

走了
