无法在 getRequiredModulePath 读取 NodeObject.getText 未定义的 属性 'text'

Question

生成浏览器应用程序包时出错（阶段：设置）。 什么会导致此错误？

来自控制台的信息：

Answer 1

angular 版本 12.2.12 和 12.2.11 中存在错误，使用 12.2.10 会修复它，或者您可能需要等待他们发​​布新版本或修复 12.2.12

注意：如果您在 package.json 文件中使用 ^12.0.1，请将其替换为 12.2.10

Answer 2

这似乎是由 12.2.11 中添加的 improved UMD module detection 引起的，将版本固定到 12.2.10 可以避免这个问题，但没有解决根本原因，即依赖项可能需要更新。

对我们来说，包裹是 @auth0/angular-jwt，但对您来说可能有所不同。为了找到它，我们必须使用 Linux 工具 strace 来找出在构建失败之前打开了哪个文件：

strace -f npm run build 2>&1 | egrep 'open|Error'

（最终）产生了输出

[pid 29550] open(".../node_modules/@auth0/angular-jwt/package.json", O_RDONLY|O_CLOEXEC) = 19
[pid 29550] open(".../node_modules/@auth0/angular-jwt/bundles/core.umd.js", O_RDONLY|O_CLOEXEC) = 19
[pid 29550] open(".../node_modules/@auth0/angular-jwt/bundles/core.umd.js", O_RDONLY|O_CLOEXEC) = 19
[pid 29550] open(".../node_modules/@angular/compiler-cli/bundles/ngcc/__ngcc_lock_file__", O_RDONLY|O_CLOEXEC) = 19
[pid 29550] write(2, "TypeError: Cannot read property "..., 1535TypeError: Cannot read property 'text' of undefined
[pid 29582] open(".../node_modules/@angular/compiler-cli/bundles/ngcc/__ngcc_lock_file__", O_RDONLY|O_CLOEXEC <unfinished ...>
[pid 29582] <... open resumed> )        = -1 ENOENT (No such file or directory)
[pid 29393] write(2, "(node:29393) UnhandledPromiseRej"..., 914(node:29393) UnhandledPromiseRejectionWarning: Error: NGCC failed.

错误模块在 运行 之前打开，更新它解决了问题。可能有更简洁的 shell 命令来获取错误，但这对我们来说已经足够了。
