node: win11安装chocolatey时报错的解决

一，报错信息：

 powershell -c "irm https://community.chocolatey.org/install.ps1|iex"
Forcing web requests to allow TLS v1.2 (Required for requests to Chocolatey.org)

    + FullyQualifiedErrorId : UnauthorizedAccess
Ensuring Chocolatey commands are on the path
Ensuring chocolatey.nupkg is in the lib folder

问题原因：

没有权限运行脚本，打开终端时要用管理员方式，如图：

启动后放开执行脚本的权限，命令：

 Set-ExecutionPolicy Bypass -Scope Process -Force

如图:

二，报错信息

  powershell -c "irm https://community.chocolatey.org/install.ps1|iex"
警告: Files from a previous installation of Chocolatey were found at 'C:\ProgramData\chocolatey'.
警告: An existing Chocolatey installation was detected. Installation will not continue. This script will not overwrite
existing installations.
If there is no Chocolatey installation at '', delete the folder and attempt the installation again.

Please use choco upgrade chocolatey to handle upgrades of Chocolatey itself.
If the existing installation is not functional or a prior installation did not complete, follow these steps:
 - Backup the files at the path listed above so you can restore your previous installation if needed.
 - Remove the existing installation manually.
 - Rerun this installation script.
 - Reinstall any packages previously installed, if needed (refer to the lib folder in the backup).

Once installation is completed, the backup folder is no longer needed and can be deleted.

问题原因：

发现chocolatey已安装了，目录在'C:\ProgramData\chocolatey'
原因是之前安装的部分的残留

解决:删除无用的安装目录：

 Remove-Item -Path "C:\ProgramData\chocolatey" -Recurse -Force

 

三，报错信息：

安装过程未报错，但安装完后choco命令执行报错：

 choco --version

确，然后再试一次。

原因：安装完成后，当前窗口的环境变量未得到刷新
解决：关掉当前终端，重新打开一次即可
