问题描述
我正在尝试将angular更新到最新版本.
I'm trying to update angular to latest version .
我已经更新了全局@ angular/cli
I have updated global @angular/cli
npm install -g @angular/cli
然后，当我尝试使用ng update @angular/cli更新本地@ angular/cli时，出现此错误:
Then when I try to update local @angular/cli using ng update @angular/cli I get this error:
Error: Unexpected end of JSON input
Unexpected end of JSON input
这是我的package.json
Here's my package.json
{
"name": "apimap",
"version": "0.0.0",
"license": "MIT",
"scripts": {
"ng": "ng",
"start": "ng serve",

}
格式正确.
当ng服务时，该项目正在编译并且可以正常工作.
the project is compiling and working when ng serve.
我正在使用Node的v9.9.0和npm的6.0.1.
I'm using v9.9.0 of Node and 6.0.1 of npm.

推荐答案
只需确保运行以下步骤:
Just to be sure run the following steps:
npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@latest
然后在您的本地项目包中:
Then in your Local project package:
rm -rf node_modules dist
npm install --save-dev @angular/cli@latest
npm i
ng update @angular/cli
ng update @angular/core
如果这不起作用，我认为您应该手动更新package.json
If this doesn't work, I think you should update manually the package.json
"dependencies": {
"@angular/animations": "^6.0.3",
"@angular/common": "^6.0.3",
"@angular/compiler": "^6.0.3",
"@angular/core": "^6.0.3",
"@angular/forms": "^6.0.3",
"@angular/http": "^6.0.3",
"@angular/platform-browser": "^6.0.3",
"@angular/platform-browser-dynamic": "^6.0.3",
"@angular/router": "^6.0.3",
"core-js": "^2.5.4",
"rxjs": "^6.0.0",
"zone.js": "^0.8.26"
},
"devDependencies": {
"@angular/compiler-cli": "^6.0.3",
"@angular-devkit/build-angular": "~0.6.5",
"typescript": "~2.7.2",
"@angular/cli": "~6.0.5",
"@angular/language-service": "^6.0.3",
"@types/jasmine": "~2.8.6",
"@types/jasminewd2": "~2.0.3",
"@types/node": "~8.9.4",
"codelyzer": "~4.2.1",
"jasmine-core": "~2.99.1",
"jasmine-spec-reporter": "~4.2.1",
"karma": "~1.7.1",
"karma-chrome-launcher": "~2.2.0",
"karma-coverage-istanbul-reporter": "~1.4.2",
"karma-jasmine": "~1.1.1",
"karma-jasmine-html-reporter": "^0.2.2",
"protractor": "~5.3.0",
"ts-node": "~5.0.1",
"tslint": "~5.9.1"
}
如果手动更新，则删除.angular-cli.json并创建angular.json
To remove .angular-cli.json and create angular.json if updated manually
ng update @angular/cli --migrate-only --from=1.7.4
