npm error code EBADPLATFORM

[xuquankun]

Hello, I encountered such an error： $ npm install npm error code EBADPLATFORM npm error notsup Unsupported platform for @lancedb/vectordb-win32-x64-msvc@0.5.0: wanted {"os":"win32","cpu":"x64"} (current: {"os":"linux","cpu":"x64"}) npm error notsup Valid os: win32 npm error notsup Actual os: linux npm error notsup Valid cpu: x64 npm error notsup Actual cpu: x64 npm error A complete log of this run can be found in: /home/xqk/.npm/_logs/2024-06-26T02_51_09_436Z-debug-0.log

When I run the compiled exe file, and I get this error again, I see that you asked the same question under the vectordb project, how did you solve it?

Error: vectordb: failed to load native library. You may need to run npm install @lancedb/vectordb-win32-x64-msvc.

If that does not work, please file a bug report at https://github.com/lancedb/lancedb/issues

To resolve the npm error code EBADPLATFORM, follow these steps:

1. Conditional Dependency Installation: Modify package.json to conditionally install @lancedb/vectordb-win32-x64-msvc only on Windows.

"optionalDependencies": {
  "@lancedb/vectordb-win32-x64-msvc": "^0.5.0"
}

2. Platform-Specific Code: Ensure that any code requiring @lancedb/vectordb-win32-x64-msvc is conditionally executed based on the platform. Update Lance.ts to handle this.

import * as lancedb from "vectordb";
import { errorToString } from "../Generic/error";
import { EnhancedEmbeddingFunction } from "./Embeddings";
import CreateDatabaseSchema, { isStringifiedSchemaEqual } from "./Schema";

const GetOrCreateLanceTable = async (
  db: lancedb.Connection,
  embedFunc: EnhancedEmbeddingFunction<string>,
  userDirectory: string
): Promise<lancedb.Table<string>> => {
  try {
    const allTableNames = await db.tableNames();
    const intendedSchema = CreateDatabaseSchema(embedFunc.contextLength);
    const tableName = generateTableName(embedFunc.name, userDirectory);

    if (allTableNames.includes(tableName)) {
      const table = await db.openTable(tableName, embedFunc);
      const schema = await table.schema;
      if (!isStringifiedSchemaEqual(schema, intendedSchema)) {
        await db.dropTable(tableName);

        const recreatedTable = await db.createTable({
          name: tableName,
          schema: intendedSchema,
          embeddingFunction: embedFunc,
        });
        return recreatedTable;
      }

      return table;
    }

    const newTable = await db.createTable({
      name: tableName,
      schema: intendedSchema,
      embeddingFunction: embedFunc,
    });
    return newTable;
  } catch (error) {
    const errorMessage = `Error in GetOrCreateLanceTable: ${errorToString(
      error
    )}`;
    console.error(errorMessage);
    throw new Error(errorMessage);
  }
};

export const generateTableName = (
  embeddingFuncName: string,
  userDirectory: string
): string => {
  const sanitizeForFileSystem = (str: string) => {
    return str.replace(/[<>:"/\\|?*]/g, "_");
  };

  const directoryPathAlias = sanitizeForFileSystem(userDirectory);
  const sanitizedEmbeddingFuncName = sanitizeForFileSystem(embeddingFuncName);

  return `ragnote_table_${sanitizedEmbeddingFuncName}_${directoryPathAlias}`;
};

export default GetOrCreateLanceTable;

3. Script Adjustment: Ensure scripts/downloadOllama.js handles platform-specific binaries correctly.

const platform = os.platform();

if (process.argv[2] === "all") {
  Object.keys(binariesInfo).forEach(downloadIfMissing);
} else {
  downloadIfMissing(platform);
}

These steps should help resolve the platform-specific dependency issue.
