syntaxhighlighter - 构建:loadReposFromCache(...)。错误不是函数

我正在尝试使用插件SyntaxHighlighter v4,但我无法让构建过程正常工作!

按照说明here,我收到以下错误:

$ ./node_modules/gulp/bin/gulp.js setup-project

似乎没有将github存储库文件导入/repos/目录。我能以某种方式手动完成此操作吗?是否有另一种方法来构建这样我可以使用它?甚至可以找到像v3中那样构建的文件?

以下是build/setup-project.js

中失败的功能
gulp.task('setup-project:clone-repos', 'Clones all repositories from 
  SyntaxHighlighter GitHub organization', () =>
    loadRepos()
      .then(R.filter(repo => !fs.existsSync(pathToRepo(repo))))
      .then(R.filter(repo => repo.name !== 'syntaxhighlighter'))
      .then(R.map(R.curry(cloneRepo)))
      .then(Promise.all)
);

向后追溯我们看到:

const loadReposFromCache = () => fs.readFile.promise(REPOS_CACHE, 'utf8').then(JSON.parse);
const loadRepos = () => loadReposFromCache().error(loadReposFromGitHub).then(R.map(R.pick(['clone_url', 'name'])));

function loadReposFromGitHub() {
  const request = require('request');

  const opts = {
    url: 'https://api.github.com/orgs/syntaxhighlighter/repos?per_page=300',
    json: true,
    headers: { 'User-Agent': 'node.js' },
  };

  return new Promise((resolve, reject) =>
    request(opts, (err, response) => {
      if (err) return reject(err);
      const json = response.body;
      fs.writeFile(REPOS_CACHE, JSON.stringify(json, null, 2));
      resolve(json);
    })
  );
}

2 个答案:

答案 0 :(得分:3)

该项目的构建代码中存在一些问题。

对于这里的具体问题,Bluebird承诺上的Songbird包装似乎不再匹配 - 因此“.error不是一个函数”(在鸣鸟上,但在蓝鸟上确定)。

所以用.error替换.catch或用require('songbird')替换require('bluebird')

在任何一种情况下,这只是构建困境的开始......

无论如何,我已将此添加到项目的问题跟踪中,但这是我为了获得它而采取的措施: https://github.com/karljacuncha/syntaxhighlighter/commit/dc015fa299d4d249e8518664e205a838c55372cf

答案 1 :(得分:1)

构建再次中断(2021 年 4 月)。我将项目从 karljacuncha's answer 分叉,并将 fs.writeFile 的调用更改为 fs.writeFileSync

我还修复了我在更大社区中发现的其他修复程序,并且还修复了 -output 参数的使用。
