当调用“发布”触发构建时,是什么控制传递给webpack的环境?看这个:
1>------ Build started: Project: MeshCut, Configuration: Debug Any CPU ------
1>MeshCut -> D:\MeshCut\bin\Debug\netcoreapp2.1\MeshCut.dll
2>------ Publish started: Project: MeshCut, Configuration: Debug Any CPU ------
MeshCut -> D:\MeshCut\bin\Debug\netcoreapp2.1\MeshCut.dll

Publish Succeeded.

第一行显然是调试版本,但这一行
node node_modules/webpack/bin/webpack.js --config webpack.config.vendor.js --env.prod
显然已通过env.prod
,这使得无法找出为什么从IDE运行服务器时不会发生生产错误的原因。
我尝试将环境变量ASPNETCORE_ENVIRONMENT设置为“开发”,但这没有帮助,可能是因为这是运行时。
最终这是msbuild的事情。 pubxml文件和csproj文件的组合是msbuild的输入。
csproj文件中的env.prod是文字。如果有某种方法可以使此值取决于构建类型(发布/调试),则可以解决问题。
还有另一个问题是从根本上相同的问题启发而来的,但提问者对发现自己可以通过编辑csproj来控制它感到满意。这对遵守发布/调试没有帮助。
这是MSBUILD的东西。这意味着在csproj文件中查找,并确保我们可以找到
<Target Name="PublishRunWebpack" AfterTargets="ComputeFilesToPublish">
<!-- As part of publishing, ensure the JS resources are freshly built in production mode -->
<Exec Command="npm install" />
<Exec Command="node node_modules/webpack/bin/webpack.js --config webpack.config.vendor.js --env.prod" />
<Exec Command="node node_modules/webpack/bin/webpack.js --env.prod" />
,很容易在第二个和第三个Exec语句中找到罪魁祸首。
剩下的问题是如何有条件地指定参数值,或者如何有条件地指定完全不同的命令行。
This Microsoft documentation似乎描述了第二种选择,但是msbuild不喜欢我用choose
和when
元素包装exec元素的尝试,我仍然可以使用一些帮助。

Exec支持Condition
属性。幸运的是,在CSPROJ文件的其他位置,目标之一已经取决于我们需要的确切条件。稍加复制/粘贴和调整,代码就变成...
