更新到最新的 Angular cli 版本后，NG v 仍然显示旧版本号？

Question

我已发出以下命令，如图所示。我收到一条成功消息，说 Angular cli 已更新到 10.0 版本。

\n

但是当我运行 ng v 命令时，我得到了旧版本号。

\n

那么它真的更新了吗？ \n这里有什么问题？\n如何全局更新到最新版本，以便当我通过 cli 生成新的 Angular 项目时，我可以在该项目中获得最新版本的 Angular ？

\n

\n

请注意-我已尝试关闭 cmd 并打开一个新的命令来检查ng v。还是一样。整个过程我做了两次。

\n

即使之后也无法工作npm cache clean force

我cmd在admin模式下打开，然后在那里更新了 Angular cli，它已成功更新，但是当我在正常模式下再次打开 cmd 时，它显示旧版本。

\n

所以我cmd以一种admin模式打开in my folder c:/users>ARPAN，我在那里更新了 Angular cli 版本，但它仍然显示相同的旧版本。请检查我附加的日志

最后！我能够解决这个问题。\n在管理模式下，在根 ( C:\\Users>) 文件夹中angular cli，版本是最新的，即10.0.1

\n

但是当我导航到was stillC:\\Users\\ARPAN>的版本时。angular cli8.3.3

\n

我无法弄清楚是什么导致了这个问题。我尝试了互联网上可用的所有内容和堆栈溢出。我尝试过npm cache clean --force npm cache verify。什么都没起作用。

\n

然后我做了以下步骤-

\n

然后我查看了里面，C:\\Users\\ARPAN>发现了一个package.json文件，其中的版本angular cli与8.3.3旧版本相同。

\n

\n
1. 我删除了那个。<<<<<<这是关键的一步。
\n
2. 然后我导航到C:\\Users\\ARPAN\\AppData\\Roaming\\npm-cache删除文件夹内的所有内容。
\n
3. 然npm uninstall -g @angular/cli
\n
4. npm cache clean --force
\n
5. npm install -g @angular/cli
\n

\n

它起到了魅力！这是日志！
