UnhandledPromiseRejectionWarning:错误:无法使用ext-gen找到模块
UnhandledPromiseRejectionWarning:错误:无法使用ext-gen找到模块
提问于 2019-02-16 22:53:15
我想开始使用ExtJS Community Edition。我遵循这个指令http://docs.sencha.com/extjs/6.6.0-CE/guides/getting_started/open_tooling.html。
我尝试执行命令：
ext-gen app -a但是，我有这个错误：
i [ext]: ext-gen: E:\/cool-universal-app created
i [ext]: ext-gen: package.json created for cool-universal-app
i [ext]: ext-gen: webpack.config.js created for cool-universal-app
i [ext]: ext-gen: npm install -s started for cool-universal-app
i [ext]: ext-gen: npm install -s completed for cool-universal-app
(node:4908) UnhandledPromiseRejectionWarning: Error: Cannot find module 'E:\cool-universal-app\node_modules\@sencha\ext\package.json'

E:\>npm -v

E:\>java -version

Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)怎么了？为什么会出现这个错误？怎样才能修复它？

看起来ext-gen中有一个包优先级问题，因为它需要提前安装两个sencha包，并抛出错误，因为它们不是。
Sencha仍然没有解决这个问题，所以我做了一个小的猴子补丁来解决它。因此，打开您的"C:\Users\pi\AppData\Roaming\npm\node_modules@sencha\ext-gen\ext-gen.js"，并在第597行之前添加以下行：
await util.spawnPromise(command, ['install', '@sencha/ext', '@sencha/cmd'], options, []);
最后，它必须看起来像这样：
await util.spawnPromise(command, ['install', '@sencha/ext', '@sencha/cmd'], options, []);
var frameworkPath = path.join(destDir, 'node_modules', npmScope, 'ext', 'package.json');
var cmdPath = path.join(destDir, 'node_modules', npmScope, 'cmd', 'package.json');页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
