![]() Keep in mind that you will need to reinstall global packages and may need to re-install local packages when when you switch the version of Node you are using. Using a Node.js version manager such as nvm-windows can be very helpful if you are doing Node.js development and need to test against different versions. Note however, that many packages have uncertain management and that these packages may use different folder locations than those mentioned above. If you are already using Chocolatey, you may want to use this tool to install Node.js (e.g. There are two potentially useful alternatives to installing Node.js with the MSI installer.Ĭhocolatey is a package manager for Windows similar to APT or yum on Linux and brew on the Macintosh platforms. If for some reason, you need a different installation, you can use the Downloads Page. While you can use either 32 bit or 64 bit versions on 64 bit Windows, it is recommended to use the 64bit version of Node. Download the appropriate version from the official Node.js home page. Standard installations of Node.js on Windows require local administrator rights. the PowerShell Tutorial and PowerShell One-Liners sites may also be helpful. You will very likely need to be quite familiar with command prompts as you learn about Node-RED and Node.js and it will be worth while reading some of the Microsoft articles on PowerShell. "elevated") command prompt unless specifically instructed to. Note : You should not use an administrative (a.k.a. ![]() You should receive back output that looks similar to: Using Powershell: node -version npm -version Once installed, open a command prompt and run the following command to ensure Node.js and npm are installed correctly. After installation completes, close any open command prompts and re-open to ensure new environment variables Installing Node.js requires local administrator rights if you are not a localĪdministrator, you will be prompted for an administrator password on install. It will offer you the best version for your system. It is recommended to use PowerShell on all newer versions of Windows as this gives you access to commands and folder names that are closer to those of Linux/Mac.ĭownload the latest LTS version of Node.js from the official Node.js home page. Where this is used, it refers to either the Windows cmd or PowerShell terminal shells. Complete code example on GitHub (SasWorkspaceDownloadFile.Note : Some of the following instructions mention the "command prompt".NOTE: There were 428 observations read from the data set SASHELP.CARS.ĭownloaded c:\temp\hist.png: SIZE = 15092 bytes NOTE: Listing image output written to /projects/result/hist.png. NOTE: PROCEDURE SGPLOT used (Total process time): Here's an excerpt from the output when the script runs: Write-Output "Downloaded $localPath\$destImg.png: SIZE = $byteCount bytes" # if less than requested bytes, we're at EOF ![]() # read bytes from source file, 1K at a time $objStream = $objFile.OpenBinaryStream($StreamOpenModeForReading) # assign a Fileref so we can use FileService from IOM (The complete example is available on GitHub.) ![]() Here's a PowerShell program snippet that implements these steps. When completed, close the local and remote file handles, and unassign the SAS file reference ( Close method and DeassignFileref method).Write the contents into a local file (PowerShell objects).Read the contents of the file into a local array of bytes ( Read method, repeating in 1K increments).Tell SAS to open the remote file for reading ( OpenBinaryStream method).Obtain a SAS reference to the file (FileService AssignFileref method.For a file download operation, these are the basic steps: As with most file-based operations in SAS, the FileService relies on the use of a SAS fileref, or the name that SAS uses to reference your file within a program. The SAS Workspace provides the FileService API, which allows you to transfer file-based content between your local application and the SAS session. When the program runs, it creates a file named hist.png in the /projects/results folder within the SAS session. ![]() Ods listing gpath='$destPath' style=plateau # change these to your own SAS-session-based Consider this program, implemented in a PowerShell script, which creates an image with PROC SGPLOT: What if your program creates Output Delivery System (ODS) files such as HTML or graphics? To retrieve those results, you need to download the files from the SAS session to your local machine, where your application can access them. When you run a SAS program on a remote session, sometimes the expected result is more substantial than just a text-based listing. In that example, the only results I retrieved were the SAS log and SAS listing (text) output, if any. In a previous article, I described how to use Windows PowerShell to connect to a remote SAS Workspace, run a SAS program, and retrieve the results. ![]()
