Dart 一直工作到我更新了编辑器，现在我得到了现有和新项目的错误。我尝试完全重新安装 Dart。当我在 web-ui 上为新项目运行 pub install 时收到以下消息：

--- Jun 11, 2013 10:25:11 PM Running pub install ... ---
Pub install failed, [255] Unhandled exception:
FileIOException: Cannot open file 'C:\Users\Phloxicon\Documents\dart\dart-sdk\bin\version' (OS Error: The system cannot find the file specified.

#7      main (file:///e:/b/build/slave/dart-editor-win-trunk/build/dart/sdk/lib/_internal/pub/bin/pub.dart:61:30)

正确安装时该目录中没有“版本”文件。我添加了该文件并收到以下消息：

--- Jun 11, 2013 10:23:42 PM Running pub install ... ---

Pub install failed, [69] Resolving dependencies...

Failed NSS_Init call.

当我创建一个新项目时，我得到以下信息：

有任何想法吗？

Cannot open file 'C:\Users\Phloxicon\Documents\dart\dart-sdk\bin\version'

这看起来你的 Dart 安装坏了。当您安装 Dart SDK 时，该文件绝对应该存在，而 pub 没有它就无法工作。

您是自己构建 SDK，还是只是下载预构建的 SDK？

尽量pub update不要pub install更新缓存的包。

然后Reanalyze Sources从同一个工具菜单中使用。请务必在运行之前清除所有日志，Reanalyze Sources以便确保它进行了干净的构建。

如果这不能让您完全清理干净，请删除packages您在项目树中看到的所有out目录，以及可能存在的所有目录以及pubspec.lock文件。然后运行pub install。

这通常让我回到干净的构建。
