Can't run flow in cmd when VS Code is open in Windows

[edele]

flow is running on a different directory.
server_root: c:\Users\edele\flowtest, client_root: C:\Users\edele\flowtest

1. Open VS Code in any project, wait flow to initialize
2. Run yarn run flow. It will fail with output:

C:\Users\edele\flowtest>yarn run flow
yarn run v1.7.0
$ C:\Users\edele\flowtest\node_modules\.bin\flow
flow is running on a different directory.
server_root: c:\Users\edele\flowtest, client_root: C:\Users\edele\flowtest
error Command failed with exit code 14.

I use cmd.exe in Windows 10.
I run flow in cmd to see all errors in a project, not just in open files.

Should it be fixed in flow-for-vscode extension or in flow-bin itself?
Is there a workaround?

[edele]

Looks like the issue originates in vscode.TextDocument.uri.fsPath which normalizes drive letter to lowercase according to documentation: https://code.visualstudio.com/docs/extensionAPI/vscode-api

[edele]

But the issue is not solved though. Does it impact anyone else?

Still thinking on a possible solution.

1. Should we force uppercase drive letter because flow-bin uses uppercase?
2. Should we change the way flow-bin decides if server_root and client_root are not the same just for Windows? (Windows paths are case-insensitive).

Same issue here.

Any workarounds?

[ArmorDarks]

I think there is none. Paths should be fixed in flow-for-vscode itself

Same issue here on Windows 10, when I'm using Linux Ubuntu 18.04 is work correctly. Anyone did find solution?

[edele]

We should do better path comparison in flow server for Windows as described here
facebook/flow#6592

Next little step would be to check if platform is win32 and lowercase path strings before comparing. It's ocaml tho 🐪

I have the same issue.
A dirty workaround would be to use the npm script "flow": "flow stop && flow ."
It works but the server is restarted both when launched from the command line and by the vscode plugin.

For me this was caused by a conflict with the flowtype v1.3.0 VSCode extension.
I gave up in the end and uninstalled the extension and flow worked as normal :/

@tomdbarker What is the exact issue you are facing?

[tomdbarker]

"flow is running on a different directory"

[Mayank1791989]

You are using wsl or normal shell?
