Bug Summary
Clicking “Open AdminNeo” on any site repeatedly fails with an EINVAL error. The database browser never opens. The site itself runs normally.
Steps to reproduce
-
Install PowerShell 7 on Windows
-
Open Local and start any site
-
Click “Open AdminNeo” in the database section
-
AdminNeo fails to open — the following error appears in the Local log:
"code":"EINVAL","errno":-4071,"path":"C:\\Users\\FraserCampbell\\Welcome to PowerShell!\nC:\\Users\\FraserCampbell\\AppData\\Local\\Temp\\local-adminer-oxP-PcqqO-389611","syscall":"mkdir"
Environment Info
-
Windows 10 (build 26200) x64
-
MySQL 8.0.35
-
Local 10.0.0+6907
-
PowerShell 7.6.0 installed alongside Windows PowerShell 5.x
Root cause (identified)
main/_helpers/getWin32FullPath.js inside app.asar spawns powershell.exe to resolve the temp directory path, but passes only a minimal environment (missing process.env). This causes PowerShell to print its “Welcome to PowerShell!” banner to stdout, which gets captured and prepended to the actual path, producing an invalid directory name containing a newline character. This affects any Windows user with PowerShell 7 installed.
Suggested fix
const result = execFileSync('powershell.exe', ['-NoLogo', '-NonInteractive', '-Command', '(Get-Item -LiteralPath $Env:literalPath).FullName'], {
env: { ...process.env, literalPath },
}).toString().trim();
return result.split('\n').pop().trim();
