如何使native native packager忽略某些目录

Question

问题:

我的项目有一个@providesModule naming collision尝试从命令行运行react-native run-ios.它与自动生成的dir冲突,dist/后者是由另一个npm包esdoc创建的.我希望能够保留这个自动生成的目录,并让反应原生包装器忽略该dist/目录.

错误信息:

[01/23/2017, 13:17:07] <START> Building Haste Map
    Failed to build DependencyGraph: @providesModule naming collision:
      Duplicate module name: ann
      Paths: /Users/thurt/projects/example/package.json collides with /Users/thurt/projects/example/dist/esdoc/package.json

This error is caused by a @providesModule declaration with the same name across two different files.

你几乎在https://github.com/facebook/react-native/issues/12131

您可以在项目根目录中创建一个metro.config.js使用(特定于版本)内容调用的文件,如下所示:

对于反应原生> = 0.57

const blacklist = require('metro-config/src/defaults/blacklist');

// blacklist is a function that takes an array of regexes and combines
// them with the default blacklist to return a single regex.

module.exports = {
  resolver: {
    blacklistRE: blacklist([/dist\/.*/])
  }
};

对于反应原生> = 0.52,<0.57

const blacklist = require('metro-config/src/defaults/blacklist');

// blacklist is a function that takes an array of regexes and combines
// them with the default blacklist to return a single regex.

module.exports = {
  resolver: {
    blacklistRE: blacklist([/dist\/.*/])
  }
};

对于React Native> = 0.46,<0.52.

const blacklist = require('metro').createBlacklist;

module.exports = {
  getBlacklistRE: function() {
    return blacklist([/dist\/.*/]);
  }
};

对于React Native <0.46.

const blacklist = require('metro-bundler').createBlacklist;

module.exports = {
  getBlacklistRE: function() {
    return blacklist([/dist\/.*/]);
  }
};

所有版本:

让CLI命令通过传递rn-cli.config.js选项使用此配置:

rn-cli.config.js

(NB可能是您需要传递rn-cli.config.js参数的错误,此位置可能应该自动加载但rn-cli.config.js优先级)

请注意,您的--config文件夹可能已被包装程序缓存,在这种情况下,您第一次运行它时可能需要重置缓存:

react-native run-ios --config=rn-cli.config.js
