很多应用程序(例如npm)可以使用用户环境变量的代理设置。

您可以向您的环境中添加以下变量HTTP_PROXY和HTTPS_PROXY，它们对于每个变量都具有相同的值

http://user:password@proxyAddress:proxyPort

例如，如果你有Windows，你可以添加代理如下:

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。

vim ~ /。npmrc，并添加以下内容。不要忘记添加注册表部分，因为这在很多情况下会导致失败。

proxy=http://<proxy-url>:<port>
https-proxy=https://<proxy-url>:<port>
registry=http://registry.npmjs.org/

对于这个问题，上面有很多答案，但没有一个对我有用。他们都提到要添加http://前缀。所以我也加了进去。都失败了。

它终于工作后，我不小心删除了http://前缀。最终配置如下:

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

我不知道这背后的逻辑，但它奏效了。如果以上答案都不适合你，也许你可以试试这种方法。希望这个对你有用。

这对我来说在Windows中是有效的:

npm config set proxy http://domain%5Cuser:pass@host:port

如果您不在任何域中，请使用:

npm config set proxy http://user:pass@host:port

如果您的密码包含特殊字符，如“，@，:等，请将它们替换为URL编码值。例如“->%22，@->%40，:->%3A。%5C用于字符\。

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!

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
