我想在角度2中创建内置，我已经编写了 ng build --prod --aot 命令并获得了以下错误。

  180823 ms: Mark-sweep 1338.1 (1437.6) -> 1338.1 (1437.6) MB, 1325.4 / 0.0 ms [allocation failure] [GC in old space requested].

我还在项目中尝试了以下命令：

node --max-old-space-size=8192 node_modules/@angular/compiler-cli/src/main.js -p tsconfig-aot.json

并收到以下错误：

错误：ENOENT：没有这样的文件或目录，lstat'tsconfig-aot.json' 在错误（本机）在Object.fs.lstatSync（fs.js：982：18） at Object.main（/root/Desktop/rc1-dev/client/node_modules/@angular/tsc-wrapped/src/main.js:20:16）在main（/root/Desktop/rc1-dev/client/node_modules/@angular/compiler-cli/src/main.js:14:16）在对象。（/root/Desktop/rc1-dev/client/node_modules/@angular/compiler-cli/src/main.js:30:5）在Module._compile（module.js：570：32）在Object.Module._extensions..js（module.js：579：10）在Module.load（module.js：487：32）在tryModuleLoad（module.js：446：12）在Function.Module._load（module.js：438：3）编译失败

Answer 1

尝试通过以下脚本在包json中运行构建脚本：

{{1}}

然后运行“npm run build-prod”。

Answer 2

请勿使用angular-cli在制作中托管您的应用程序！

angular-cli developers do not recommend it as you can see here!

对于开发版本，您只需要1 GB内存，但生产版本非常耗费资源，可能需要2 GB以上的内存。

对于制作，您应该在具有超过2GB内存的PC中构建您的应用程序，并将/ dist文件夹传输到您的生产服务器。

对于您的生产服务器，您可以使用任何服务器。

如果您想坚持使用nodejs，我建议您使用saco在生产环境中托管您的单页Web应用程序。

Answer 3

使用ng build --prod --aot --no-sourcemap（非常确定 - 很多和   --no-sourcemap是默认情况下）为生产而构建。

Gzipping已从CLI本身中删除。你的网络服务器可以   为你处理gzipping或你可以管道gulp任务或   类似于在构建后压缩你的dist文件夹。

Answer 4

对于package.json中基于Webpack的应用程序>脚本，相应地增加值max_old_space_size = 5048。

"webpack-dev-server": "node --max_old_space_size=5048 node_modules/webpack-dev-server/bin/webpack-dev-server.js",
"webpack": "node --max_old_space_size=5048 node_modules/webpack/bin/webpack.js"
