1. VSCode下载安装
VSCode下载安装（链接：https://code.visualstudio.com/）特别简单，就如同普通软件安装到自己指定文件即可。
2. Fortran环境安装
通过Cygwin安装gfortran，可以参考博文Cygwin安装教程和Cygwin及Wget安装。博文VScode中配置使用fortran有更全面的介绍。
3. VSCode安装Fortran相关插件
四个插件：Fortran，Modern Fortran, Fortran IntelliSense, Code Runner, Fortran Breakpoint Support，其中Fortran Breakpoint Support插件是必须的，另一个插件是代码高亮的。还会有很多有趣插件，以后根据使用再进行添加。
4. 利用VSCode编写第一个Fortran程序
找个地方新建一个文件夹，文件结构如下：
└── hello├── hello.f└── .vscode├── launch.json└── tasks.json
在hello文件夹中新建一个.vscode的文件夹，注意文件夹前面的“点”，然后在.vscode文件夹中新建两个文件launch.json和tasks.json（源自：Guide_VSCode-fortran）。内容分别如下，
4.1 Windows系统
launch.json：
{"version": "2.0.0","configurations": [{"name": "Debug Fortran & build","type": "cppdbg","request": "launch","targetArchitecture": "x86","program": "${workspaceRoot}\\${fileBasenameNoExtension}.exe","miDebuggerPath": "gdb.exe","args": [],"stopAtEntry": false,"cwd": "${workspaceRoot}","externalConsole": true,"preLaunchTask": "build_gfortran"}]
}
tasks.json：
{"version": "2.0.0","_runner": "terminal","tasks":[{"label": "build_gfortran","type": "shell","windows": {"command": "gfortran"},"linux": {"command": "gfortran"},"osx": {"command": "gfortran"},"args": ["-g","${file}","-o","${workspaceRoot}\\${fileBasenameNoExtension}.exe"]}],
}
4.2 Linux
launch.json：
{// 使用 IntelliSense 了解相关属性。 // 悬停以查看现有属性的描述。// 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387"version": "0.2.0","configurations": [{"type": "cppdbg","request": "launch","name": "Debug","program": "${workspaceFolder}/${fileBasenameNoExtension}","args": [],"cwd": "${workspaceFolder}","preLaunchTask": "build"}]
}
tasks.json：
{"version": "2.0.0","tasks": [{"label": "build","type": "shell","command": "gfortran","args": ["-g","${fileDirname}/${fileBasename}","-o","${workspaceFolder}/${fileBasenameNoExtension}"]}]
}
在hello目录新建一个文件hello.f90，这个文件也可以在VSCode新建。
program HelloWorldprint *,'Hello,World!'read(*,*)
end
运行，Run或者Ctrl+F5
Windows
Linux
5. 出现问题汇总
gfortran : 无法将“gfortran”项识别为 cmdlet、函数、脚本文件或可运行程序的名称。请检查名称的拼写，如果包括路径，请确保路径正确，然后再试一次。
解决方法：将gfortran.exe文件夹添加到系统环境变量，如：C:\cygwin64\bin
After fixing “fortls could not be spawned” ide-fortran still not working
Error spawning fortls: Please check that fortran-language-server is installed and in your path.
解决方法：
安装Python3，执行pip install fortran-language-server
参考：FORTRAN IntelliSense extension (path) - Visual Studio Code
