尝试在现有项目上设置 Angular App。在项目目录下 npm install 时，出现依赖项错误。

我使用 git 克隆了现有 angular 项目并设置了我的开发环境。仅供参考，我位于代理和防火墙后面。从我们的工件中获取节点模块。我已确保 .npmrc 文件指向正确的注册表。顺便说一句，我有不同的 .npmrc 文件。一个是项目的一部分，另一个在主目录下。两者都有一些不同，它们指向不同的内部工件。

Global =>
node -v 12.6.0
npm -v 6.9.0
Angular -v 8.1.2

Local Angular -v 7.3.9

ng version
Your global Angular CLI version (8.1.2) is greater than your local
version (7.3.9). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".    

Angular CLI: 7.3.9
Node: 12.6.0
OS: darwin x64
Angular: 7.2.15
... animations, common, compiler, compiler-cli, core, forms

不确定为什么我会收到 Python 错误，但在挖掘一些 npm 票证后，我也这样做了 - npm config set python "/usr/local/opt/python/libexec/bin/python" python -v 3.7.3
