在配置代理之后，无法npm安装Angular cli

Question

我正在尝试使用npm安装在Windows 10中下载Angular。由于我使用公司代理，我将代理配置为username：password@server：端口

然而，我在运行时遇到了这个问题

npm ERR! code E407 npm ERR! 407 Proxy Authorization Required: @angular/cli@latest

调试日志如下：

你知道是什么导致了这个问题吗？谢谢

Answer 1

此配置对我有效：

方法1(命令行)：

npm config set proxy http://user:password@domain_proxy:port/
npm config set https-proxy http://user:password@domain_proxy:port
be careful the url should be encoded. for example this password 01xx!tr should be introduced as 01xx%21tr. use this site to encode your url https://www.url-encode-decode.com/
example:
user/password => user1/01xx!tr
domain:port of the proxy => mydomain.org:8000
=> in that case :
npm config set proxy http://user1:[e-mail]:8000/
npm config set https-proxy http://user1:[e-mail]:8000

方法2(编辑节点目录文件)：

the method 2 is easier because we will not be botherd with encoding the urls
1- edit node configuration file (in windows it's located in %USERPROFILE%.npmrc, example C:UsersJack.npmrc)
2- add these lines
proxy=http://user:password@domain_proxy:port/
https-proxy=https-proxy http://user:passwor`enter code here`d@domain_proxy:port
example :
if the :
user/password => user1/01xx!tr
domain:port of the proxy => mydomain.org:8000
=> the configuration file should be look like this:
proxy=http://user1:01xx![e-mail]:8000/
https-proxy=http://user1:01xx![e-mail]:8000

Answer 2

解决了它。在我花了一点时间研究代理问题后，发现我的错误是设置了3个代理变量：proxy、http proxyttps proxy。

(注意：我在stackoverflow上读到我应该设置http proxy，但这是错误的)

删除http代理为我解决了这个问题。

设置npm-proxy和npm-https_proxy是正确的，如下所示：

npm config set proxy http://user:[e-mail]:port/
npm config set https-proxy http://user:[e-mail]:port/

Answer 3

尝试将npm注册表的URL设置为http而不是https。你可以看看这个答案。

Answer 4

如果您已经配置了Proxy和Still，则无法使用npm命令进行安装。您可以尝试以下命令。你似乎需要清理一些东西——这将解决问题。

npm cache verify

Answer 5

这些步骤对我有效

编辑.npmrc文件在行下方添加

proxy=http://username:password@proxyaddress:portno
https-proxy=http://username:password@proxyaddress:portno

Answer 6

对我有用的东西如下，问题：在"C:\Users*用户名*.npmrc"中定义的注册表是错误的。需要更新npm配置注册表。

步骤1解决方案：从"C:\Users*用户名*.npmrc"文件中删除了注册表项。

步骤2在步骤1之后，我得到了以下错误

npm install-g@angular/clinpm WARN注册表的意外警告https://registry.npmjs.org/:杂项警告SELF_SIGNED_CERT_IN_CHAIN：请求https://registry.npmjs.org/@angular%2fcli失败，原因：证书链中的自签名证书npm WARN注册表使用来自https://registry.npmjs.org/由于在重新验证过程中出现请求错误。

问题：npm维护者于2月27日宣布，npm的自签名证书不再存在：今天一整天，一群用户在安装和发布软件包时收到了"SELFSIGNEDCERTINCHAIN"错误。npm不再支持其自签名证书。然而，推荐的修复程序对我来说失败了。

解决方案：打开命令提示符，然后运行以下命令。SETLOCALSET npm_config_strict-sl=falsenpm安装npm-g--ca=nullnpm—版本端局部

步骤3现在>npm install-g@angular/cli运行一切正常。

要在办公室中配置代理，

npm config set proxy http://user:[e-mail]:port/
npm config set https-proxy http://user:[e-mail]:port/
