nodejs npm 无法从 github URL 全局安装

Question

我可以使用 git URL 在本地安装

How to install an npm package from GitHub directly?

但是，一旦我添加“-g”标志 - 它就会失败。

这是整个日志

编辑：

似乎EPEERINVALID 错误与我一直试图完成的事情无关。我全局卸载了“generaotr-express-angular”和“generator-angular”，它工作正常。

我现在的问题是

为什么这个不相关的问题会影响到我？如何避免？

尽管它失败了，但从外观上看，Express 仍然安装了。

NPM 失败的原因是它对本地安装的模块执行完整性检查，并且由于无效的对等依赖关系而导致检查失败（解释为 here）。该问题可能与 Express 没有直接关系，但 NPM 并不知道这一点，因此我认为它会假定该问题可能会导致问题，并且需要解决该问题。我还认为您将安装的 任何 软件包，而不仅仅是 Express，都会触发相同的错误。

正如您已经发现的那样，删除有问题的软件包可以解决问题（另一个解决方案可能是更新它们，前提是更新的版本可以解决问题）。他们最初是如何安装的，我不知道。也许他们安装了一个 NPM 版本，还没有对等依赖解析。
