Question

您好我正在尝试学习并开始使用ExtJS（from here）。但似乎要么我错过了什么，要么在这里遇到一些问题。每当我尝试执行第一个基本的简单命令时：sencha generate app -ext Myapp ./app它的失败都有以下例外：

当我尝试执行sencha generate app MyApp ./app时会抛出异常：

Sencha Cmd v5.0.0.160 
[ERR] Unable to locate 'framework.dir' property from sencha.cfg and no framework directory specified
[ERR] Please ensure this command was executed from a valid framework directory
[ERR] No Framework specified

这里的framework.dir是什么？ 我已经下载了Sencha ExtJS v5.0.0 ，我需要将它保存在某个地方吗？

更新
运行sencha -sdk /path/to/extjs-5.0.0 generate app MyApp ./app给出相同结果后，说repo未正确初始化。

我已经安装了Ruby v1.9.3和Sencha Cmd v5.0.0.160，您可以在上面的异常之上看到它们。任何想法如何解决这个问题？

Answer 1

您必须从安装ext的目录运行Sencha Cmd，或者必须为其安装Ext的路径指定路径。

这应该有效：

sencha -sdk /path/to/ext/ generate app MyApp /where/you/want/the/app

Answer 2

为了避免任何混淆，只需通过＆＃34; sencha cmd＆＃34;，＆＃34; sencha sdk＆＃34;和您想要的应用程序目标目录。

/Users/vishnu/bin/Sencha/Cmd/5.1.0.26/sencha -sdk /Users/vishnu/Documents/senchaworkspace/ext-5.0.1 generate app TutorialApp /Users/vishnu/Documents/senchaworkspace/TutorialApp

这对我很有用

Sencha Cmd没有生成ExtJS应用程序
