【问题描述】：
我打开 VS Code，然后我显示终端并打开 Powershell，到目前为止一切顺利。该应用程序也以管理员身份启动。然后我输入：
npm install -g yo generator-code
但它失败了。我不确定是什么，这是我第一次使用 npm，但是它不起作用，我知道很多。当我尝试 yo 代码时，它说 yo 无法识别。 上述命令输出以下“错误”：
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher. Older versions may use Math.random() in certain circumstances, which is known to be problematic. See https://v8.dev/blog/math-random for details.
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
changed 869 packages, and audited 870 packages in 1m

To address issues that do not require attention, run:
npm audit fix
To address all issues (including breaking changes), run:
npm audit fix --force
Run `npm audit` for details.
我看到了多个关于安装它的教程，但没有一个详细说明如果这样失败该怎么办。但我认为我应该运行 npm audit fix。但是在运行该命令时，它会给出以下输出：
npm ERR! code ENOLOCK
npm ERR! audit This command requires an existing lockfile.
npm ERR! audit Try creating one first with: npm i --package-lock-only
npm ERR! audit Original error: loadVirtual requires existing shrinkwrap file
npm ERR! A complete log of this run can be found in:

如果有帮助，这里是上面输出中提到的 debug.log 文件的内容：

正如我所说，这是我第一次使用 npm，所以我不知道这是什么，也不知道该怎么做。提前谢谢！
