I am trying to develop with Salesforce DX. There is a new problem since I restarted this project after a two-month break. Every variation of the auth:web:login command fails the same way. force:org:list also elicits the same error. My environment is Ubuntu 16.04 (Linux). What to do? Terminal session:

me@here:~/Projects/sfdx-simple$ sfdx force:auth:web:login

TypeError: ts_types_1.getString is not a function at AuthWebLoginCommand.catch (/usr/local/lib/sfdx/node_modules/salesforce-alm/dist/ToolbeltCommand.js:172:24) at AuthWebLoginCommand._run (/usr/local/lib/sfdx/node_modules/@salesforce/command/lib/sfdxCommand.js:95:29)

    Have you tried sfdx update followed by sfdx plugins:update? This can often resolve most runtime issues.

  • Tried it but it had no effect, which makes sense, since it is a recent re-install of Node, Salesforce CLI, and sfdx .

  • BTW this works fine on my Windows 10 system. I will test on other Ubuntu 16.04 machines.

  • Commands work normally on another machine with a fresh install of sfdx on Ubuntu 16.04. That install brought Node 15.10.3 with it. The problem machine also has Node 16.0 and I suspect there is a snafu amongst the installations and re-installations of Node, and/or nvm, npm, vsCode, sfdx, and the vsCode extensions. Time to burn it all with a blowtorch and re-install!

  • It works, after a thorough cleaning and re-install!

Got something similar:

ts_types_1.has is not a function


I had to uninstall the Salesforce CLI and reinstall to resolve the error.

  • This worked for me. May be some issue between the CLI extension in VS Code and the CLI program. Whatever it is, uninstall/reinstall fixed it.

I deleted nvm, npm, vsCode, Node, and sfdx. I uninstalled what I could, and deleted all files that remained. Then I reinstalled vsCode, sfdx, the vsCode extensions, and Node 15.10.3 . Once I did that, it all worked again. So I don't know what was wrong, but I suspect that there is an incompatibility with Node 16.0 . I usually follow these rules: Never install a ".0" release (Node 16.0), and, Never install software that isn't required (nvm, npm).
