将 git 设置为版本控制时，RStudio 给出“功能不正确”

Question

When I create a new project and select to create a new Git repository, or when I try to change the version control system in project options I receive a RStudio error stating "Incorrect function" with a big X and no extra information.

The below link has a similar issue, but their solution of changing the path for git.exe has not helped (i have tried all three paths)

Some extra notes:

• RStudio allows me to clone repository to set new working directory
• Also git works in bash, so i feel this is an RStudio issue.

Answer 1

I encountered the same error. For me it also had to do with using a network path not a local directory for the project location (as for lewis1211).

Workaround: Map the network drive. Eg Map your //server/share to some drive, say Z: (using map network drive, if you are using windows). If you set your project up under Z: then, it works.

Answer 2

If you have already chosen "git.exe" in RStudio --> Tools --> Global Options --> Git/SVN , then try to open Rstudio shell and type git init . In my case it showed "Permission denied", and after running as administrator the problem has gone.

Answer 3

This is only a partial answer if it fixes your problem: I reproduced this when trying to use a network path for a project location. When using a local directory no error occurs. Could indeed be an RStudio issue.

Answer 4

Run you R studio as Project administration. This solves my issue.

Answer 5

I have the same problem. The Git-RStudio-Connection fails but git is working perfectly in the CMD. When running the git init command in CMD it works and creates a .git folder. But running the git init command in the RStudio terminal fails with a message Warning: unable to access 'C:/Users/%username%/.gitconfig': Permission denied ... fatal: unknown error occured while reading the configuration files .

The Version Control Sytem (VCS) or git-Panel does not appear in RStudio and selecting it in the projects options leads to the same message Error: Unzulässige Function (eng. Error: Incorrect function ).

A closer look into the .gitconfig file should give you a new solution approach hopefully without having administration rights. Comparing the installation on the integration worksation with a productive workstation shows, that on the Test-Machine an incomplete.gitconfig file is on C:/Users/%username%/.gitconfig and on the Productive-Machine a complete gitconfig file is on Z:/.gitconfig . By the way, Z is a mapped drive which is linking to the company's user-profile settings (see CMD > echo %HOMEDRIVE% ).

According to this analysis there should be 2 possible solutions: (1) delete the .gitconfig and hope the the system is correctly looking into your profiles directory (2) complete the .gitconfig file that all necessary information are there. The message fatal: unknown error occured while reading the configuration files could actually be a hint, that the first message access... permission denied is false and the problem lies in the incomplete file.
