是否可以在angular cli的工作区之外有一个库？
传统方案：
my-workspace/
... (workspace-wide config files)
projects/ (generated applications and libraries)
my-first-app/ --(an explicitly generated application)
... --(application-specific config)
e2e/ ----(corresponding e2e tests)
src/ ----(e2e tests source)
... ----(e2e-specific config)
src/ --(source and support files for application)
my-lib/ --(a generated library)
... --(library-specific config)
src/ --source and support files for library)
现在，我有一个库：my-lib2，它位于另一个目录中，而不是项目目录中。我把my-lib2的配置放在我工作区的angular.json文件中，带有相对路径，但是，当我编译这个文件时：ng-build-my-lib2，在工作区内，我有以下错误：

工作区内部angular.json的配置：
...
...
"my-lib2": {
"projectType": "library",
"root": "projects/../../my-lib2/",
"sourceRoot": "projects/../../my-lib2/src",
"prefix": "lib",
"architect": {
"build": {
"builder": "@angular-devkit/build-ng-packagr:build",
"options": {
"tsConfig": "projects/../../my-lib2/tsconfig.lib.json",
"project": "projects/../../my-lib2/ng-package.json"
},
"configurations": {
"production": {
"tsConfig": "projects/../../my-lib2/tsconfig.lib.prod.json"
}
}
},
"test": {
"builder": "@angular-devkit/build-angular:karma",
"options": {
"main": "projects/../../my-lib2/src/test.ts",
"tsConfig": "projects/../../my-lib2/tsconfig.spec.json",
"karmaConfig": "projects/../../my-lib2/karma.conf.js"
}
},
"lint": {
"builder": "@angular-devkit/build-angular:tslint",
"options": {
"tsConfig": [
"projects/../../my-lib2/tsconfig.lib.json",
"projects/../../my-lib2/tsconfig.spec.json"
],
"exclude": [
"**/node_modules/**"
]
}
}
}
}},
...
...
tsconfig.lib.ts(my-lib2的配置文件(
{
"extends": "../my-workspace/tsconfig.json",
"compilerOptions": {
"outDir": "../my-workspace/out-tsc/lib",
"target": "es2015",
"declaration": true,
"inlineSources": true,
"types": [],
"lib": [
"dom",
"es2018"
]
},
"angularCompilerOptions": {
"skipTemplateCodegen": true,
"strictMetadataEmit": true,
"enableResourceInlining": true
},
"exclude": [
"src/test.ts",
"**/*.spec.ts"
]
}
可以看出，所有路径都是相对的。。。
知道如何在工作区的angular.json中配置条目以将库从项目路径中移除吗？
解决方案是正确配置库的tsconfig.lib.ts文件。
目录架构：
my-lib2/
...
src/
my-workspace/
...
projects/
my-first-app/
...
e2e/
src/
...
src/
my-lib/
...
src/
工作区angular.json文件中的my-lib2条目：
"my-lib2": {
"projectType": "library",
"root": "../my-lib2",
"sourceRoot": "../my-lib2/src",
"prefix": "lib",
"architect": {
"build": {
"builder": "@angular-devkit/build-ng-packagr:build",
"options": {
"tsConfig": "../my-lib2/tsconfig.lib.json",
"project": "../my-lib2/ng-package.json"
},
"configurations": {
"production": {
"tsConfig": "../my-lib2/tsconfig.lib.prod.json"
}
}
},
"test": {
"builder": "@angular-devkit/build-angular:karma",
"options": {
"main": "../my-lib2/src/test.ts",
"tsConfig": "../my-lib2/tsconfig.spec.json",
"karmaConfig": "../my-lib2/karma.conf.js"
}
},
"lint": {
"builder": "@angular-devkit/build-angular:tslint",
"options": {
"tsConfig": [
"../my-lib2/tsconfig.lib.json",
"../my-lib2/tsconfig.spec.json"
],
"exclude": [
"**/node_modules/**"
]
}
}
}
}},
tsconfig.lib.tsmy-lib2目录中的文件配置：
{
"extends": "../my-workspace/tsconfig.json",
"compilerOptions": {
"outDir": "../my-workspace/out-tsc/lib",
"target": "es2015",
"declaration": true,
"inlineSources": true,
"types": [],
"lib": [
"dom",
"es2018"
],
"baseUrl": "../my-workspace/",
"paths": {
"*": ["../my-workspace/node_modules/*"]
}
},
"angularCompilerOptions": {
"skipTemplateCodegen": true,
"strictMetadataEmit": true,
"enableResourceInlining": true
},
"exclude": [
"src/test.ts",
"**/*.spec.ts"
]
}
这是配置中的重要部分：
...
"baseUrl": "../my-workspace/",
"paths": {
"*": ["../my-workspace/node_modules/*"]
}
...
