我收到此错误:
sencha generate app GS ../GS
/Applications/SenchaSDKTools-2.0.0-beta3/sencha: line 2: which: command not found
/Applications/SenchaSDKTools-2.0.0-beta3/sencha: line 2: dirname: command not found
/Applications/SenchaSDKTools-2.0.0-beta3/sencha: line 3: /bin/node: No such file or directory
如果我只执行 sencha,我也会遇到同样的错误。请帮忙吗?
