Angular 4：ng服务正常，但是ng build --prod失败

Question

When I tried to run ng serve it runs without any error, but when I tried to create a production build using ' ng build --prod ' it stopped with error below. I tried to tweak with the version still no success. Then some other issue occurred like other API version compatibility issue. Any help will be highly appreciated.

ERROR in ./src/main.ts Module not found: Error: Can't resolve './$$_gendir/app/app.module.ngfactory' in 'D:\\000PS\\workspace_ui\\dashboard\\src' ERROR in Error: Metadata version mismatch for module D:/000PS/workspace_ui/dashboard/node_modules/ngx-pipes/src/app/index.d.ts, found version 4, expected 3 at StaticSymbolResolver.getModuleMetadata (D:\\000PS\\workspace_ui\\dashboard\\node_modules\\@angular\\compiler\\bundles\\compiler.umd.js:25755:34) at StaticSymbolResolver._createSymbolsOf (D:\\000PS\\workspace_ui\\dashboard\\node_modules\\@angular\\compiler\\bundles\\compiler.umd.js:25543:46) at StaticSymbolResolver.getSymbolsOf (D:\\000PS\\workspace_ui\\dashboard\\node_modules\\@angular\\compiler\\bundles\\compiler.umd.js:25524:14) at D:\\000PS\\workspace_ui\\dashboard\\node_modules\\@angular\\compiler\\bundles\\compiler.umd.js:24381:30 at Array.forEach () at extractProgramSymbols (D:\\000PS\\workspace_ui\\dashboard\\node_modules\\@angular\\compiler\\bundles\\compiler.umd.js:24380:79) at AotCompiler.analyzeModulesAsync (D:\\000PS\\w orkspace_ui\\dashboard\\node_modules\\@angular\\compiler\\bundles\\compiler.umd.js:23936:47) at CodeGenerator.codegen (D:\\000PS\\workspace_ui\\dashboard\\node_modules\\@angular\\compiler-cli\\src\\codegen.js:32:14) at Function.NgTools_InternalApi_NG_2.codeGen (D:\\000PS\\workspace_ui\\dashboard\\node_modules\\@angular\\compiler-cli\\src\\ngtools_api.js:73:30) at _donePromise.Promise.resolve.then (D:\\000PS\\workspace_ui\\dashboard\\node_modules\\@ngtools\\webpack\\src\\plugin.js:428:58) at at process._tickCallback (internal/process/next_tick.js:188:7)

Answer 1

Your angular version is 4.4 and ngx-pipes angular version is 5 or above. So install ngx-pipes with version that is compatible with your angular project.

Check inside node_modules/ngx-pipes/package.json to find ngx-pipes version.
