package ‘SparseArray’ not installed because it is not built for UCRT

本文讲述了用户在尝试安装R语言包SparseArray时遇到的问题,由于依赖的S4Arrays不可用,且不适用于UCRT。文章提供了使用BiocManager从源代码强制安装以解决此问题的方法。

今天下载SparseArray一直出现一个问题,如下

Error in unpackPkgZip(foundpkgs[okp, 2L], foundpkgs[okp, 1L], lib, libs_only,  : 
  package ‘SparseArray’ not installed because it is not built for UCRT

在Bioconductor下载了源码包也没法安装成功,出现

ERROR: dependency 'S4Arrays' is not available for package 'SparseArray'
* removing 'C:/Users/win10/AppData/Local/R/win-library/4.3/SparseArray'
Warning in install.packages :
  安装程序包‘C:/Users/win10/Downloads/SparseArray_1.2.4.tar.gz’时退出狀態的值不是0

解决方案

BiocManager::install('SparseArray',type="source"),指定从源代码安装,强制UCRT系统构建相应的二进制文件

### MSYS2 UCRT64 Environment Setup and Usage In the context of setting up an environment within MSYS2, particularly focusing on the UCRT64 variant, it is important to understand that this environment leverages Microsoft's Universal C Runtime (UCRT). This setup allows developers to compile applications using a more modern runtime compared to the older Mingw-w64 CRT used by MINGW64[^1]. To set up the UCRT64 environment: #### Installation Steps Ensure MSYS2 installation is complete. Open the MSYS2 terminal and update all packages with `pacman -Syu`. After updating, install necessary development tools specifically targeting the UCRT64 environment through the command line as follows: ```bash pacman -S mingw-w64-ucrt-x86_64-toolchain ``` This command installs essential components including compilers like GCC for building software under the UCRT framework. #### Verification Once installed, verify the presence of key executables such as gcc.exe or g++.exe inside the directory corresponding to the UCRT64 path typically located at D:\msys64\ucrt64\bin. #### Compilation Example For compiling simple programs after setting up the UCRT64 toolchain, use commands similar to those below from within the ucrt64 shell provided by MSYS2: ```cpp // hello.cpp #include <iostream> int main() { std::cout << "Hello, world!" << std::endl; return 0; } ``` Compile the program using G++ available in the UCRT64 environment: ```bash g++ -o hello hello.cpp ./hello ``` The above code snippet demonstrates how one might write and compile a basic C++ application intended to run natively against Windows' latest runtime libraries via the UCRT64 compiler suite. --related questions-- 1. What are the advantages of using UCRT over traditional MinGW-w64 CRT? 2. How does switching between different environments (MINGW32/MINGW64/UCRT64) affect cross-platform compatibility when developing applications? 3. Can projects built with UCRT64 be easily ported back to earlier versions of Windows without modification? 4. Are there specific features or optimizations enabled only in UCRT-based builds not present elsewhere? 5. In what scenarios would choosing UCRT64 over other options provide significant benefits during development?
