使用ng update命令更新Angular

使用 ng update 命令查看更新:

$ ng update
We analyzed your package.json, there are some packages to update:
  Name             Version          Command to update
 -----------------------------------------------------------
  @angular/cli     7.1.1 -> 7.1.2   ng update @angular/cli
  @angular/core    7.1.1 -> 7.1.2   ng update @angular/core

There might be additional packages that are outdated.
Run "ng update --all" to try to update all at the same time.

使用 ng update 更新 @angular/cli 包:

$ ng update @angular/cli
    Updating package.json with dependency @angular/cli @ "7.1.2" (was "7.1.1")...
UPDATE package.json (1528 bytes)
updated 10 packages in 18.119s

再次查看:

$ ng update

 --------------------------------------------------------------
  @angular/core    7.1.1 -> 7.1.2     ng update @angular/core
