typescript - tsserver : Error processing request (No Project)

Question

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.
...

我重新启动了带有详细日志记录的 visual-studio-code。

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

这提供了更多信息:

tsserver 认为我没有项目吗？

我在项目目录根目录下有一个“tsconfig.json”和“jsconfig.json”文件。我确实有一个运行 tsc 的“tasks.json”。我可以用具有类似结果的其他请求来刺激 tsserver。

根据 tsserver.js source code

$ 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>

问题是在“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目录太低。具体来说，找不到导致“无项目”错误的“tsconfig.json”文件。

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“files”或“include”选项与项目相关联。“tss.log”文件应包含有关打开的文件的“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。

这个问题没有出现在“tsc”中，因为它没有将“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
/<node-root>/lib/node_modules/typescript/lib/lib.es6.d.ts
/<my-project>/node_modules/@types/bluebird/index.d.ts
