Question

首先，我尝试了所有webpack error on build run. 'Error: Cannot find module '@webassemblyjs/ast''的答案，但是由于我使用了新的Webpack功能，因此无法降低Webpack版本。

我有一个现有的wep应用程序，正在尝试在新服务器上安装。在旧服务器和本地服务器上都运行良好。但是，我得到了一个运行CentOS的新VPS，并刚刚安装了node和npm。（使用https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-a-centos-7-server），它们似乎工作正常。所有模块似乎都正确安装。但是，当我尝试安装webpack时，出现了找不到@webassemblyjs/ast的错误。我实际上可以在我的node_modules目录中找到该文件。

我确认我在工作系统上具有完全相同的节点和npm版本。我尝试显式安装@webassemblyjs/ast，但没有任何区别。节点配置必须有一些软性问题，也许是在首次安装后需要执行一些额外的步骤。任何帮助将不胜感激。

找不到适用于Webpack的'@ webassemblyjs / ast'
