npm install hangs
提问by user1090227
This is my package.json:
这是我的package.json：

"name": "my-example-app",
"version": "0.1.0",
"dependencies": {
"request": "*",
"nano": "3.3.x",

I had the same problem. The reason - wrong proxy was configured and because of that npm was unable to download packages.
我有同样的问题。原因 - 配置了错误的代理，因此 npm 无法下载软件包。
So your best bet is to the see the output of
所以你最好的选择是查看输出
$ npm install --verbose
and identify the problem. If you have never configured proxy, then possible causes can be
并找出问题所在。如果您从未配置过代理，那么可能的原因可能是
- Very outdated npm version.
- Some problem with your internet connection.
- Permissions are not sufficient for npm to modify files.
- 非常过时的 npm 版本。
- 您的互联网连接有问题。
- 权限不足以让 npm 修改文件。

问题出在我的网络驱动程序上。我只需要重新启动，滞后就消失了。

You can try deleting package-lock.jsonand running npm installafterwards.
This worked for me.
您可以尝试删除package-lock.json并稍后运行npm install。这对我有用。

I am behind a corporate proxy, so I usually use an intermediate proxy to enable NTLM authentication.
我支持公司代理，因此我通常使用中间代理来启用 NTLM 身份验证。
I had hangs problem with npm install when using CNTLM proxy. With NTLM-APS (a similar proxy) the hangs were gone.
使用 CNTLM 代理时，我遇到了 npm install 挂起问题。使用 NTLM-APS（类似的代理），挂起就消失了。

This method is working for me when npm blocks in installation Package for IONIC installation and ReactNative and another package npm.
当 npm 在用于 IONIC 安装和 ReactNative 的安装包和另一个包 npm 中阻塞时，此方法对我有用。
You can change temporary:
您可以临时更改：
npm config set prefix C:\Users\[username]\AppData\Roaming\npm\node_modules2
npm config set prefix C:\Users\[username]\AppData\Roaming\npm\node_modules2
Change the path in environment variables. Set:
C:\Users[username]\AppData\Roaming\npm\node_modules2
Run the command to install your package.
Open file explorer, copy the link:
C:\Users[username]\AppData\Roaming\npm\node_modules
ok file yourpackage.CMD created another folder Created "node_modules2" in node_modules and contain your package folder.
Copy your package file CMD to parent folder "npm".
Copy your package folder to parent folder "node_modules".
Now run:
npm config set prefix C:\Users\[username]\AppData\Roaming\npmChange the path in environment variables. Set:
C:\Users[username]\AppData\Roaming\npm
更改环境变量中的路径。放：
C:\Users[用户名]\AppData\Roaming\npm\node_modules2
运行命令来安装你的包。
打开文件资源管理器，复制链接：
C:\Users[用户名]\AppData\Roaming\npm\node_modules
ok 文件 yourpackage.CMD 创建了另一个文件夹在 node_modules 中创建了“node_modules2”并包含您的包文件夹。
将您的包文件 CMD 复制到父文件夹"npm"。
将您的包文件夹复制到父文件夹"node_modules"。
现在运行：
npm config set prefix C:\Users\[username]\AppData\Roaming\npm更改环境变量中的路径。放：
C:\Users[用户名]\AppData\Roaming\npm
Now the package is working correctly with the command line.
现在该软件包可以在命令行中正常工作。

The registry(https://registry.npmjs.org/cordova) was blocked by our firewall. Unblocking it fixed the issue.
注册表 ( https://registry.npmjs.org/cordova) 被我们的防火墙阻止。取消阻止它解决了这个问题。

Incase its useful to others, the following is what worked for me:
如果对其他人有用，以下对我有用：
On my machine, although npm proxy was set correctly, npm installwaits forever doing something like sill extract. Re-trying npm installwaits forever on the same package again and again.
在我的机器上，尽管 npm 代理设置正确，但npm install会永远等待执行诸如 sill extract 之类的操作。重试npm install一次又一次地等待同一个包。
After waiting for a long timeout, npm installprinted an error message implying that gitwas trying to fetch something.
等待很长时间后，npm install打印了一条错误消息，暗示git正在尝试获取某些内容。
The problem vanished after configuring gitproxy using the below command:
使用以下命令配置gitproxy后问题消失：
git config --global http.proxy https://proxy-server:port
Note the httpsin the valueof http.proxywithout which the configuration did not take effect. Proxy server settings (http / https / port) might vary for users; hence its worth spending a bit of time experimenting with npmand gitproxy server settings.
注意https在值中http.proxy没有它的配置并没有生效。代理服务器设置（http / https / 端口）可能因用户而异；因此值得花一些时间来试验npm和git代理服务器设置。

When your ssh key is password protected run ssh-add. npm probably hangs somewhere asking for your password.
当您的 ssh 密钥受密码保护时，运行ssh-add. npm 可能挂在某个地方要求您输入密码。
