I've tried almost all methods posted in various forums like stackoverflow, github-issues etc.. but nothing seemed to work. Here are the commands I've executed in order which I encourage you to try because it worked for many people (but not me):
我已经尝试了在各种论坛（如 stackoverflow、github-issues 等）中发布的几乎所有方法，但似乎没有任何效果。以下是我按顺序执行的命令，我鼓励您尝试这些命令，因为它适用于许多人（但不适用于我）：
npm config rm proxynpm config rm https-proxynpm config set https-proxy https://username:[email protected]:6050npm config set proxy http://username:[email protected]:6050npm config set registry http://registry.npmjs.org/
npm config rm proxynpm config rm https-proxynpm config set https-proxy https://username:[email protected]:6050npm config set proxy http://username:[email protected]:6050npm config set registry http://registry.npmjs.org/
And then when trying to install the package npm install -g express- it failed.
然后在尝试安装软件包时npm install -g express- 它失败了。
However, when I tried to run npm install npm@latest -git miraculouslyexecuted and installed fine!
Then running npm install -g expressagain worked perfectly fine too.
但是，当我尝试运行npm install npm@latest -g它时，它奇迹般地执行并安装得很好！然后npm install -g express再次运行也完全正常。
TL;DR: updating npm to the latest version solved the issue (currently 6.0.1)
TL;DR：将 npm 更新到最新版本解决了这个问题（目前是 6.0.1）

I solved this problem by setting the proxy property of config.
我通过设置 config 的 proxy 属性解决了这个问题。
The most likely reason you might be facing this problem is if you are behind a proxy.
您可能面临此问题的最可能原因是您是否使用代理。
You may follow the following steps to solve the issue
您可以按照以下步骤解决问题
Type:
类型：
npm config get proxy
If you get null. It means the proxy is not set.
如果你得到空值。这意味着未设置代理。
Go to Internet Explorer->Tools->Internet Options-> LAN Settings Here you would find your proxy address and port under proxy server. If you have your username and password then do the following
转到 Internet Explorer->工具->Internet 选项-> LAN 设置 在这里您可以在代理服务器下找到您的代理地址和端口。如果您有用户名和密码，请执行以下操作
npm config set proxy http://your-username:your-password@Proxy-address:port-number
After this you can use npm install.
在此之后，您可以使用 npm install。
