Question

问题：

从VS 2013升级到VS 2015后，我最初在构建应用程序时出现问题，但是通过设置msvs_version 2015解决了这个问题。虽然这适用于npm install（及其节点编译），但它在electron-rebuild阶段被忽略了。

详细说明：

初始问题

具体来说，我的构建过程曾经遇到过这个问题（我第一次升级时）： 22:07:39 c:\work-projects\my-application>c:\CM\elevated_cmd.exe /C "npm install > npm_install.log" 22:22:38 22:22:38 c:\work-projects\my-application>type npm_install.log 22:22:38 22:22:38 > libxmljs-mt@0.16.1 install c:\work-projects\my-application\node_modules\libxmljs-mt 22:22:38 > node-gyp rebuild 22:22:38 22:22:38 22:22:38 c:\work-projects\my-application\node_modules\libxmljs-mt>if not defined npm_config_node_gyp (node "C:\Program Files\nodejs\node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild ) else (node "" rebuild ) 22:22:38 Building the projects in this solution one at a time.

初始解决方案

但是这个命令设置可以很快解决这个问题： npm config set msvs_version 2015 --global

当前问题

一旦我设置了上面的命令，事情似乎工作正常。（npm install期间发生的初始编译开始正常工作）。但是一旦我到达使用electron-rebuild的构建部分，我发现返回相同的错误，但仅在电子重建编译期间，如下所示： 13:15:32 c:\work-projects\my-application>c:\CM\elevated_cmd.exe /C "gulp erebuild > erebuild.log" 13:16:05 13:16:05 c:\work-projects\my-application>type erebuild.log 13:16:05 [13:15:41] Using gulpfile c:\work-projects\my-application\gulpfile.js 13:16:05 [13:15:41] Starting 'erebuild'... 13:16:05 [13:15:41] Finished 'erebuild' after 394 ms 13:16:05 [13:16:04] Rebuilding modules against Electron didn't work: Error: gyp info it worked if it ends with ok 13:16:05 gyp info using node-gyp@3.6.2 13:16:05 gyp info using node@7.10.1 | win32 | x64 13:16:05 gyp http GET https://atom.io/download/electron/v1.8.2-beta.4/iojs-v1.8.2-beta.4.tar.gz 13:16:05 gyp http 200 https://atom.io/download/electron/v1.8.2-beta.4/iojs-v1.8.2-beta.4.tar.gz 13:16:05 gyp http GET https://atom.io/download/electron/v1.8.2-beta.4/SHASUMS256.txt 13:16:05 gyp http GET https://atom.io/download/electron/v1.8.2-beta.4/win-x64/iojs.lib 13:16:05 gyp http GET https://atom.io/download/electron/v1.8.2-beta.4/win-x86/iojs.lib 13:16:05 gyp http 200 https://atom.io/download/electron/v1.8.2-beta.4/win-x64/iojs.lib 13:16:05 gyp http 200 https://atom.io/download/electron/v1.8.2-beta.4/SHASUMS256.txt 13:16:05 gyp http 200 https://atom.io/download/electron/v1.8.2-beta.4/win-x86/iojs.lib 13:16:05 gyp info spawn C:\Python27\python.exe 13:16:05 gyp info spawn args [ 'c:\\work-projects\\my-application\\node_modules\\node-gyp\\gyp\\gyp_main.py', 13:16:05 gyp info spawn args 'binding.gyp', 13:16:05 gyp info spawn args '-f', 13:16:05 gyp info spawn args 'msvs', 13:16:05 gyp info spawn args '-G', 13:16:05 gyp info spawn args 'msvs_version=auto', 13:16:05 gyp info spawn args '-I', 13:16:05 gyp info spawn args 'c:\\work-projects\\my-application\\node_modules\\libxml-xsd\\build\\config.gypi', 13:16:05 gyp info spawn args '-I', 13:16:05 gyp info spawn args 'c:\\work-projects\\my-application\\node_modules\\libxml-xsd\\common.gypi', 13:16:05 gyp info spawn args '-I', 13:16:05 gyp info spawn args 'c:\\work-projects\\my-application\\node_modules\\node-gyp\\addon.gypi', 13:16:05 gyp info spawn args '-I', 13:16:05 gyp info spawn args 'C:\\Users\\MyBuilderUser\\.electron-gyp\\.node-gyp\\iojs-1.8.2-beta.4\\common.gypi', 13:16:05 gyp info spawn args '-Dlibrary=shared_library', 13:16:05 gyp info spawn args '-Dvisibility=default', 13:16:05 gyp info spawn args '-Dnode_root_dir=C:\\Users\\MyBuilderUser\\.electron-gyp\\.node-gyp\\iojs-1.8.2-beta.4', 13:16:05 gyp info spawn args '-Dnode_gyp_dir=c:\\work-projects\\my-application\\node_modules\\node-gyp', 13:16:05 gyp info spawn args '-Dnode_lib_file=C:\\Users\\MyBuilderUser\\.electron-gyp\\.node-gyp\\iojs-1.8.2-beta.4\\<(target_arch)\\iojs.lib', 13:16:05 gyp info spawn args '-Dmodule_root_dir=c:\\work-projects\\my-application\\node_modules\\libxml-xsd', 13:16:05 gyp info spawn args '-Dnode_engine=v8', 13:16:05 gyp info spawn args '--depth=.', 13:16:05 gyp info spawn args '--no-parallel', 13:16:05 gyp info spawn args '--generator-output', 13:16:05 gyp info spawn args 'c:\\work-projects\\my-application\\node_modules\\libxml-xsd\\build', 13:16:05 gyp info spawn args '-Goutput_dir=.' ] 13:16:05 gyp info spawn C:\Program Files (x86)\MSBuild\14.0\bin\msbuild.exe 13:16:05 gyp info spawn args [ 'build/binding.sln', 13:16:05 gyp info spawn args '/clp:Verbosity=minimal', 13:16:05 gyp info spawn args '/nologo', 13:16:05 gyp info spawn args '/p:Configuration=Release;Platform=x64' ] 13:16:05 Building the projects in this solution one at a time.

