我遇到了一个非常奇怪的问题，但无法解决。甚至 Google 团队也在努力解决这个问题，但到目前为止无法解决。

我有一个 CSS 文件，它很长一段时间以来都是一样的，并且在过去 1-2 年里从未改变过。现在我想改变一个地方。我将 max-width 更改为 max-height 并保存。现在我正在部署代码，但它抛出了一个异常:

我再次将高度更改为宽度，它可以正确部署。在这两种情况下，文件编码类型都是 UTF-8。对此有任何猜测或解决方案吗？如果您需要任何进一步的信息，我很乐意与您分享。

解决方案

大多数时候，即使您将文件编码类型更改为 UTF-8，它也无法识别。最好的方法是强制要求 appcfg.py 以 UTF-8 编码格式处理您的文件。您可以通过更改 app.yaml 中文件格式的 mime_type 来实现，如下所示:

- url: /(.*\.(css$))
  static_files: \1
  upload: (.*\.(css$))
  mime_type: text/css; charset=UTF-8

通过这种方式，您的文件将被视为 UTF-8，并且您的部署不会失败。

最佳答案

打开yourfile.css，并确保它以utf-8 编码保存。根据您的文本编辑器，您可以转到另存为，然后选择编码。错误告诉你这是 ascii 编码的，它在位置 1934 处发现了一个非 ascii 字符。使用你的文本编辑器找到第 1934 个字符，你就会看到这个问题。您是否从网上复制/粘贴了该行？如果是这样，您很可能有一个非 ASCII 连字符、冒号、分号或引号。
