Your requirements could not be resolved to an installable set of packages about php-bitcoinrpc

[denpamusic]

Try adding version constant when requiring package
(e. g. run composer require denpa/php-bitcoinrpc "^2.0")

If this doesn't help, try running composer clear-cache && composer update.

After I run the command ,It still shows the same error。
What should I do with it?

[1281152329]

when i try running composer update,it shows the error.like running composer resquire.
"Installation failed, reverting ./composer.json to its original content."

[denpamusic]

OK. Can you please run composer --version and post it's output here. I'll try to replicate your error.

Composer version 1.6.5
我又遇到了一个麻烦，天呐
上午的时候我重新从git上下载了一份代码，然后重新composer，结果
Your requirements could not be resolved to an installable set of packages.

Problem 1

- Can only install one of: denpa/php-bitcoinrpc[v2.0.1, dev-master].
- Can only install one of: denpa/php-bitcoinrpc[v2.0.2, dev-master].

Installation failed, reverting ./composer.json to its original content.
虽然我根本没有装成功但是我尝试去删除这个依赖
但是它提示我
Package "denpa/php-bitcoinrpc" listed for update is not installed. Ignoring.
然后重新装勒composer但是还是没有用
我被困在这儿了

I'm sorry, I'll say it again in English.
I have a trouble again, oh my god.
In the morning, I downloaded the code from GIT and restarted composer.the result is:
Your requirements could not be resolved to an installable set of packages.Problem 1

• Can only install one of: denpa/php-bitcoinrpc[v2.0.0, dev-master].
• Can only install one of: denpa/php-bitcoinrpc[v2.0.1, dev-master].

Installation failed, reverting ./composer.json to its original content.

Although I didn't succeess, I tried to delete this dependency.
But it hints me:
Package "denpa/php-bitcoinrpc" listed for update is not installed. Ignoring.
So,i have to uninstall composer and Reinstall it ，but there is no use
what should i do?
I'm very confused

[denpamusic]

To delete dependency, open composer.json find 'require' section, that looks like this

"require": {
    ...
    "denpa/php-bitcoinrpc": "...",
    ...
},

delete string that starts with "denpa/php-bitcoinrpc".
Finally delete composer.lock file and run composer update.

[denpamusic]

If possible it's will also be great if you can post your composer.json file here(at least "require" and "require-dev" section of it). If it contains any private information you can of course delete it.

[1281152329]

my composer.json file is the same as yours

[1281152329]

first,i delete string that starts with "denpa/php-bitcoinrpc". and delete composer.lock file
second,i composer update,It's normal.
third，i coomposer require denpa/php-bitcoinrpc，
the question continued；
composer.json file：

{
"name": "denpa/php-bitcoinrpc",
"type": "library",
"description": "Bitcoin JSON-RPC client based on GuzzleHttp",
"keywords": ["bitcoin","api","jsonrpc","guzzle"],
"homepage": "https://github.com/denpamusic/php-bitcoinrpc",
"license": "MIT",

},

        "Denpa\\Bitcoin\\": "src"
    },
    "classmap" : [
        "tests"
    ]
}

}

I think this problem misleads me.

I'm stuck in it

[denpamusic]

I want to help you, but I think you're using composer wrong as you're not supposed to download php-bitcoinrpc from github and then run composer on it. What you supposed to do, is to create your own project and then install php-bitcoinrpc via composer.

As this is probably your first time dealing with composer package I'll try to explain in detail. For this example I'm going to assume you work in linux environment.

1. First create directory in which your project will reside, lets call it myproject:
   mkdir myproject
2. Then enter your newly created directory:
   cd myproject
3. Run composer require denpa/php-bitcoinrpc "^2.0". You should get message "./composer.json has been created" and package will install with it's dependencies:
4. Then you can create first file(let's call it index.php) of your project and include composer-generated autoloader in it:
   echo "<?php" > index.php && echo "require 'vendor/autoload.php';" >> index.php
5. Now you can write your own code in index.php as described in examples in README file.

[1281152329]

It's very kind of you.I use it for the first time.I will do as you say.hope I am allowed to consult you in the future if I have any problem.

[denpamusic]

Of course you can consult me anytime. I'll try to respond as fast as I can.
Although you'd probably want to use gitter for general support: https://gitter.im/php-bitcoinrpc/Lobby since it's not a issue with php-bitcoinrpc package itself.

[1281152329]

Thank you very much. Everything went well.
Let's get in touch later.

[denpamusic]

Glad to help you! I'll close this issue as resolved then.
