Angular CLI在我"服务"时给了我"TypeError:callbacks [i]不是函数"

Question

我刚刚完成了Angular CLI的全新安装,以便尝试一下,我不知道在命令行上导致以下错误的原因:

    PC:cobros Fran$ ng serve
** NG Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200/ **
 95% emitting/Users/Fran/Documents/Workspace/Repos/cobros/node_modules/enhanced-resolve/lib/CachedInputFileSystem.js:40
        callbacks[i](err, result);
                    ^

TypeError: callbacks[i] is not a function
    at Storage.finished (/Users/Fran/Documents/Workspace/Repos/cobros/node_modules/enhanced-resolve/lib/CachedInputFileSystem.js:40:15)
    at /Users/Fran/Documents/Workspace/Repos/cobros/node_modules/enhanced-resolve/lib/CachedInputFileSystem.js:77:9
    at /Users/Fran/Documents/Workspace/Repos/cobros/node_modules/graceful-fs/polyfills.js:287:18
    at FSReqWrap.oncomplete (fs.js:153:5)

这是我在尝试"ng -v"时返回的信息(如果它有用的话):

Angular CLI: 1.6.8
Node: 8.9.0
OS: darwin x64
Angular: 5.2.4
... animations, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, router

@angular/cli: 1.6.8
@angular-devkit/build-optimizer: 0.0.42
@angular-devkit/core: 0.0.29
@angular-devkit/schematics: 0.0.52
@ngtools/json-schema: 1.1.0
@ngtools/webpack: 1.9.8
@schematics/angular: 0.1.17
typescript: 2.5.3
webpack: 3.10.0

"增强型解决"模块甚至做了什么？我安装角度错了吗？我按照https://github.com/angular/angular-cli的说明操作,确保我满足了先决条件.

编辑:问题现已修复,因此不再需要使用此解决方法.

在此处找到解决方案(解决方法)

添加"copy-webpack-plugin": "4.3.0"到你的package.json

谢谢@neshkatrapati

Answer 2

我有同样的问题,这个命令对我来说是奇迹

npm install copy-webpack-plugin@4.3.1

Answer 3

编辑:问题现已修复,因此不再需要使用此解决方法.

升级@angular/cli到之后会发生1.6.8.

解决方案:问题出在copy-webpack-plugin(https://github.com/webpack-contrib/copy-webpack-plugin/issues/217) npm i copy-webpack-plugin@4.3.1 --save-dev帮助

注意:以前提供的解决方案是将cli降级到1.6.7,这没有帮助.

Answer 4

现在应该使用刚刚发布的v4.4.1解决此问题. https://github.com/webpack-contrib/copy-webpack-plugin/releases/tag/v4.4.1
