Install failed via composer

[phucnguyenvn]

Hi buddy,

I got this error when install via composer:

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

[UnexpectedValueException] Could not parse version constraint >=~2: Invalid version string "~2"**

Would you mind sharing your composer.json file? I just tried to install it and managed to install without any problems.

Hi @Edofre I tried to install with a fresh yii2-basic project and I got this error, below is my composer.json file:

My package required yii2 2.0.11. I've loosened the requirements a bit and the following composer.json is working for me on a yii2-app-basic install:

I try install with the above composer.json Can you try with the fresh install of yii2-app-basic and also without any modify the composer.json? I make my module here https://github.com/phucnguyenvn/yii2-evecalendar but the install was failed due to this module.

[Edofre]

With the default yii2-app-basic composer.json it also installs now.

I have yiisoft/yii2-app-advanced installed and get the same error

Could not parse version constraint >=~2: Invalid version string "~2"

I install the newest composer-asset-plugin composer global require "fxp/composer-asset-plugin:dev-master"

and then I can install edofre/yii2-fullcalendar without any error

[Edofre]

What composer version are you using? I'm on Composer version 1.3.2.

Just tried the following commands, and the package installed without any problems..

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-advanced-application
cd yii-advanced-application
composer require edofre/yii2-fullcalendar "V1.0.8"

Waiting for each command to finish of course.

[unst]

My composer version is Composer version 1.3.0 2016-12-24 00:47:03

[Edofre]

@unst And if you update composer? Do you still get the message?

Sorry, I read that wrong, thanks for confirming that the install was working :)

[unst]

Oh, no problem. Thank you
