Question

我正在使用npm安装Angular CLI，因此我可以将Angular 4用于某些项目。但是，我得到了400 Bad Request错误。有人也遇到过这个问题并得到了解决方案吗？我已经尝试过搜索一些与我的问题有关但不幸看到一个。

命令：

npm config set proxy="myproxy.com:1234"
npm config set proxy-http="http://registry.npmjs.org/"
npm install -g @angular/cli

好的伙计们，我刚才用这个设置删除了400个错误：

npm config set proxy="http://username:password@proxyserverpac:proxyport/"
npm config set https-proxy="http://username:password@proxyserverpac:proxyport/"
npm config set http-proxy="http://username:password@proxyserverpac:proxyport/"
npm config set registry="http://registry.npmjs.org/"

但现在我遇到了这个错误：

有人可以指导我如何克服这个问题吗？

编辑3：

现在已经解决了。

下面没有一个答案/评论解决了我的问题。

但是，感谢您在这里的所有输入。我很感激。

解决方案：我认为使用公司的代理服务器可以解决这个问题，但我没有了解到小提琴手是唯一的答案。我使用它并在npm中将代理设置为“http://localhost:8888/”并且安装完成。

Answer 1

尝试清理缓存

$ npm cache clean

然后再次卸载/安装它通常是一个好主意。可以把它想象成再次关闭电脑。

$ npm uninstall -g @angular/cli
$ npm install -g @angular/cli

Answer 2

如果您需要代理来访问Internet，则必须确保为http和https指定协议（例如http / https）：

npm config set proxy="http://myproxy.com:1234"

此外，您很有可能需要为https提供相同的代理：

npm config set https-proxy="http://myproxy.com:1234"

此外，运行npm config set strict-ssl false以规避任何可能的证书错误。

Answer 3

1 .open命令提示符

2 。运行命令“ npm config edit”（打开一个文件）

3 。已删除身份验证部分“ strict-ssl = true和3-4行” 并保存文件

然后再次安装角度cli
