This article will explain in detail the solution that php composer can not download the installation package. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Php composer cannot download the installation package: 1, configure the domestic source globally or configure the current project with the domestic source; 2, use the local source of the current project; 3, configure the agent through the command line, and find the server and the port to find its own.

Several solutions for composer unable to download the installation package

Why am I slow?

In general, the data of the composer installation package (mainly zip files) is downloaded from github.com.

Due to some unknown reasons, the connection speed of foreign websites is very slow. It doesn't even exist.

Being slow is understandable.

Installation failed now

Solution:

1.1 Global configuration of domestic sources

Enter on the command line

Composer config-g repo.packagist composer https://packagist.phpcomposer.com

Done.

If you don't want to use domestic sources,

Composer config-g-- unset repos.packagist

1.2 current project configuration domestic source

The command line goes to the project composer.json sibling directory (usually the project root directory)

Enter on the command line

Composer config repo.packagist composer https://packagist.phpcomposer.com

It is equivalent to directly modifying composer.json and adding it under repositories.

{"type": "composer", "url": "https://asset-packagist.org"}

Modified result

"repositories": [{/ / I am the previous configuration}, {"type": "composer", "url": "https://asset-packagist.org"}]

There are also small partners to install the project composer.json is purple.

"repositories": {"packagist": {"type": "composer", "url": "https://packagist.phpcomposer.com"}}"

Correct according to the rules

"repositories": [{"type": "composer", "url": "https://packagist.phpcomposer.com"}, {" type ":" composer "," url ":" https://asset-packagist.org"}]

No longer want to use domestic sources

Composer config-unset repos.packagist

Or delete the corresponding added repositories.

It is convenient to use domestic sources, but it is not very stable. Some packages just can't be downloaded.

2 the current project uses a local source

1) first put the downloaded installation package data into a folder. This article takes the composerPackages folder under the same level directory of composer.json as an example.

Generally speaking, after the installation fails directly with composer, there will be a prompt indicating that the download of such and such files failed.

Modify composer.json and add it under repositories

{"type": "path", "url": "composerPackages/*", "options": {"symlink": true}}

The modification is as follows

"repositories": [{/ / I am the previous configuration}, {"type": "path", "url": "composerPackages/*", "options": {"symlink": true}}]

3.1 Command line to configure the agent, find the server and the port to find its own

1.

Command line input

Set http_proxy= proxy address: proxy port

For example, the proxy address is local 127.0.0.1 port 10809

Set http_proxy=127.0.0.1:10809

3.2 add user environment variables to configure the agent

3.3 configure the agent when you install composer

After the agent is configured locally, the corresponding agent is automatically selected. After selecting the agent, composer will verify whether the agent is available.
