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

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

其他回答

对于CentOS用户,这适用于我:

sudo yum install npm

**编辑**

警告!做chmod 777是一个相当激进的解决方案。先试试这些,一次一个,其中一个管用就停止:

$ sudo chmod -R 777 /usr/local/lib/node_modules/npm $ sudo chmod -R 777 /usr/local/lib/node_modules . sh $ sudo chmod g+w /usr/local/lib $ sudo chmod g+rwx /usr/local/lib


$ brew postinstall节点是我唯一会遇到问题的安装部分

Permission denied - /usr/local/lib/node_modules/npm/.github

So I

// !! READ EDIT ABOVE BEFORE RUNNING THIS CODE !!
$ sudo chmod -R 777 /usr/local/lib
$ brew postinstall node

中提琴,NPM现在被连接了

$ npm -v
3.10.10

额外的

如果你在lib上使用-R 777,我的建议是将嵌套文件和目录设置为默认设置:

$ find /usr/local/lib -type f -print -exec chmod 644 {} \; $ find /usr/local/lib -type d -print -exec chmod 755 {} \; $ chmod /usr/local/lib 755

我的解决办法是登录为根,现在我不必再使用sudo

su root

如果您使用的是linux,请删除存在于/usr/lib中的node_modules文件夹

sudo rm -rf node-modules

然后使用curl重新安装节点:

sudo apt-get update
sudo apt install curl build-essential
curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash -
sudo apt install -y nodejs

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。
