Unable to install SQL Server (setup.exe), VS Shell installation has failed with exit code 1638.

solution

problem may be that there is an updated version of Visual C ++ Redistributable that SQL Server is trying to install, for example, from Visual Studio 2017. If you don’t need the latest C ++ Redistributable component, one way to resolve this problem is to add or remove programs and undistribute all references to Visual C ++ 2017 Redistributable. After this, the SQL Server installation should continue without error.

The problem is likely that there’s a newer version of the Visual C++ Redistributable than SQL Server is trying to install, e.g., from Visual Studio 2017. So another way to address this, if you don’t need the latest C++ redistributable, is to go to Add or Remove Programs and uninstall all references to Visual C++ 2017 Redistributable. After this, the SQL Server installation should proceed without errors.

About Xcode command phasescriptexecution failed with a nonzero exit code solution

1. Problem description

USES Xcode for code writing, and the following error has been reported during the compilation process when the new project code is pulled down during project development.

Command PhaseScriptExecution failed with a nonzero exit code

after searching on the Internet, most of the solutions given on the Internet were as follows. However, after I tried, the problem was not solved, but more mistakes were reported. Therefore, I consulted my tutor again, and finally got the solution.

encountered this bug hint when running a project, which could not be compiled. This is actually a bug caused by Xcode10. Solution: Select File -&gt in Xcode menu bar; Workspace Setting -> Choose Legacy Build System to rerun.

The primary cause of

is that the workspace is full, leading to code compilation errors, and there are roughly two ways to solve this problem.

(1) enter the code working cache folder of Xcode to clean manually ( is error-prone, is not recommended)

(2) use only the cleaning method provided by Xcode directly. Xcode will automatically link the working file after cleaning the workspace ( will not make mistakes, is recommended)

because the second method is easier to work with and less likely to go wrong, we use this method directly in the solution.

ii. Solution

1. First in Product -> Scheme selects the main code module for the current project

2. Select Product -> Clean Build Folder Clean workspace

3. Recompile the project code after

To solve the problem of loading rjava in installation of xlsx

[run target]

install

[error prompt]

solution 】 【 1, Java on the website to download the Windows version of the Java software

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

download download time attention to agree with statement after good Java installation
note:
if R is 64-bit, the installed Java must also be 64-bit and placed in C:\Program Files…
if you install C:\Program Files (x86), the system will continue to report the following error

2, download the Java, and install it, Under CMD, type
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_171
Path=C:\Program Files\Java\jdk1.8.0_171\bin
you can also manually set


3, finally re-run

Module build failed: SyntaxError: Unexpected token

vue router loading on demand times error 

{
	path: '/product',
	component: () => import('./pages/product'),
},

error: Module build failed: SyntaxError: Unexpected token

solution:

1. In the beginning, I was in a hurry to write something, but instead of studying it carefully, I changed it to another way: 
{
	path: '/product',
	component:resolve => require(['./pages/product'], resolve),
},

found no error and ran successfully. Later baidu checked that the original Babel needs to be added with syntax-dynamic-import plug-in, so that the Babel can correctly parse the syntax.

2. Download the plug-in 
npm install babel-plugin-syntax-dynamic-import --save-dev
3. Then modify the loader configuration

in webpack

{
	test: /\.js$/,
	loader:'babel-loader',
	options:{
		plugins:['syntax-dynamic-import']
	},
},

so far, problem solved

solution

looked at some of the solutions on the web, and finally solved by installing the full ruby.

: sudo apt install ruby

use the command sudo apt install ruby-full to install ruby, and then use the command sudo gem install sass to successfully install sass.

diff:

Replace the gem with the installation source

【Oracle】IMP-00010: not a valid export file, header failed verification

someone else gave an Oracle file, the result was found when importing the problem, the error was reported as follows:

IMP-00010: not a valid export file, header failed verification

after searching on the Internet, I found that it was caused by the version database problem. I opened the DMP file with UE editor and saw the first line as follows:

the figure above indicates that the database version is: Oracle12c version

use SQL:select * from v$version to query the current database version

we modified the TEXPORT:V12.02 of the DMP file to V11.02 and imported it again to solve the problem perfectly.
