問題描述
Ng add @nrwl/workspace throws Cannot read property 'paths' of undefined (Ng add @nrwl/workspace throws Cannot read property 'paths' of undefined)
我只是用 angular cli 創建一個項目，然後運行命令“ng add @nrwl/workspace”。將其更改為 nrwl 工作區。但是我收到以下錯誤“無法讀取未定義的屬性“路徑””。
我在互聯網上搜索了一下，發現有人有類似的錯誤，但他的錯誤是在 angular.json缺少測試我的 angular.json 中有所需的一切。
有人可以查看我的 json 文件並說出可能導致此錯誤的原因。我正在使用最新版本的 nrwl 和 angular

參考解法
方法 1:
I know it's late to answer this question but I hope this could be help.
I have experienced the same issue while trying to serve backend using both nestjs and express using Nx generate CLI (nx g @nrwl/express:app my‑app and nx g @nrwl/nest:app my‑nest‑app. Right after run nx server my‑app, terminal print below error
{
stack: "TypeError: Cannot read property 'endsWith' of undefined\n" +
' at createProjectRootMappings (/Users/path‑to‑root/node_modules/nx/src/project‑graph/file‑map‑utils.js:12:38)\n' +
' at createProjectFileMap (/Users/path‑to‑root/node_modules/nx/src/project‑graph/file‑map‑utils.js:27:33)\n' +
' at /Users/path‑to‑root/node_modules/nx/src/daemon/server/project‑graph‑incremental‑recomputation.js:92:85\n' +
' at Generator.next (<anonymous>)\n' +
' at fulfilled (/Users/path‑to‑root/node_modules/tslib/tslib.js:115:62)\n' +
' at processTicksAndRejections (internal/process/task_queues.js:95:5)',
message: "Cannot read property 'endsWith' of undefined\n" +
'\n' +
'Because of the error the Nx daemon process has exited. The next Nx command is going to restart the daemon process.\n' +
'If the error persists, please run "nx reset".'
}
Turn out there's missing line in file project.json generate by nx
{
"root": "packages/my‑app", // add this line
"sourceRoot": "packages/my‑app/src",
"projectType": "application",
"targets": {
....
},
....
}
方法 2:
I also encountered this kind of problem, I solved it like this: in the root directory tsconfig.json A paths parameter is required in. like this:
{
"compilerOptions": {
"paths": {
}
}
}
