您好，我在下面的bower.json中使用它来构建我的应用程序，我们在其中提供url时使用了pd-helpers依赖，如果我更改了其中的pd-helper或个人访问令牌的某些版本号，则在运行bower时必须成功安装其运行bower.json并再次运行bower install，然后说出bower ENOTFOUND包pd-helpers：未找到
我观察到一件事，如果我在更改后和运行Bower安装之前手动删除bower_component文件夹，那么我能够成功构建而不会出现上述问题。
无论我要更改的是Bower.json中pd-helpers的版本（在github中都可用），因此也没有机会认为那里没有该软件包的版本。
