问题 When I try to import a named import, it fails silently if the name import does not exist. Is there a way to get webpack to fail loudly when it cannot find the import at build time For example: // file1.js const var1 = 'var1' export { var1 } and // file2.js import { var2 } from './file1' // at this point, var2 is undefined at runtime because it was never exported from file1.js Instead, I want it to fail at build time. Is there a webpack option or some other technique I can use to catch this

问题 This question already has answers here : What is __init__.py for? (12 answers) Closed 5 years ago . I understand that python needs the __ init __.py file in order to recognize the directory as a python package, that way we can import sub modules into our program.I can see the similarity to classes and how init can be used to execute necessary code off the bat. However, in the python docs, this line confuses me, This is done to prevent directories with a common name, such as string, from

问题 I'd like to have modules/packages structure like following: /__init__.py /mymodule.py /mymodule/ /mymodule/__init__.py /mymodule/submodule.py And then use modules like: import mymodule import mymodule.submodule But it seems like file " mymodule.py " conflicts with " mymodule " directory. What's the correct naming convention here? 回答1: If you want to make a package, you have to understand how Python translates filenames to module names. The file mymodule.py will be available as the mymodule ,

问题 How do I make a C extension for python 3.x when a module has sub-modules? For example, I have a file called pet.c: #include <Python.h> PyObject* CatMeow(PyObject* self) { return PyUnicode_FromString( ">*<" ); } static PyMethodDef CatFunctions[] = { {(char*) "meow", (PyCFunction) CatMeow, METH_NOARGS, NULL}, {NULL, NULL, 0, NULL} }; static PyModuleDef CatDef = { PyModuleDef_HEAD_INIT, "cat", "cat ext", -1, CatFunctions, NULL, NULL, NULL, NULL }; PyMODINIT_FUNC PyInit_cat(void) { return

问题 I don't understand how module.exports can only export one component that has a dependency on a subcomponent but still be rendered in the DOM although that sub component was never exported. //component.js var SubComponent = React.createClass({ ... }); var Component = React.createClass({ ... render: function () { return( <div><SubComponent /> stuff</div>`) }}); module.exports = Component //main.js var Component = require('./component.js'); var MainContainer = React.createClass({ render:
