It could be issue with your node version. I will suggest you to reinstall node and try it again.

您的节点版本可能有问题。我会建议您重新安装节点并重试。

Or you can also try to clean node cache of using npm cache clean --force

或者您也可以尝试清理使用的节点缓存 npm cache clean --force

First try updating NodeJS(8.9.3) and npm(5.6.0). These are the LTS versions. For Node this can be important! If that doesn't work, follow this installation guidefor windows.

首先尝试更新 NodeJS(8.9.3) 和 npm(5.6.0)。这些是 LTS 版本。对于 Node，这可能很重要！如果这不起作用，请按照此Windows安装指南进行操作。

Make sure you are not connected to VPN while installation is on.

确保在安装过程中您没有连接到 VPN。

Also, please cleanup your node_modules folder before your next try. I use the command rimraf node_modulesto remove this directory in windows.

另外，请在下次尝试之前清理您的 node_modules 文件夹。我使用命令rimraf node_modules在 Windows 中删除此目录。

Lastly try running npm install -g @angular/cli@latest

最后尝试运行 npm install -g @angular/cli@latest

run npm install -g @angular/cli@latestin command prompt as an admin.

以管理员身份在命令提示符中运行 npm install -g @angular/cli@latest。

right click the windows button, click on command propmt (Admin)or windows power shell(Admin)depending on your windows version. Then type the command and run it.

右键单击 Windows 按钮，根据您的 Windows 版本单击命令提示（管理员）或windows power shell（管理员）。然后输入命令并运行它。

Most times, you could get issues when you want to install as a normal user considering the fact that you are using the -g (global) flag.

大多数情况下，考虑到您正在使用 -g（全局）标志这一事实，当您想以普通用户身份安装时，您可能会遇到问题。

It is possible your npm cache has a corrupted file, perhaps it partially downloaded something and then got an error. Try npm cache clean --forceand see if that helps.

您的 npm 缓存可能有一个损坏的文件，也许它部分下载了某些内容然后出现错误。试试看npm cache clean --force是否有帮助。

If that doesn't help look in the log file given in the error message. Find the unexpected end of JSON inputmessage in the log file and look before it to see if there are any other hints to the problem.

如果这没有帮助，请查看错误消息中给出的日志文件。unexpected end of JSON input在日志文件中找到该消息并查看它之前是否有任何其他问题的提示。

You updated your question with a new error message. That one is more specific about the corrupted file. Try removing the cli-1.5.5.tgzfile from the path specified and try again. If you are using a web proxy on your network then it is also possible that your proxy has stored a corrupted cache: if you are able then turn off any proxies configured for your system and try a direct download.

您使用新的错误消息更新了您的问题。那个更具体地关于损坏的文件。尝试cli-1.5.5.tgz从指定的路径中删除文件，然后重试。如果您在网络上使用 Web 代理，那么您的代理也可能存储了损坏的缓存：如果可以，请关闭为您的系统配置的所有代理并尝试直接下载。
