将 bcrypt 添加到 package.json 时，如何使用 docker node alpine Image 解决“找不到任何要使用的 Python 安装”？

Question

在我将 bcrypt 添加到我的 package.json 之前，一切正常。现在，我收到以下错误消息。

这是我的 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。我正在使用官方节点高山图像。我想知道 alpine 是否已经安装了 phyton。

FROM node:13.5.0-alpine

WORKDIR /usr/app

COPY ./src .

RUN npm install

我在运行 docker-compose 时收到此错误消息：

我该如何解决这个问题？我必须在 alpine 上安装 phyton 还是只添加 env 变量？如果是这样，请告诉我如何。我已经在寻找解决方案，但没有人工作......

Answer 1

以管理员权限打开Powershell并运行此命令，然后继续进行bcrypt安装

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

Answer 2

Linux Alpine 是非常简约的图像。如果性能不是限制，您可能需要考虑使用具有您需要的所有依赖项的官方节点映像，只需担心开发：https : //github.com/nodejs/docker-node 所以，您可以拥有一个Dockerfile像这样：

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

Answer 3

在 npm install 之前将其添加到您的 docker 文件中：

RUN apk add --update python make g++\
   && rm -rf /var/cache/apk/*

Answer 4

在 Dockerfile 中编写文件以运行节点服务器

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

我在 alpine 映像中安装节点模块时遇到问题，因此在 alpine 中找不到 python，因此我使用 python3 RUN apk add --update python3 make g++ && rm -rf /var/cache/apk/* 运行此命令，一切正常如果您仍然遇到问题，请将 npm install 替换为 npm install --force

Answer 5

Alpine 的正确解决方案是

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

Answer 6

为了完整起见：我解决了它。

解决方案是将依赖项“bcrypt”替换为“bcrypt js ”。

使用 bcryptjs 没有错误。无论是标准节点 docker 镜像还是节点 alpine docker 镜像。

Answer 7

我通过从 https://www.python.org/downloads/windows/下载并安装 python 解决了这个问题
