well感谢您回答的每个人！最后，我提出了一个肮脏但有效的解决方案。整个问题是，在构建时间中，环境变量无法访问（除非您在dockerfile文件中使用arg和env参数，否您可能拥有的其他需要这些环境变量的服务都将在构建时间中失败。这个想法是，尝试调整代码，因此它不再丢弃错误，而是接受并管理这些ENV变量为null或未定义的情况。 例如，在数据库（Postgres）初始化文件（db/index.ts）中：
import { drizzle } from 'drizzle-orm/postgres-js';
import postgres from 'postgres';
import * as users from '$lib/server/db/schemas/users'
import * as normalized from '$lib/server/db/schemas/normalized'
import * as availability from '$lib/server/db/schemas/availability';
import * as lessons from '$lib/server/db/schemas/lessons';
import * as bookings from '$lib/server/db/schemas/bookings';
import { env } from 'process';
function createDb() {
const databaseUrl = env.DATABASE_URL;
console.log('DATABASEURL: ', databaseUrl)
if (!databaseUrl) throw new Error('DATABASE_URL is not set');
// Skip DB connection during build
if (process.env.NODE_ENV === 'build') {
console.log('Build mode - skipping database connection');
return null;
}
if (process.env.NODE_ENV === 'production') {
console.log('Production mode - skipping database connection');
}
const client = postgres(databaseUrl);
return drizzle(client, {
schema: { ...users, ...normalized, ...availability, ...lessons, ...bookings }
});
}
export const db = createDb();
然后，无论需要使用此DB，只需处理可能无法正确初始初始初始初始初始初始初始化的情况：
在Dockerfile中，您可以设置“构建”环境VAR仅能执行清洁逻辑：
# Build stage
FROM node:22-alpine AS builder
RUN corepack enable && corepack prepare pnpm@latest --activate
WORKDIR /app
COPY package.json pnpm-lock.yaml ./
RUN pnpm install
COPY . .
# Set build environment
ENV NODE_ENV=build
RUN pnpm build
# Production stage
FROM node:22-alpine
RUN corepack enable && corepack prepare pnpm@latest --activate
WORKDIR /app
COPY package.json pnpm-lock.yaml ./
RUN pnpm install --production
COPY --from=builder /app/build ./build
# Set production environment
ENV NODE_ENV=production
CMD ["node", "build/index.js"]
EXPOSE 3000
您只需要测试并尝试查看应用程序中的位置，其中有代码可能会在构建过程中造成冲突，然后调整逻辑以处理构建时间期间的非现有值。 我希望这对我处于同一情况的某人有效！
