Question

我在ubuntu 18.04终端中的angular中创建了新项目，但是出现了一些错误。我已经尝试通过这种方式进行安装：

npm install --save-dev @angular-devkit/build-angular

并通过更新ng和npm却没有使用，错误仍然相同

这是错误：

Could not find the implementation for builder @angular-devkit/build-angular:dev-server

通常会发生这种情况，因为您已将node.js版本..保留下来，但仍保留了npm缓存（在先前的node.js版本上使用电缆）

尝试：

1- UNINSTALL NODE.JS

2-{{1}}

3-Find the folder npm-cache and npm and DELETE IT（全局）

4-REINSTALL NODE.JS

5-重新运行GO IN PROJECT FOLDEER AND DELETE (rimraf ) NODE_MODULES

希望对您有帮助！

如何解决这个问题（/ home / user / MagnaFurn / node_modules / @ angular / cli / node_modules / @ angular-devkit / architect /）？
