使用 powershell 将路径永久添加到 Windows 似乎不起作用 [英] Adding path permanently to windows using powershell doesn't appear to work

问题描述

我遵循 这个程序 以使用 powershell 永久添加 SumatraPDF 的路径.链接中的最后几个命令用于检查是否确实添加了路径.

I followed this procedure in order to permanently add a path to SumatraPDF using powershell. The last few commands from the link are meant to check that the path has indeed been added.

当我使用以下命令访问路径时，

When I access the path using the following command,

(get-itemproperty -path 'Registry::HKEY_LOCAL_MACHINESystemCurrentControlSetControlSession ManagerEnvironment' -Name PATH).Path.split(';')

结果包括 SumatraPDF 的路径

the result includes the path to SumatraPDF

C:Windowssystem32
C:Windows
C:WindowsSystem32Wbem
C:WindowsSystem32WindowsPowerShellv1.0
C:WindowsSystem32OpenSSH
C:ProgramDatachocolateyin
C:	exlive2021inwin32
C:Users921479AppDataLocalSumatraPDF

但是，当我使用以下命令访问它时，

However when I access it using the following command,

($env:path).split(';')

结果不包含 SumatraPDF 的路径:

the result does not contain the path to SumatraPDF:

C:Windowssystem32
C:Windows
C:WindowsSystem32Wbem
C:WindowsSystem32WindowsPowerShellv1.0
C:WindowsSystem32OpenSSH
C:ProgramDatachocolateyin
C:	exlive2021inwin32
C:Users921479AppDataLocalMicrosoftWindowsApps

最后，实际上传递 sumatrapdf 不起作用，这表明真正的路径是使用 get-itemproperty 命令访问的路径.

Finally, actually passing sumatrapdf does not works, which indicates to me that the real path is the one accessed using the get-itemproperty command.

为什么注册表中设置的路径与$env:path中设置的路径不对应?链接 我关注了?我该如何纠正?

Why does the path set in the registry not correspond to the one set in $env:path? Is there a mistake in the procedure shown in the link I followed? How can I correct it?

我应该提一下，我已经尝试过重新启动 shell，但它没有帮助.

I should mention I have already tried restarting the shell but it doesn't help.

推荐答案

使用 setx 永久更新环境变量.不要破解注册表.

Use setx to permanently update an environment variable. Don't hack the registry.

调用 setx 后，只需在当前会话中手动更新 Path 环境即可.Powershell:在 PowerShell 中重新加载路径

After you invoke setx, just update the Path environment manually in the current session. Powershell: Reload the path in PowerShell
