问题：

npm测试找不到socket.io.js文件

常小白
2023-03-14

我正在尝试使用Karma进行测试，我正在遵循Angulars自己的测试指南。目前我正在使用最基本的测试类，但在运行它时遇到了问题。

测试类别：

describe('1st test',()=>{
it('true is true', ()=> expect(true).toBe(true)); });

当我使用npm test运行它时，在命令提示符中出现以下错误：

我已经检查了它找不到的文件，它存在于错误所述的目录中，所以我不知道该怎么办。

这些是XHR请求的404错误。这并不意味着文件系统中不存在该文件，而是通过访问该特定路径不提供该文件。您的服务器不太可能为整个文件系统提供服务，因此您不应该担心该文件是否存在，而是担心它是否是从您的程序试图访问它的特定URL提供的。

有关示例，请参阅此答案中的代码示例：

  • 使用Express获取数据/将数据写入localhost

这里socket.io.js文件在超文本标记语言中引用为：

<script src="/socket.io/socket.io.js"></script>

不是文件系统中的绝对路径，也不是包含node_modules的路径。HTTP 请求中的路径和文件系统中的路径是不同的，404 错误是特定于 HTTP 的。
