Error message installing Chocolatey in PowerShell

Question

I'm trying to install Chocolatey to use with PowerShell.

The recommended way to install it is copy and paste the following line.

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('http://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin

But I get the following error:

At line:1 char:13
+ @powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object  ...
+             ~~~~~~~~~~
Unexpected token '-NoProfile' in expression or statement.

+ @powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object  ...

+ ... nstall.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin
+                    ~~
The token '&&' is not a valid statement separator in this version.

The splatting operator '@' cannot be used to reference variables in an expression. '@powershell' can be used only as
an argument to a command. To reference variables in an expression use '$powershell'.
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException

ExecutionPolicy is set as RemoteSigned and I'm running Powershell v3

I tried some apply some bits of the installation code rather than the whole line, but basically, anything after @Powershell is an unexpected token.

It's a batch script. Try running the script in a CMD window, not in a powershell console. – Bejewel

In my box the line return error at @powershell for the incorrect use of splatting operator @ – Duodenal

Answer 1

You must start that line from cmd.exe (a "standard" command prompt), not from PowerShell.

Cornu

You're absolutely right. I also had to add powershell.exe folder to the PATH variable: C:\Windows\SysWOW64\WindowsPowerShell\v1.0; – Disorientate

Yep, take a look at this for the powershell command: github.com/chocolatey/chocolatey/wiki/Installation – Nedanedda

Answer 2

In PowerShell v3+ the easiest way is:

1. Open a PowerShell window (run as administrator)

2. Check the version of PowerShell is greater than 3:

    $PSVersionTable.PSVersion
   

3. Enable execution of PowerShell scripts?

   set-executionpolicy remotesigned
   

4. In PowerShell

   iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex

Answer 3

I was unable to install Chocolatey on my Windows 10 64-bit OS installation. I was getting powershell not recognized as internal or external command. Finally I found the solution, so to people who ever facing the exact same problem as I did, here is the solution for you.

The reason why you get such an error is because the WindowsPowerShell path is not set. So kindly set the Path as

%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

Go to Environment variable (see below). You see that Path variable, click on Edit and you see one more pop-up window, which shows a couple of paths there. Now click on New and copy-paste the above path. Close your CommandPrompt(admin) and open it again. Run the command given by Chocolatey, and now it starts downloading.

Here is a step-by-step guide:

Go to Control Panel → System → Advanced System Settings → Environment Variables → User variable for Users → Select Path Variable → click Edit → Click on New → paste this %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\ → Click OK → you're done.
