Answer 1

您在这里收到的错误是：

Unexpected end of JSON input while parsing near '...omposition":"6.0.1-al'

此错误表示文件包含无效的JSON，但没有告诉您文件是哪个文件。

但是，因为它是npm，所以最有可能的候选者是package.json-在该文件中搜索“ 6.01-al”，看看是否可以找到错误。这几乎总是由手动编辑package.json文件中的依赖项引起的。

在这种情况下，错误似乎是文件已被截断，在这种情况下，它可能是您正在安装的软件包之一，无法正确下载或在途中已损坏。如果可以，请尝试将软件包安装在另一台计算机上。
