tsserver:错误处理请求(无项目)

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.
...

我用详细日志重新启动了visual-studio-code.

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

这提供了更多信息:

tsserver是否认为我没有项目？

我在项目目录root中有'tsconfig.json'和'jsconfig.json'文件.我有一个运行tsc的'tasks.json'.我可以用其他类似结果的请求激发tsserver.

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'树顶部附近有一个空的'jsconfig.json'文件('src/ts/jsconfig.json').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'No Project'错误.

executeCommand()函数返回undefined,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文件的'Info'消息.确保打开您关注的所有文件,特别是检查"配置文件名"的位置,以确保获得正确的文件.

这个问题没有出现'tsc',因为它没有将'jsconfig.json'视为项目的指标.

典型的日志文件看起来应该更像这样:

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
