The 'invalid command name' message comes because the program command being executed is not a Tcl command. Tcl scripts use "exec" to invoke other programs. When attempting to execute an application, exec first searches for the name as it was specified.
出现这个问题主要是未成功加载tcl的解析库，去tcl/tk的安装目录找到lib子目录，拷贝到运行程序的上一级目录即可
