在角度2应用程序中运行时出现错误

标签： angularjs angular angular-cli

我首先使用npm install -g angular-cli命令安装了angular-cli并创建了一个angular-cli项目。然后我使用ng new Angular2TestProject命令创建了项目，并将目录更改为Angular@TestProject并运行ng serve命令。这是错误的。之后，我运行npm install和npm upgrade，然后再运行ng serve，但在命令提示符中仍然存在相同的错误。错误如下：

webpack: bundle is now VALID.

错误日志清楚地显示了Module not found的问题，您仅在一个位置将项目名称从Angular2TestProject更改为Angular @ TestProject，您需要在项目名称所在的位置更改其名称（路径在错误日志中给出）。尝试更改名称并运行。
