发布安装dart-web-components失败

Question

在dart-web-component上运行pub install会出现错误：

Pub install fail, HttpParserException: Connection closed before full header was received

/dart-web-components/build.dart --changed=packages\args\args.dart --changed=packages\args\src\utils.dart --changed=packages\logging\...
Failed with error code 255
Unable to open file: C:/dartapps/dart-web-components/packages/web_components/component_build.dart'file:///C:/dartapps/dart-web-components/build.dart': Error: line 8 pos 1: library handler failed

导入'package:web_components/component_build.dart'；^

在build.dart文件中有一个字符串

import 'package:web_components/component_build.dart';

编辑器显示错误

Cannot find referenced source: package:web_components/component_build.dart    

component_build.dart包含错误

Cannot find referenced source: package:args/args.dart
Cannot find referenced source: package:web_components/dwc.dart

我解决了这个问题。缓存文件夹(Pub)似乎已损坏。

我已删除文件夹缓存：

C:\Users\\AppData\Roaming\Pub

然后我从命令行运行pub install，它就可以工作了。

我的操作系统是Windows 7。

好的，现在看看你的输出：

Pub install fail, HttpParserException: Connection closed before full header was received

这才是真正的问题。

/dart-web-components/build.dart --changed=packages\args\args.dart --changed=packages\args\src\utils.dart --changed=packages\logging\...
Failed with error code 255
Unable to open file: C:/dartapps/dart-web-components/packages/web_components/component_build.dart'file:///C:/dartapps/dart-web-components/build.dart': Error: line 8 pos 1: library handler failed

这些仅仅是由第一个问题引起的转移注意力的问题。

我看到你用的是Windows。有一个已知的问题，其中HTTP内容有一些间歇性的非确定性故障。我还在调查，但很难追踪到。

你每次尝试的时候都会得到这个错误吗？你做了多少次尝试？

很抱歉给您添了麻烦。

我试过很多次了。现在，我将dart-web-component放到默认的包根目录中。Pub install now生成

Pub install fail, Package "html5lib" doesn't have a pubspec.yaml file.

但是，编辑器会显示相同的错误

Cannot find referenced source: package:web_components/component_build.dart
Cannot find referenced source: package:args/args.dart

等等。在几乎每个*.dart文件中
