[Solved] Git error: refname refs/heads/master not found

Problems encountered

Create a project and associate it to a git remote warehouse

$ git init
$ git remote add origin [email protected]:abeelan/vue_demo.git
$ git branch -M main
$ git push -u origin main

Execute the third line of command, and an error occurs when changing the branch name

error: refname refs/heads/master not found
fatal: Branch rename failed

Solution:

$ git init
$ git remote add origin [email protected]:abeelan/vue_demo.git
$ git add .
$ git commit -m "demo finished"
$ git branch -M main
$ git push -u origin main

To modify the branch name, you need to have a commit before you can change it.

ASIC VCS Error: Error-[VCS_COM_UNE] Cannot find VCS compiler [Solved] 

[xxxx@localhost ~]$ vcs -h

Error-[VCS_COM_UNE] Cannot find VCS compiler
  VCS compiler not found. Environment variable VCS_HOME 
  (/opt/eda/synopsys/vcs-mx/N-2017.12-SP2/linux) is selecting a directory in 
  which there isn't a compiler 
  '/opt/eda/synopsys/vcs-mx/N-2017.12-SP2/linux/bin/vcs1' for a machine of 
  this type 'linux'.
  Please check whether 'VCS_HOME' is incorrect; if not, see below.

 Perhaps vcs hasn't been installed for machine of type "linux".
 Or the installation has been damaged.
 To verify whether vcsN-2017.12 supports machine of type "Linux 3.10.0-1160.31.1.el7.x86_64",
 please look at ReleaseNotes for more details .
 We determine the machine type from uname; maybe uname is incorrect.
 You can fix installation problems by reinstalling from CDROM 
 or downloading it from the Synopsys ftp server. 
 For assistance, please contact vcs technical support
 at [email protected] or call 1-800-VERILOG

Two solutions:

1. Specify VCs as 64 bit mode through the – full64 parameter

alias vcs ='vcs -full64'

2. Set VCS_ TARGET_ Arch is linux64

export VCS_TARGET_ARCH=linux64

If you instantiate tr and type TF, the fastest way to do this is to search the given prompt (usually in double quotes), and you’ll find a very low-level error. The error report will tell you which lines are wrong
