npm 包似乎已损坏

Question

我收到这些警告，然后最后出现错误。什么是修复？

npm WARN deprecated core-js@2.6.10: core-js@<3.0 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.
npm WARN deprecated fsevents@1.2.9: One of your dependencies needs to upgrade to fsevents v2: 1) Proper nodejs v10+ support 2) No more fetching binaries from AWS, smaller package size

Answer 1

尝试删除package-lock.json然后npm install. 这对我有用：

cd <your-project-directory>
rm package-lock.json
npm install 

Answer 2

1. 删除package-lock.json

2. 删除node_modules，

3. 然后使用安装软件包npm install。

这为我解决了问题。

Answer 3

您需要禁用防病毒软件并以管理员身份运行cmd。不要忘记禁用 Windows 防火墙。至于已弃用的 Core-js 2.6.10，我面临着完全相同的问题，但至少这是一个您可以忽略的警告。我尝试重新安装 Angular cli 并手动将 Core-js 更新到最新版本，npm install -g core-js@latest不幸的是两者都不起作用。此外，fsevents 似乎与 Mac 相关，无需担心。
