PyPy 7.3.16（通过Scoop全局安装）
RamDisk内存盘（通过ImDisk ToolKit挂载）

复现过程

设置 TEMP环境变量到 R:\Temp
运行命令：

pypy -m ensurepip

成功地报错了，报错信息：

样例分析

异常调用栈中，R:是笔者使用 ImDisk挂载的Ramdisk盘符，R:\Temp是笔者通过 ImDisk自带工具自动设置的 %TEMP%环境变量所指路径。

根据调用栈集中在 R:\Temp来看，笔者初步认为 ensurepip无法运行是因为 %TEMP%环境变量因为某种缘故无法访问的关系（由于笔者的 nushell至今无法访问到 R:盘符下的路径，所以哥们很自然地就认为是 %TEMP%环境变量相关），那么更改 %TEMP%环境变量似乎就可以解决了，至于具体的原因和影响需要后续分析。

解决方案

修改 `%TEMP%`环境变量

只需要在终端里面临时指定 TEMP环境变量到 R:\以外的路径即可，如在 PowerShell下运行：

$env:TEMP = "$env:LOCALAPPDATA/Temp"; pypy -m ensurepip

则可以正常得到预期输出：

Looking in links: c:\Users\username\.cache\tmpj0axfryo
Requirement already satisfied: setuptools in c:\programdata\scoop\apps\pypy3\7.3.16\lib\site-packages (65.5.0)
Requirement already satisfied: pip in c:\programdata\scoop\apps\pypy3\7.3.16\lib\site-packages (23.0.1)

不过，TEMP环境变量使用 ~指代家目录的话，ensurepip似乎也是无法解析的，Windows下改成其它的路径或者用 USERPROFILE变量就好。
