Mongod binary installing in the wrong directory of workspace PNPM

Versions

• NodeJS: 14.16.1
• mongodb-memory-server-*: 7.0.0-beta.49
• mongodb(the binary version): 4.0.25
• mongoose: 5.12.15
• system: Windows 10

package: mongo-memory-server

What is the Problem?

MMS = mongodb-memory-server

I use MMS in a package of workspace and after installing dependencies and running a test script in the package, MMS tries to download the binary file. But if I run the test command from the root folder of the workspace, MMS can find the binary file from node_modules/.cache folder.

What I mean by root directory is: C:\Users\Sahin\projects\temp\mongodb-memory-server-issue-x And what I meant by package directory is: C:\Users\Sahin\projects\temp\mongodb-memory-server-issue-x\packages\my-app

Here is the folder structure:

Code Example

Here is the minimal repo https://github.com/seahindeniz/mongodb-memory-server-issue-489

Do you know why it happenes?

I’m not sure why, but I guess postinstall script installs the binary file to the upper node_modules folder rather than installing to the closest node_modules folder and using it from the closest node_modules. I guess it should work respectfully

closing, because workaround (PREFER_GLOBAL_PATH) works and wontfix label

I understand that MongoMS is now downloading and using the binary from temp folder- which I assume it is the default behavior of using preferGlobalPath option.

like i said earlier, this temporary directory is only for the DataBase Path, not the Binary or Download path

and preferGlobalPath will install it into the current users home directory (on POSIX systems, its ~/.cache/mongodb-binaries, and on DOS systems, its %USERPROFILE%/.cache/mongodb-binaries - both using os.homedir())

and as you can see by the output of

MongoMS:DryMongoBinary generateDownloadPath: Found binary in legacyHomeCache: "C:\Users\Sahin\.cache\mongodb-binaries\mongod-x64-win32-4.0.25.exe" +18ms

the binary is stored at C:\Users\Sahin\.cache\mongodb-binaries\mongod-x64-win32-4.0.25.exe
