Question

在dart-web-components上运行pub install会出错：

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

import'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。似乎Cache文件夹（Pub）已损坏。

我删除了文件夹Cache：

C：\用户\＆LT; 用户名＆GT; \应用程序数据\漫游\酒吧

然后我从命令行运行pub install并且它可以工作。

我的操作系统是Windows 7。

好的，所以看看你的输出：

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

这是真正的问题。

/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

这些只是第一个问题造成的红色鲱鱼。

我看到你在Windows上。存在一个已知问题，即HTTP内容具有一些间歇性的非确定性故障。我还在调查，但很难追查。

每次尝试都会出现此错误吗？你做了多少次尝试？

抱歉这里有麻烦。

我多次尝试过。我现在将dart-web-components放到默认的package-root目录中。 Pub install现在产生

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

然而，编辑器显示相同的错误

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

等。几乎每个* .dart文件

Answer 4

在pubscpec.yams

中添加了此内容

html5lib： git：git：//github.com/dart-lang/html5lib.git

现在我又来了

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

Answer 5

您是否使用代理访问互联网？ DartEditor无法设置代理，因此无法访问pub包。
