Jython无法安装“ensurepip”

Question

我正在尝试将软件包安装到Jython安装中，但到目前为止我没有成功。你知道吗

Jython的安装在我的机器上的这个位置。[注意路径已被手动截断-'..']

"F:\Programs\..\docs\javacommon\jython.jar"

在同一位置有一个现有的空库位置：

"F:\Programs\..\docs\javacommon\Lib"

当我尝试运行以下命令来安装EnsureIP时：

java -jar jython.jar -m ensurepip

但是，此操作失败，并出现以下错误：

最初看起来可疑的是安装路径及其包含的“.jar”路径：

"F:\Programs\..\javacommon\jython.jar\Lib\ntpath.py"

我看了一下搜索路径“看看上面是什么：

['', 'F:\\Programs\\..\\javacommon\\Lib', 'F:\\Programs\\..\\javacommon\\jython.jar\\Lib', '__classpath__', '__pyclasspath__/']

我已经删除了路径中的所有内容，禁止“F:\Programs\..\javacommon\Lib”再次测试安装，但在重新启动Jython之后系统路径自动重置为上述值。你知道吗

你知道我该怎么进步吗？目前，我正试图让它安装在正确的文件夹路径库，以便我可以继续。你知道吗

请注意，我的最终目标是为我的Jython安装安装以下内容：

python -m pip install numpy scipy matplotlib ipython jupyter pandas sympy nose

非常感谢
