我正在尝试升级到最新版本的节点。我在http://davidwalsh.name/upgrade-nodejs上按照说明操作
但当我这样做的时候:
sudo npm install -g n
我得到了错误:
sudo: npm: command not found
NPM没有sudo也能工作。当我这样做的时候:
whereis node
我明白了:
node: /usr/bin/node /usr/lib/node /usr/bin/X11/node /usr/local/node
运行:
which npm
显示:
/usr/local/node/bin/npm
我在https://stackoverflow.com/a/5062718/1246159上尝试了解决方案
但还是得到相同的错误。我还查看了/etc/sudoers文件，相关行是:
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
在我看来这很好。我怎么可能得到NPM工作与sudo命令?
在全局安装包时解决EACCES权限错误
为了尽量减少权限错误的机会，你可以配置npm使用不同的目录。在本例中，您将在主目录中创建和使用隐藏目录。
备份你的电脑。
在命令行中，在你的主目录中，创建一个用于全局安装的目录:
mkdir ~/.npm-global
配置npm使用新的目录路径:
npm config set prefix '~/.npm-global'
在您首选的文本编辑器中，打开或创建~/。配置文件，并添加这一行:
export PATH=~/.npm-global/bin:$PATH
在命令行，更新你的系统变量:
source ~/.profile
要测试您的新配置，请在不使用sudo的情况下全局安装一个包:
npm install -g jshint
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
