Tcl 包要求HTTP不工作

我在使用“包需要http”时遇到问题。如果我只有一个带有该行的tcl文件，则会出现以下错误：

can't set "formMap": variable is array
while executing
"variable formMap [array get map]"

                set ..."

有人能帮我解决这个问题吗？多谢各位

编辑-->包括以下内容：

catch {namespace delete ::http}

我遵循了以下程序包要求http：

http::geturl "https://google.com"   

但是，我现在得到以下错误：

can't set "formMap": variable is array
while executing
"variable formMap [array get map]"

看起来您/NaviServer正在解释器中以某种方式重新加载http包，该解释器已经加载了不同版本的http包。真奇怪

更奇怪的是，http库最年轻的版本可以追溯到2004年；它在http 2.5.0中进行了更改，并在2005年初升级到该版本。（显然是我做的，但我真的不记得了。）更改应用于Tcl 8.4和8.5版本（以及8.6和更高版本），因此我非常确定您使用的古老版本确实不值得使用。这是那些足够老的版本的上限，足以触发你所看到的行为；他们可能比这更老

总而言之，这确实很奇怪。您实际上不应该将包的不同版本加载到单个Tcl解释器中。这并不是一个特别受支持的使用模式（主要是因为大多数软件包无法很好地卸载它们的状态，因为很难很好地完成）

解决方法是在

程序包需要之前执行此操作：

catch {namespace delete ::http}

你好，多纳尔，谢谢你的回复。我已经在代码中包含了更改，但仍然有错误。我已经在帖子的顶部包含了错误消息。非常感谢。
