问题 This is going to be a short question. The source is here: https://github.com/exhuma/grc And the title explains my problem ;) I registered and uploaded the package to pypi . Now if I run easy_install grc , it works as expected. But if I run pip install grc , it installs properly, but does not install the data_files. I don't see why this is happening. Any ideas? 回答1: Maybe the files aren't installed in the path you expect. In Ubuntu 11.10, I see them under /usr/local/configs as it can be seen

问题 I'm making an Rails API call and return a single JSON object that has a nested User Object and a tag list array. However, I can't access the nested Object. this.props.post.user.name throws: Cannot read property 'name' of undefined. I am confused because when I make the call to PostsIndex in PostsIndex.js and get an array of objects and map through it I can access everything. Is there something I need to do when only dealing with a single object? PostShow.js import React, {Component} from

问题 I am trying to use Tailwind CSS in an Next.js project but I cant't use my Tailwind classes with Next.js Image component. Here's my code: <Image src={img.img} alt="Picture of the author" width="200" height="200" className="bg-mint text-mint fill-current" ></Image> I want to use Tailwind classes instead of the height and width property of the Next.js Image. But I can't because it throws me an error. Also, unsized property throws another error saying it's deprecated. Is there any solution? Here

问题 I'm trying to know whether it's possible to export/copy dependencies of a project managed using Maven while maintaining the folder structure that is adopted in the local repository. The root of my need is that I have amassed through almost ten years a lot of artifacts in my local repository (~8GB). I am no longer working on those old projects from previous assignments that drew most of the artifacts in and now, I need to move just what is needed for one single project (~650MB of artifacts) to

问题 What is the order of constructor call in virtual inheritance in c++? For the following two cases of multiple inheritance; (I) for the following code, without virtual inheritance; class a { public: a() { cout<<"\t a"; } }; class b: public a { public: b() { cout<<"\t b"; } }; class c: public b { public: c() { cout<<"\t c"; } }; class d: public c { public: d() { cout<<"\t d"; } }; class e: public c, public d { public: e() { cout<<"\t e"; } }; class f: public b, public e { public: f() { cout<<"\t

问题 I have set up postfix on a server, along with openDKIM. When I run: echo "Testing setup" | mail -s "Postfix test" {my_email_address} I get the email, and in the mail headers there is a DKIM-Signature header. When, however I write a python script to send an email, using smtplib: import smtplib from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart from email.utils import make_msgid msg = MIMEMultipart('alternative') part1 = MIMEText('Hello, world', 'plain') msg

问题 I need to apply a filter on an attribute of an optional table produced by a left join in scala slick . I could not find any documentation on this or any similar questions online. Consider the following query: val query = FirstTable joinLeft SecondTable on (_.foreignId === _.id) I would like to filter is by an attribute of the SecondTable : query.filter { case (firstTable, secondTableOpt) => secondTableOpt.attribute === "value" } Obviously this does not compile since secondTableOpt is a Rep
