semver从哪里来？

Question

我之前做过如下：

MacBook-Pro:bb-ns-ng-dr ishandutta2007$ npm uninstall -g semver 
MacBook-Pro:bb-ns-ng-dr ishandutta2007$ npm uninstall semver 
MacBook-Pro:bb-ns-ng-dr ishandutta2007$ rm -rf platforms/ 
MacBook-Pro:bb-ns-ng-dr ishandutta2007$ rm -rf node_modules/ 
MacBook-Pro:bb-ns-ng-dr ishandutta2007$ tns build android --clean 

我不断收到semver重复资源错误，即使semver既不是任何的节点模块I定义，也没有任何theri三级依赖。抛开重复资源的共鸣，我更加好奇它是如何摆在首位的。

Could not merge source set folders: [app/node_modules/semver/semver.min.js] /Users/ishandutta2007/Documents/Projects/bb-ns-ng-dr/platforms/android/src/main/assets/app/node_modules/semver/semver.min.js [app/node_modules/semver/semver.min.js] /Users/ishandutta2007/Documents/Projects/bb-ns-ng-dr/platforms/android/src/main/assets/app/node_modules/semver/semver.min.js.gz: Error: Duplicate resources [app/node_modules/semver/semver.browser.js] /Users/ishandutta2007/Documents/Projects/bb-ns-ng-dr/platforms/android/src/main/assets/app/node_modules/semver/semver.browser.js [app/node_modules/semver/semver.browser.js] /Users/ishandutta2007/Documents/Projects/bb-ns-ng-dr/platforms/android/src/main/assets/app/node_modules/semver/semver.browser.js.gz: Error: Duplicate resources

这里是我的节点模块包树的样子

Answer 1

npm取决于semver，所以它似乎不太可能，你完全可以得到从全局摆脱它。 According to npm有超过4,000个包依赖于它。

不要问它是从哪里来的，也许你会想把重点放在你遇到的问题上。
