错误离子服务确实弹出未处理的例外：NGCC 失败
[英]ERROR Ionic serve does eject unhandled exeption: NGCC failed
问题描述
大家好 :) 从今天开始，我在为我的 ionic 项目提供服务时遇到了问题。 每次运行ng serve 、 ionic serve或npm run start出现相同的错误：
silasmartin@fd475edb-65e3-4754-a729-c2436b338573 heroes % ionic serve
> ng run app:serve --host=localhost --port=8100
[ng] Options:
[ng] --version Show version number [boolean]
[ng] -s, --source A path (relative to the working directory)
[ng] of the `node_modules` folder to process.
[ng] [default: "./node_modules"]
[ng] -p, --properties An array of names of properties in
[ng] package.json to compile (e.g. `module` or
[ng] `es2015`)
[ng] Each of these properties should hold the
[ng] path to a bundle-format.
[ng] If provided, only the specified properties
[ng] are considered for processing.
[ng] If not provided, all the supported format
[ng] properties (e.g. fesm2015, fesm5, es2015,
[ng] esm2015, esm5, main, module) in the
[ng] package.json are considered. [array]
[ng] -t, --target A relative path (from the `source` path) to
[ng] a single entry-point to process (plus its
[ng] dependencies).
[ng] If this property is provided then
[ng] `error-on-failed-entry-point` is forced to
[ng] true
[ng] --first-only If specified then only the first matching
[ng] package.json property will be compiled.
[ng] [boolean]
[ng] --create-ivy-entry-points If specified then new `*_ivy_ngcc`
[ng] entry-points will be added to package.json
[ng] rather than modifying the ones in-place.
[ng] For this to work you need to have custom
[ng] resolution set up (e.g. in webpack) to look
[ng] for these new entry-points.
[ng] The Angular CLI does this already, so it is
[ng] safe to use this option if the project is
[ng] being built via the CLI. [boolean]
[ng] --legacy-message-ids Render `$localize` messages with legacy
[ng] format ids.
[ng] The default value is `true`. Only set this
[ng] to `false` if you do not want legacy
[ng] message ids to
[ng] be rendered. For example, if you are not
[ng] using legacy message ids in your
[ng] translation files
[ng] AND are not doing compile-time inlining of
[ng] translations, in which case the extra
[ng] message ids
[ng] would add unwanted size to the final source
[ng] bundle.
[ng] It is safe to leave this set to true if you
[ng] are doing compile-time inlining because the
[ng] extra
[ng] legacy message ids will all be stripped
[ng] during translation.
[ng] [boolean] [default: true]
[ng] --async Whether to compile asynchronously. This is
[ng] enabled by default as it allows
[ng] compilations to be parallelized.
[ng] Disabling asynchronous compilation may be
[ng] useful for debugging.
[ng] [boolean] [default: true]
[ng] -l, --loglevel The lowest severity logging message that
[ng] should be output.
[ng] [choices: "debug", "info", "warn", "error"]
[ng] --invalidate-entry-point-manifest If this is set then ngcc will not read an
[ng] entry-point manifest file from disk.
[ng] Instead it will walk the directory tree as
[ng] normal looking for entry-points, and then
[ng] write a new manifest file.
[ng] [boolean] [default: false]
[ng] --error-on-failed-entry-point Set this option in order to terminate
[ng] immediately with an error code if an
[ng] entry-point fails to be processed.
[ng] If `-t`/`--target` is provided then this
[ng] property is always true and cannot be
[ng] changed. Otherwise the default is false.
[ng] When set to false, ngcc will continue to
[ng] process entry-points after a failure. In
[ng] which case it will log an error and resume
[ng] processing other entry-points.
[ng] [boolean] [default: false]
[ng] --tsconfig A path to a tsconfig.json file that will be
[ng] used to configure the Angular compiler and
[ng] module resolution used by ngcc.
[ng] If not provided, ngcc will attempt to read
[ng] a `tsconfig.json` file from the folder
[ng] above that given by the `-s` option.
[ng] Set to false (via `--no-tsconfig`) if you
[ng] do not want ngcc to use any `tsconfig.json`
[ng] file. [string]
[ng] --help Show help [boolean]
[ng] Unknown arguments: use-program-dependencies, useProgramDependencies
[ng] An unhandled exception occurred: NGCC failed.
[ng] See "/private/var/folders/nm/gndd82px52zfth8b5f54m4c00000gn/T/ng-Anv1eT/angular-errors.log" for further details.
[ERROR] ng has unexpectedly closed (exit code 127).
The Ionic CLI will exit. Please check any output above for error details.

请帮助我，即使将项目重置到最后一个工作点也没有帮助。 我尝试删除node_modules目录并使用npm install重新安装它或将"enableivy"=false添加到tsconfig.json 。 我不知道问题出在哪里。
感谢您的支持 :) Silas
