nodejs npm无法从github URL全局安装
我可以使用git URL在本地安装
如何直接从GitHub安装npm包？
但是，一旦我添加“-g”标志 – 失败。
这是整个日志

似乎EPEERINVALID错误与我一直试图完成的事情无关。 我在全球范围内卸载了“generaotr-express-angular”和“generator-angular”，它工作。
我现在的问题是
为什么这个无关的问题影响了我？ 如何避免它？
即使它失败了，Express仍然被安装。
NPM失败的原因是因为它对您本地安装的模块执行了健全性检查，并且该检查由于无效的对等关系（ 在此解释）而失败。 这个问题可能与Express没有直接关系，但是NPM不知道，所以我认为这个问题可能会导致问题，需要解决。 我也认为，你会安装的任何软件包，而不仅仅是Express，会引发同样的错误。
正如你已经发现的那样，删除有问题的软件包可以解决这个问题（另一种解决scheme可能是更新它们，前提是新版本可以解决这个问题）。 他们如何得到安装，我不知道。 也许他们安装了一个NPM版本，还没有对等关系parsing。
