Question

我正试图制作电子应用。但是，我的工作一直停留在：require关键字给了我一个字符串，而不是模块对象。

electron = require('electron')
console.log(electron)

打印：

/path/to/my/project/node_modules/_electron@1.6.11@electron/dist/electron

，完全不能用作模块。

相比之下，如果我导入内置模块或其他npm安装的模块：

fs = require('fs')
console.log(fs)

mkdirp = require('mkdirp')
console.log(mkdirp)

它打印对象层次结构，包括变量和函数。

以下是选举目录的内容，我不知道他们是否健康：

$ ls node_modules/electron
appveyor.yml  cli.js  CONTRIBUTING.md  dist  electron.d.ts  index.js  install.js  issue_template.md  LICENSE  node_modules  package.json  path.txt  README.md  test

Answer 1

这是预期的行为。您需要使用电子（在node_modules / .bin中）运行您的应用程序，而不是普通节点。

这是official tutorial在package.json中使用的内容：

"scripts": {
  "start": "electron ."
}

最终调用electron cli，require使用Traceback (most recent call last): File "/Users/usernamehere/Desktop/Machine Learning/Lesson 5/CollaborativeFiltering/movies.py", line 32, in <module> cf = CollabFilterDataset.from_csv(path, 'ratings.csv', 'userId', 'movieId', 'rating') File "/Users/usernamehere/Desktop/Machine Learning/Lesson 5/CollaborativeFiltering/venv/lib/python3.6/site-packages/fastai/column_data.py", line 146, in from_csv df = pd.read_csv(os.path.join(path,csv)) File "/Users/usernamehere/Desktop/Machine Learning/Lesson 5/CollaborativeFiltering/venv/lib/python3.6/site-packages/pandas/io/parsers.py", line 709, in parser_f return _read(filepath_or_buffer, kwds) File "/Users/usernamehere/Desktop/Machine Learning/Lesson 5/CollaborativeFiltering/venv/lib/python3.6/site-packages/pandas/io/parsers.py", line 449, in _read parser = TextFileReader(filepath_or_buffer, **kwds) File "/Users/usernamehere/Desktop/Machine Learning/Lesson 5/CollaborativeFiltering/venv/lib/python3.6/site-packages/pandas/io/parsers.py", line 818, in __init__ self._make_engine(self.engine) File "/Users/usernamehere/Desktop/Machine Learning/Lesson 5/CollaborativeFiltering/venv/lib/python3.6/site-packages/pandas/io/parsers.py", line 1049, in _make_engine self._engine = CParserWrapper(self.f, **self.options) File "/Users/usernamehere/Desktop/Machine Learning/Lesson 5/CollaborativeFiltering/venv/lib/python3.6/site-packages/pandas/io/parsers.py", line 1695, in __init__ self._reader = parsers.TextReader(src, **kwds) File "pandas/_libs/parsers.pyx", line 402, in pandas._libs.parsers.TextReader.__cinit__ File "pandas/_libs/parsers.pyx", line 718, in pandas._libs.parsers.TextReader._setup_parser_source FileNotFoundError: File b'/Users/usernamehere/Users/usernamehere/Desktop/Machine Learning/Lesson 5/ratings.csv' does not exist到find the path to electron.exe（您发现的字符串），并将其作为运行该应用的子进程生成。

node.js require返回一个字符串而不是模块对象
