3 个解决方案

#1

You might try to run npm cache clean. I had similar issues and this solved it for me.

您可以尝试运行npm缓存清理。我也遇到过类似的问题，这就帮我解决了。

#2

The first error says that you do not have permission to execute chown on the file package.json. I'm assuming npm is trying to change ownership of that file to do it's thing.

第一个错误表示您没有权限在file package.json上执行chown。我假设npm试图改变文件的所有权来做它的事情。

npm ERR! Error: EPERM, chown '/misc/htdocs/hello-world/node_modules/cookie signature/package.json'

In short, it looks like you want to execute npm install with sudo:

简而言之，看起来您希望使用sudo执行npm安装:

sudo npm install dependency-name

Or as root if you don't have sudo:

或者作为根，如果你没有sudo:

su
# type your root password at the prompt
npm install dependency-name

#3

Try this:

试试这个:

sudo npm cache clean -f 
sudo npm install -g n 
sudo n stable

Actually what it does is, it updates your npm.

实际上它所做的是更新npm。
