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?


当前回答

安装node.js并简单运行

npm install -g bower

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

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。

如果你已经下载了节点包并提取到/opt这样的地方,你可以简单地在/usr/local/bin中创建符号链接。

/usr/local/bin/npm -> /opt/node-v4.6.0-linux-x64/bin/npm
/usr/local/bin/node -> /opt/node-v4.6.0-linux-x64/bin/node

你可以通过为npm和node创建符号链接来解决这个问题,这是快速而简单的:

sudo ln -s $(which npm) /usr/local/bin/npm
sudo ln -s $(which node) /usr/local/bin/node

我使用which来获取位置,然后将其作为变量传递给命令,例如$(npm)。

我也为node创建了一个符号链接,因为npm依赖于 节点。

然后你就可以:

sudo npm -v

不需要重新安装节点或在整个目录上使用chmod。

在我的例子中,由于某种原因,在安装了一些python模块后,我突然开始收到消息,说node没有安装或没有被识别为命令。 经过检查,我的路径被注册在.bashrc中。 所以我找到了那个文件,一切都恢复正常了。
