Error: SRC refspec master does not match any. error: failed to push some refs to

after being associated with the remote warehouse,

when we push the file from the local warehouse to the online warehouse through the push command

has the following error

error: src refspec master does not match any.

error: failed to push some refs to

common cause:

1. The local git repository directory is empty

2. Local warehouse add not commit

3. Git init error

use the command git add + file name , add the file to the repository, and then push normally.

here are some of the errors I made while operating.

****************************************************************************************

when add HTML files in a double 叒 error

and then use git status to check the file status, found that the three files are still associated with the remote warehouse SSH file, the original file path is wrong,

and then switch the path, git add file, push file to finally submit the local warehouse to the online warehouse

Load balancing failed to find a valid mailbox database

this period of time customer mail system upgrade, basically the same as before, CAS+HUB NLB, DAG database,

try creating a new mailbox. Error reporting

Load balancing failed to find a valid mailbox database.”

but if you choose a specific database it’s ok,

after the search reasons are as follows:

1) select update RU6

for exchange sp1

2) check to see if the database has dismount

3) mail database server not installed, but I think this should appear this error 🙂

Git error: unlink of file failed.Should I try again?

Error

occurs when git switches branches

Unlink of file ‘XXX’ failed.Should I try again?

at first thought that something had forgotten commit, but after this error occurred several times, it became clear that it wasn’t easy.

the reason is that you have some files in your working directory that are being used by a program, which is probably Idea,VS or eclipse, but it could also be another program

The

solution is not simply to choose y or n, but to close the IDE and let the IDE release the files.

can also be used in conjunction with Process Explorer on Windows to query which programs are using the file.

https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

if you switch back to the original branch, use git status to check for uncommitted files, then you can use 

git checkout -- *

the above command restores all these corrupted files to the last commit.

Cannot run program “make” when compiling APM firmware with eclipse under Windows: launching failed problem

1, as shown in the figure below, the Cannot run program “make”: Launching failed when setting up eclipse px4 compilation environment under Windows:

this problem occurs because the PATH of mak.exe is not included in the Windows PATH environment variable. Adding C:\pixhawk_toolchain\toolchain\bin to the PATH environment variable resolves this problem.

2. The python import error:No moudle named ’em’ will occur when executing the compile command again after adding the environment variable. The python package needs to be installed. Following the error prompt, the problem can be solved by recompiling the corresponding package after installing it by easy_install EMPy Catkin_pkg in the Windows command window.

3: ImportError: No module named ‘serial’ problem arises. The ImportError: No module named ‘serial’ problem requires the installation of the serial package. The ImportError problem can be resolved by running easy-install serial on the Windows command window and installing the serial package.

How to solve SVN authorization failed error

appears authorization failed exception, usually in the authz file or svnserv.conf, the user group or user authorization is not well configured, as long as the setting [/] can represent all the resources in the root directory, if you want to limit the resources, you can add the subdirectory.

the module was loaded but the call to DllRegisterServer failed with error code 0x80020009

1. Want to open the QQ space on the main panel, email, twitter, but click several times without any response, did not respond to a browser, the following solution, search on the net, http://jingyan.baidu.com/article/91f5db1bf5c3c61c7f05e3f0.html but directly on the run window type regsvr32
jscript. DLL, click “ok” appear the following error:

the

2.
the error above reference solve the: http://blog.csdn.net/woyaowenzi/article/details/4464588

Most probably, what you are trying to do is [ regsvr32 actxprxy.dll ].

For doing this, you will need to use a command prompt that is executed as administrator. So, grab your mouse… and

~ Right-click on the command prompt icon

~ Select [ Run as administrator ]

You may be prompted for administrator credential.

3. It says to run this command as Administrator. So don’t just run the window and type regsvr32 jscript.dll. Instead, type CMD, right-click on “Run as administrator” and open the black box command line window. Then type regsvr32
jscript.dll

4.
open QQ, then click the space button is ok.
