我必须这么做

sudo apt-get install npm

这对我很管用。

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。

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

而不是重新安装节点，这似乎是公认的解决方案，问题是没有权限到nodejs文件夹/usr/local。 输入如下命令sudo chmod -R 777 /usr/local/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。

我用……解决了这个问题

apt-get install npm2deb