我对电子重建的大肆宣传非常简单明了，所以我怀疑它会揭示多少，但这里是：
```

gulp.task('erebuild', , function () {
    var eRebuild = require('electron-rebuild').rebuild;
    var arch = process.arch;
    eRebuild(
        {buildPath: __dirname,
            electronVersion: electronVersion,
            arch: arch
        })
        .then(function () {
            log('electron version: ' + electronVersion +  ' arch version: ' + arch);
            log('Electron Rebuild Successful');
            return true;
        }).catch(function (e) {
            log('Rebuilding modules against Electron didn\'t work: ' + e);
        });
});

```

我应该在我的electron-rebuild调用中添加一个选项来强制使用msvs_version值吗？

electron-rebuild不应该npm install自动使用此值吗？

我注意到electron-rebuild显示的gyp配置参数msvs_version=auto显示为其设置而非2015（请参阅“当前问题”部分中约1/3的方式以上）。如何指定auto /或指向2015的值（或如何让electron-rebuild明确使用2015而不是auto）？我不完全确定应如何处理这个问题。这是electron-rebuild中的错误吗？ electron-rebuild是否可以选择指定msvs_version？或者auto应该是我在配置中设置的值？如果是这样的话？

Answer 1

最后，尝试让electron-rebuild以某种方式查看npm msvs_version设置所设置的配置，无法解决此问题。在我的情况下，MS Visual Studio 2015和2017的工具集都在此过程中安装，似乎这些安装/卸载过程中的一些导致了问题。

我为解决此问题所做的是：

首先，我卸载了所有版本的MSBuild工具，MS Visual Studio （2015年和2017年，在我的情况下）甚至是Python。
然后我按照“Windows”特定说明的“选项1”进行操作 https://www.npmjs.com/package/node-gyp#installation通过做 npm install --global --production windows-build-tools
因为所有VS，MSBuild工具和Python都重新安装了 windows-build-tools包安装，Python设置似乎稍微不完整。为了解决这个问题，我做了以下事情：

a）配置Node以查看Python（运行npm config set python "C:\Users\MyUser\.windows-build-tools\python27\python.exe"）

b）设置PYTHON环境变量。您可以通过使用控制面板或在可以运行的高架CMD上执行此操作

set PYTHON "C:\Users\MyUser\.windows-build-tools\python27\python.exe"

之后，一切正常。

由'npm config set msvs_version 2015 --global`设置的标志不被电子重建
