如何解决在将bcrypt添加到package.json时，使用docker节点alpine镜像出现“找不到任何Python安装”的问题？

pythonnode.jsdockerbcryptalpine-linux
36

在我的package.json中添加bcrypt之前，一切都正常。现在，我收到了以下错误消息。

这是我package.json的摘录：

  "dependencies": {
    "bcrypt": "3.0.6",
    "express": "^4.17.1",
    "mongodb": "^3.3.1",
    "nodemailer": "^6.3.0",
    "pm2": "^3.5.1",
    "redis": "^2.8.0",
    "xlsx": "^0.15.0"
  },

这是我的Dockerfile。我正在使用官方的Node Alpine镜像。我想知道Alpine是否已经安装了Python。


FROM node:13.5.0-alpine

WORKDIR /usr/app

COPY ./src .

RUN npm install

当我运行docker-compose时，出现了这个错误信息：

我该如何解决这个问题？我需要在Alpine上安装Python还是只需要添加环境变量？如果需要，请告诉我如何操作。我已经搜索了很多解决方案，但都没有成功...

人们喜欢使用阿尔卑斯基础镜像，因为它们非常小，由于它们非常小，所以不包含那些你没有明确安装的语言解释器等内容。 - David Maze

在 npm install 之前，在您的 Docker 文件中添加以下内容：
RUN apk add --update python make g++\
   && rm -rf /var/cache/apk/*

如果您正在使用Python 3，请记得使用python3而不是python。

实际上这就是正确的答案。npm会构建本地包，而node-gyp依赖于Python。此外，如果您不想在最终镜像中包含那些构建工具，您可以使用多阶段构建。https://docs.docker.com/develop/develop-images/multistage-build/ - Kennyhyun
我认为这个应该是被接受的答案，因为如果它在alpine镜像上运行，就不需要不必要地使用笨重的node镜像。但是目前在使用node:14-alpine版本时，它对我来说失败了。 - Vaulstein
Python2已经停止维护，现在唯一的选择是使用Python3。 - Vaulstein

以管理员权限打开PowerShell，并运行以下命令，然后安装bcrypt

Windows: npm install --global --production windows-build-tools

这仅适用于Windows。 - Jeremy

Linux Alpine是非常精简的镜像。如果性能不是限制，您可能希望考虑使用官方node镜像，它具有您所需的所有依赖项，只需担心开发：https://github.com/nodejs/docker-node因此，您可以拥有这样的Dockerfile：

FROM node:10
WORKDIR /usr/app
COPY ./src .
RUN npm install
EXPOSE 3000 # Use here the port you want to expose

不是最优解，但可能是最容易应用的答案。 - Timothy

为了完整起见：我解决了它。

解决方案是用 "bcryptjs" 代替依赖项 "bcrypt"。

使用bcryptjs没有错误。无论是标准的node docker镜像还是node alpine docker镜像都没有问题。

在Dockerfile中运行Node服务器的Compose文件 

FROM node:16.8.0-alpine
ENV SERVER_HOME=/usr/src/server/
WORKDIR $SERVER_HOME
COPY ./package*.json $SERVER_HOME
RUN npm install -g npm@7.24.0
RUN apk add --update python3 make g++ && rm -rf /var/cache/apk/*
RUN npm install
COPY . $SERVER_HOME
#EXPOSE 5000
CMD npm run build
CMD npm run start

在alpine镜像中安装node模块时遇到了问题，因为在alpine中找不到python，所以我使用python3运行它。 RUN apk add --update python3 make g++ && rm -rf /var/cache/apk/* 如果一切正常，那么一切都能够很好地工作。如果仍然出现问题，请把npm install替换为npm install --force。

阿尔卑斯山的正确解决方案是：

RUN apk add --no-cache python3 make g++

对我来说，问题出在pg-native依赖项上，node-gyp使用不正确。

从此链接中找到了解决方案 - node-gyp failure pg-native

以下是帮助的评论节选：

A：不要注意到错用了两个不同的数据库库：即pg和pg.js。

B：小心使用像sequelize这样的东西，您可能已经在初始化与DB的连接时标记了“本地”选项。这也经常会导致此错误。

C：最后，我经常完全删除pg-native库。它会引起奇怪的错误，这些错误与node-gyp不一致。
