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

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。

我的解决办法是登录为根，现在我不必再使用sudo

su root

为了在sudo权限下全局安装npm包，/usr/bin/npm应该是可用的。如果npm存在于其他目录，创建一个像这样的软链接:

sudo ln -s /usr/local/bin/npm /usr/bin/npm

它适用于Fedora 25、node8.0.0和npm5.0.0

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。

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
