清洁安装后npm安装失败，错误:找不到模块“我们还在吗？”

Question

我试图通过不同的方式更新npm (控制台和npm-windows-升级)，最终得到了多个安装，并决定卸载所有设备，清除路径，然后重新启动。

通过https://nodejs.org/en/的安装程序安装最新的lts版本后，将正确显示npm和节点版本。

node -v
v16.14.2

npm -v
8.5.0

现在运行npm install会导致错误

C:\Program Files\nodejs安装目录：

• C:\Program Files\nodejs\在路径上，没有其他nodejs或npm相关的

我有点不明白为什么国家预防机制找不到正确的模块。是否必须显式设置到nodejs目录的路径，是否存在上次安装遗留的配置文件冲突？

我想了解罪魁祸首，以便它可以正确地修复，而不会引起问题的全球安装软件包线。

控制台中运行的Npm实际上是与nodejs一起安装的：

PS C:\Users\Kilian\git\FooBar> gcm npm  

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Application     npm.cmd                                            0.0.0.0    C:\Program Files\nodejs\npm.cmd

Answer 1

在我的例子中，这个问题是在对一个新初始化的回购执行简单npm install之后自行解决的。我不知道这是否最终解决了这个问题，或者它是否是别的什么东西，但现在它又起作用了。

Answer 2

很好你解决了这个问题！

这可能与某些缓存问题或Packy-lock.json内容有关，下次发生时，您可以尝试删除锁文件和/或清理npm缓存。
