问题 I am newbie in all this stuff. Hope for your understanding. Let me clarify the issue: I am trying to start react native app through expo cli. So tried to start npm install expo-cli --global to install npm globally. I got this errors: Screen Screen_2 It also says that I lack permissions to access it. How can I allow permissions? Even when I try to start it locally I got the same issue. Your help is appreciated. Thanks:) 回答1: although this solution is not the best and the safest solution exists

问题 I have a simple C application: #include <stdio.h> int main() { printf("Hello, world!\n"); } When I: build this on an Apple Silicon device targeting arm64 using a build system that is compiled for x86_64 replace an existing binary (such as during a rebuild) The final binary cannot be executed and is reported as "killed" according to the shell: % rm hello # arch simulates the build system which is still compiled for x86_64 % arch -x86_64 cc -arch arm64 hello.c -o hello % ./hello Hello, world! %

问题 I have a basic C program: #include <stdio.h> int main() { printf("Hello, world!\n"); } When I compile this directly using cc on an Apple Silicon device, it produces an arm64 executable: % cc hello.c -o hello % file hello hello: Mach-O 64-bit executable arm64 % ./hello Hello, world! However, when I build it through a build system such as CMake or Ninja, it produces an x86_64 binary: % ./my-build-system % file hello hello: Mach-O 64-bit executable x86_64 I've verified that the command that the

问题 If adding user-defined library in Eclipse, one has an ability to set "Native library location". This field allows to enter some directory path. When does this path plays a part? 回答1: Eclipse uses this information to build the java.library.path when it launches a Java program. Background: Some Java frameworks depend on native code. This code usually comes in the form of a native shared library (*.so, *.dll). In Java, you can see methods with the attribute native . The code will load the shared
