Question

我执行了ExtJS 5升级指南中指定的以下内容：

sencha app upgrade -ext

我得到了这个输出错误：

sencha app upgrade -ext

当我执行简单的＆＃34; sencha app upgrade＆＃34;我明白了：

Sencha Cmd v5.0.0.160

Answer 1

尝试将app.cmd.version = 3.0.0.250（或正在运行的任何版本的cmd）添加到应用的sencha.cfg文件中。这对我有用。

Answer 2

虽然我不知道为什么，但我也将上述错误从Ext 5 Beta升级到GA，唯一的方法是重新生成应用程序（sencha generate app ...）并手动将文件复制到新的生成文件夹结构。

Answer 3

在Linux上它默认在/root/.bashrc中定义它（不知道为什么它说3_0_0）：

export PATH=/root/bin/Sencha/Cmd/5.0.0.160:$PATH
export SENCHA_CMD_3_0_0="/root/bin/Sencha/Cmd/5.0.0.160"

Windows上的

...转到＆＃34;系统设置＆＃34; - ＆GT; ＆＃34;高级＆＃34; - ＆GT; ＆＃34;环境变量......＆＃34;

并在那里定义（然后可以简单地键入＆＃34; sencha＆＃34;并且它将被知道）。

如果安装程序没有正常运行（Linux示例）：

cd /tmp/sencha1403206728375
./SenchaCmd-5.0.0.160-linux-x64.run
cd .. && rm -R ./sencha1403206728375/

我相信安装程序更喜欢从当前目录调用 - 至少在sencha upgrade被卡住时这会有所帮助。

一旦环境更新，需要重新连接（重启？），以扩展PATH规范。使用更新的SenchCmd然后可以使用更新的SDK（似乎向下兼容）。

从ExtJS 4.2.1升级到ExtJS 5时，为什么会出现错误？
