在“Visual Studio Code”（v1.5.3）中处理 TypeScript（v2.0+）项目时，出现以下错误：

[Error - 10:03:50 AM] 'format' request failed with error.
Error processing request. No Project.
Error: No Project.
...

我使用详细日志记录重新启动了可视化工作室代码。

export TSS_LOG='-level verbose -file <my-home>/tss.log'

这提供了更多信息：

tsserver 相信我没有项目吗？

我在项目目录根目录中有一个“tsconfig.json”和“jsconfig.json”文件。我确实有一个运行 tsc 的“tasks.json”。我可以用其他请求来刺激 tsserver，得到类似的结果。

根据tsserver.js 源代码

$ export TSS_LOG='-level verbose -file <my-home>/tss.log'
$ code

详细日志文件包含答案，但未报告为错误。

Info 2    Config file name: /<my-project>/src/ts/jsconfig.json
Err 3     Exception on executing command {"seq":0,"type":"request","command":"open","arguments":{"file":"<my-project>/src/ts/<a-class-file>.ts","fileContent":"..."}}: Unexpected end of input
<stack-trace>

问题是“src”树（“src/ts/jsconfig.json”）顶部附近有一个空的“jsconfig.json”文件。这导致在文件层次结构中搜索项目根太低。具体来说，找不到“tsconfig.json”文件，导致“无项目”错误。

executeCommand() 函数返回未定义，当关联的处理程序找不到包含该文件的项目时会发生这种情况。这些文件通过“tsconfig.json”中的“文件”或“包含”选项与项目相关联。“tss.log”文件应包含有关已打开文件的“信息”消息。确保您关心的所有文件都已打开，特别是检查“配置文件名”的位置以确保您获得正确的文件。

'tsc' 并未出现此问题，因为它不将 'jsconfig.json' 视为项目的指标。

一个典型的日志文件应该看起来更像这样：

Info 0    request: {"seq":0,"type":"request","command":"open","arguments":{"file":"/<my-project>/src/ts/folder1/ClassA.ts","fileContent":"..."}}
Info 1    Search path: /<my-project>/src/ts/folder1
Info 2    Config file name: /<my-project>/tsconfig.json
Err 3     Add recursive watcher for: /<my-project>
Err 4     Add recursive watcher for: /<my-project>/src/ts
Info 5    Opened configuration file /<my-project>/tsconfig.json
Info 6    Project (configured) 0
