制作一个码头形象，但得到一个npm错误！EXDEV

Question

我正在为一个小型个人项目开发一个API，而今天，当我试图组合docker容器时，我遇到了这个问题。

错误码

npm ERR! code EXDEV
npm ERR! syscall rename
npm ERR! path /usr/src/app/node_modules/aproba
npm ERR! dest /usr/src/app/node_modules/.aproba-zsSvSz54
npm ERR! errno -18
npm ERR! EXDEV: cross-device link not permitted, rename '/usr/src/app/node_modules/aproba' -> '/usr/src/app/node_modules/.aproba-zsSvSz54'

npm ERR! A complete log of this run can be found in:
npm ERR!     /root/.npm/_logs/2020-11-21T15_33_05_552Z-debug.log
ERROR: Service 'api-backend' failed to build : The command '/bin/sh -c npm install' returned a non-zero code: 238

此前(21-11-2020年)，一切都很顺利。但当我试图使用Bcrypt时，我开始发现错误。过了一段时间，我回过头来，突然间我犯了这个错误。我将链接我的对接-撰写和对接文件在下面。

我试着使用FROM node:14.15运行，这似乎是可行的。所以可能与最新的节点图像有关。

Answer 1

使用像FROM node:14.15这样的特定节点图像，而不是使用膝状体FROM node可以工作。
