Angular npm install 有效，但 npm ci 出现错误

Question

我有一个托管 Angular 应用程序的 ASP.NET 核心应用程序的问题。

运行npm install正常，但npm ci不起作用并出现以下错误：

错误：

npm WARN prepare removing existing node_modules/ before installation
npm WARN lockfile Optional missing: fsevents@2.2.1
npm ERR! Cannot read property 'requires' of undefined

npm ERR! A complete log of this run can be found in:
npm ERR!     XX\_logs\2020-04-30T13_32_04_555Z-debug.log

调试日志文件：

我不知道该怎么做，以及为什么 install 有效但 ci 没有。有人能帮我弄清楚 npm ci 崩溃的原因以及我如何解决这个错误吗？

编辑： fsevents 被定义为一个可选的依赖项：

    "optionalDependencies": {
        "fsevents": "2.2.1",
        "node-sass": "4.12.0",
        "protractor": "5.4.2",
        "ts-node": "8.4.1",
        "tslint": "5.20.0"
    }

所以我认为-no-optional国旗会有所帮助。我 nuked node_modules 和 package-lock.json 运行npm install -no-optional，然后npm ci -no-optional. 除了运行安装时的一堆警告（见下文）外，我遇到了与上面相同的错误。

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: abbrev@1.1.1 (node_modules\@angular\compiler-cli\node_modules\fsevents\node_modules\abbrev):
npm WARN enoent SKIPPING OPTIONAL DEPENDENCY: ENOENT: no such file or directory, rename 'XX\ClientApps\node_modules\@angular\compiler-cli\node_modules\fsevents\node_modules\abbrev' -> 'XX\ClientApps\node_modules\@angular\compiler-cli\node_modules\fsevents\node_modules\.abbrev.DELETE'

添加了以下日志记录/输出：

检查package-lock.json中的fsevents版本是否与package.json中的不匹配

npm ci 从 package-lock.json 进行验证。如果版本不匹配，它将退出并出现错误。但 npm install 只会查看 package.json 并开始将它们添加到 node_modules 中。如果 package-lock.json 中未提及版本，它将由 npm install 自动添加
