VSCode离线安装C/C++插件以及依赖包

网上有很多关于VSCode离线安装C/C++插件的博客，在这里我就不加累述了，其实完成这一步，插件还并不能正常使用。因为插件还有许多依赖包需要联网下载，如果电脑没有联网的话，将会下载依赖包超时Updating C/C++ dependencies... Downloading package Error:
解决办法如下：
1.找到你安装vscode.cpptools插件的目录：一般是C:\Users\用户名\.vscode\extensions\ms-vscode.cpptools-0.20.1
2.打开文件夹里的package.json文件，这个文件的最后几行有依赖包的下载路径：这些路径会随着版本的变化有所更新。我的package.json文件里下载路径如下：
3.其中Windows系统下的依赖包有：C/C++ language components (Windows)，ClangFormat (Windows)，Visual Studio Windows Debugger（我的下载链接：VSCode Cpptools依赖包）
4.解压这些文件，会出来三个文件夹：bin，debugAdapters，LLVM。把debugAdapters，LLVM这两个文件夹直接放在插件根目录一般是C:\Users\用户名\.vscode\extensions\ms-vscode.cpptools-0.20.1，把bin文件夹里的文件：Microsoft.VSCode.CPP.Extension.exe，Microsoft.VSCode.CPP.IntelliSense.Msvc.exe放到C:\Users\用户名\.vscode\extensions\ms-vscode.cpptools-0.20.1\bin文件夹下。
5.在插件根目录一般是C:\Users\用户名\.vscode\extensions\ms-vscode.cpptools-0.20.1，新建一个空的文件，文件命名为install.lock，为了给这些新的文件上锁。
6.大功告成，可以正常使用了！（不能上网的公司伤不起啊！！！）
