Android NativeScript Path必须是字符串。收到undefined

Question

我是NativeScript的新手，我正在尝试导入/打开Visual Studio代码上的现有NatriveScript项目，我已经安装了Node，NativeScript 3.0.3，当我尝试构建或运行项目时我得到了这个调试控制台

[NativeScriptCli] execute: tns --analyticsClient VSCode --version
[NSDebugAdapter] Using tns CLI v3.0.3 on path 'tns'
[NSDebugAdapter] Running tns command...
[NativeScriptCli] execute: tns --analyticsClient VSCode debug android --no-client --watch

[31;1mPath must be a string. Received undefined
[NSDebugAdapter] The tns command finished its execution with code 127.
Error: Unknown signal: SIGQUIT
