ERROR: Build failed: exit code 1

有人知道这是从哪里来的吗？ 看起来扫描仪正试图访问XXX/bootwatch-paper.css 第一行的第 79 个字符，它只有 78 个字符。为什么它会尝试读取第 79 个字符？ 这可能是编码问题吗？ 如何解决这个问题？

干杯！

Answer 1

我的一个 AssemblyInfo.cs 文件也有类似的问题。这绝对是编码。我在 Sublime Text 中打开文件并用不同的编码保存它，看看有什么用。以下是我发现的，虽然对你来说可能会有所不同，因为我使用的是 C# 插件，而你使用的是 css 插件。

1. UTF-8 - 成功
2. 带有 BOM 的 UTF-8 - 成功
3. UTF-16 LE - 成功
4. 带有 BOM 的 UTF-16 LE - 失败
5. UTF-16 BE - 成功
6. UTF-16 BE 与 BOM - 失败
7. 西方 (Windows 1252) - 成功

Answer 2

可能是文件编码是：带有BOM的UTF-8编码， 您应该将文件更改为不带 BOM 的 UTF-8 编码
