重现步骤
我有一个私人项目，所以我无法分享回购，所以提前抱歉。我有一个 Angular 项目，我添加了原理图支持，因此我可以使用ng update. 所以我有一个带有migration.json文件的原理图文件夹：
{
"$schema": "../../../node_modules/@angular-devkit/schematics/collection-schema.json",
"schematics": {
"migration01": {
"version": "1.0.0-nav-menu-with-migration.3",
"description": "Update",
"factory": "./src/ng-update/index"
}
}
}
tsconfig.schematics.json：
{
"compilerOptions": {
"target": "es2015",
"module": "commonjs",
"moduleResolution": "node",
"declaration": true,
"sourceMap": true,
"lib": [
"dom",
"es2017",
"esnext.asynciterable"
]
},
"exclude": [
"**/files/*.ts",
"**/*.spec.ts"
]
}
tsconfig.schematics.spec.json：
{
"compilerOptions": {
"module": "commonjs",
"target": "es2015",
"moduleResolution": "node",
"types": [
"jasmine",
"node"
],
"lib": [
"es2017",
"dom"
],
"declaration": false
},
"include": [
"./spec/**/*.spec.ts"
]
}
jasmine.json：
{
"spec_dir": "projects/nav-menu/schematics/spec",
"spec_files": [
"**/*.spec.js"
],
"helpers": [
"projects/nav-menu/schematics/spec/helpers/**/*.js"
],
"stopSpecOnExpectationFailure": false,
"random": false
}
我有一个ng-update文件夹index.ts：
import { Rule, SchematicContext, SchematicsException, Tree } from "@angular-devkit/schematics";
export default function(): Rule {
return (tree: Tree, context: SchematicContext) => {
context.logger.warn("it's happening!");
const pkgPath = "/package.json";
const buffer = tree.read(pkgPath);
if (buffer == null) {
throw new SchematicsException("Could not read package.json");
}
const content = buffer.toString();
const pkg = JSON.parse(content);
if (pkg === null || typeof pkg !== "object" || Array.isArray(pkg)) {
throw new SchematicsException("Error reading package.json");
}
if (!pkg.dependencies) {
pkg.dependencies = {};
}
if (pkg.dependencies["@solarwinds/nav-menu-with-migration"]) {
pkg.dependencies["ngx-perfect-scrollbar"] = `^7.0.0`;
pkg.dependencies["ngx-device-detector"] = null;
tree.overwrite(pkgPath, JSON.stringify(pkg, null, 2));
}
return tree;
};
}
package.json对于我的导航菜单项目：
{
"name": "@solarwinds/nav-menu-with-migration",
"version": "0.0.1",
"peerDependencies": {
"css-element-queries": "~0.4.0",
"ngx-perfect-scrollbar": "^7.0.0",
"web-animations-js": "^2.3.1",
"@angular/cdk": "^6.0.2",
"@angular/common": "^6.0.7",
"@angular/core": "^6.0.7",
"@angular/router": "^6.0.7",
"@solarwinds/nova-xui": "6.3.0-alpha.10.1322",
"rxjs": "^6.0.0",
"zone.js": "^0.8.26"
},
"schematics": "./schematics/collection.json",
"ng-update": {
"migrations": "./schematics/migration.json"
}
}
发布包后，我会尝试nav-menu在使用此包的其他应用程序之一中进行更新。我尝试了许多不同的命令，但似乎没有一个可以migration.json在ng update. 所以我试过：
ng update @solarwinds/nav-menu-with-migration --to=1.0.0-nav-menu-with-migration.3 --migrate-only
我收到以下错误：Incompatible peer dependencies found. See above
Package "@solarwinds/nova-xui" has an incompatible peer dependency to "@angular/cdk" (requires "6.3.3", would install "6.4.7").
Package "@angular/http" has an incompatible peer dependency to "@angular/core" (requires "6.1.0" (extended), wouldinstall "6.1.10").

Package "@solarwinds/nova-xui" has an incompatible peer dependency to "rxjs" (requires "6.2.2", would install "6.3.3").
Incompatible peer dependencies found. See above.
所以我尝试使用--force标志，我确实package.json更新了我的文件，但我从来没有看到我的migration.json原理图运行。
g update @solarwinds/nav-menu-with-migration --to=1.0.0-nav-menu-with-migration.3 --force --migrate-only

我不确定为什么我的ng update命令没有运行。我想测试我的migration.json原理图，所以我指出我collection.json的指向，ng-update/index这样当我运行时，ng add @solarwinds/nav-menu-with-migration@1.0.0-nav-menu-with-migration.3我可以查看我的ng-update代码是否工作并且它是否按预期工作（注意：这只是为了测试目的，我不打算用来ng add运行迁移）。这是输出：
