无法运行Windows docker容器中Path中的可执行文件

Question

我正在尝试从Power Shell的容器内部运行可执行文件，并收到一条找不到该错误消息的错误消息。但是，我已经确认它的目录在Path中，并且可执行文件在我期望的位置。我想念什么？

PS C:\docker_work> IarBuild.exe
IarBuild.exe : The term 'IarBuild.exe' is not recognized as the name of a cmdlet, function, script file, or operable

PS C:\docker_work>

我的docker文件包含以下内容：

...
# Add the IAR common\bin\ folder to the image's PATH
RUN setx path \
  "%path%;C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.1\common\bin\"
...
CMD [ "powershell.exe", "-executionpolicy" , "Unrestricted" ]

[您将需要添加。\，因此它看起来像。\ IarBuild.exe，因为它当前正在尝试将.exe作为cmdlet处理
