虽然已经有很多好的建议，但对于我的环境(Windows 7，使用PowerShell)和最后一个可用的node.js版本(v8.1.2)，上述所有建议都不起作用，除非我遵循brunowego设置。

检查你的设置:

npm config list

代理背后的设置:

npm config set registry http://registry.npmjs.org/
npm config set http-proxy http://username:password@ip:port
npm config set https-proxy http://username:password@ip:port
npm config set proxy http://username:password@ip:port
npm set strict-ssl false

希望这能节省别人的时间

在我的情况下，我忘记在配置文件中设置“http://”(可以在C: \Users \ [USERNAME] \ .npmrc中找到)代理地址。所以我们不需要

proxy=http://[IPADDRESS]:[PORTNUMBER]
https-proxy=http://[IPADDRESS]:[PORTNUMBER]

我有

proxy=[IPADDRESS]:[PORTNUMBER]
https-proxy=[IPADDRESS]:[PORTNUMBER]

这当然没有工作，但错误消息也没有多大帮助…

如果有疑问，试试所有这些命令，就像我做的那样:

npm config set registry http://registry.npmjs.org/
npm config set proxy http://myusername:mypassword@proxy.us.somecompany:8080
npm config set https-proxy http://myusername:mypassword@proxy.us.somecompany:8080
npm config set strict-ssl false
set HTTPS_PROXY=http://myusername:mypassword@proxy.us.somecompany:8080
set HTTP_PROXY=http://myusername:mypassword@proxy.us.somecompany:8080
export HTTPS_PROXY=http://myusername:mypassword@proxy.us.somecompany:8080
export HTTP_PROXY=http://myusername:mypassword@proxy.us.somecompany:8080
export http_proxy=http://myusername:mypassword@proxy.us.somecompany:8080

npm --proxy http://myusername:mypassword@proxy.us.somecompany:8080 \
--without-ssl --insecure -g install

更新

将您的设置放入~/。Bashrc或~/。Bash_profile，这样你就不必担心你的设置每次打开一个新的终端窗口!

如果你的公司像我的公司一样，我必须经常更改密码。因此，我在~/中添加了以下内容。Bashrc或~/。这样每当我打开一个终端，我就知道我的npm是最新的!

Simply paste the following code at the bottom of your ~/.bashrc file: ###################### # User Variables (Edit These!) ###################### username="myusername" password="mypassword" proxy="mycompany:8080" ###################### # Environement Variables # (npm does use these variables, and they are vital to lots of applications) ###################### export HTTPS_PROXY="http://$username:$password@$proxy" export HTTP_PROXY="http://$username:$password@$proxy" export http_proxy="http://$username:$password@$proxy" export https_proxy="http://$username:$password@$proxy" export all_proxy="http://$username:$password@$proxy" export ftp_proxy="http://$username:$password@$proxy" export dns_proxy="http://$username:$password@$proxy" export rsync_proxy="http://$username:$password@$proxy" export no_proxy="127.0.0.10/8, localhost, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16" ###################### # npm Settings ###################### npm config set registry http://registry.npmjs.org/ npm config set proxy "http://$username:$password@$proxy" npm config set https-proxy "http://$username:$password@$proxy" npm config set strict-ssl false echo "registry=http://registry.npmjs.org/" > ~/.npmrc echo "proxy=http://$username:$password@$proxy" >> ~/.npmrc echo "strict-ssl=false" >> ~/.npmrc echo "http-proxy=http://$username:$password@$proxy" >> ~/.npmrc echo "http_proxy=http://$username:$password@$proxy" >> ~/.npmrc echo "https_proxy=http://$username:$password@$proxy" >> ~/.npmrc echo "https-proxy=http://$username:$password@$proxy" >> ~/.npmrc ###################### # WGET SETTINGS # (Bonus Settings! Not required for npm to work, but needed for lots of other programs) ###################### echo "https_proxy = http://$username:$password@$proxy/" > ~/.wgetrc echo "http_proxy = http://$username:$password@$proxy/" >> ~/.wgetrc echo "ftp_proxy = http://$username:$password@$proxy/" >> ~/.wgetrc echo "use_proxy = on" >> ~/.wgetrc ###################### # CURL SETTINGS # (Bonus Settings! Not required for npm to work, but needed for lots of other programs) ###################### echo "proxy=http://$username:$password@$proxy" > ~/.curlrc Then edit the "username", "password", and "proxy" fields in the code you pasted. Open a new terminal Check your settings by running npm config list and cat ~/.npmrc Try to install your module using npm install __, or npm --without-ssl --insecure install __, or override your proxy settings by using npm --without-ssl --insecure --proxy http://username:password@proxy:8080 install __. If you want the module to be available globally, add option -g

你尝试过命令行选项而不是.npmrc文件吗?

我认为类似于npm——proxy http://proxy-server:8080/ install {package-name}的东西对我有用。

我还看到了以下内容: NPM配置设置代理http://proxy-server:8080/

我尝试了所有这些选择，但出于某种原因，我的代理人没有任何选择。然后，出于绝望，我在Git Bash shell中随机尝试了curl，它起作用了。

清除使用的所有代理选项

npm config rm proxy
npm config rm https-proxy

然后在我的Git Bash shell中运行npm install，效果非常好。我不知道如何正确设置代理和Windows cmd提示符，但它工作。

Windows系统

尝试删除代理和注册表设置(如果已经设置)，并通过命令行设置环境变量

SET HTTP_PROXY=http://username:password@domain:port
SET HTTPS_PROXY=http://username:password@domain:port

然后尝试运行NPM install。这样，你就不用在.npmrc中设置代理了，但是对于那个会话，它是可以工作的。
