php 作曲家：找不到命令

Composer: Command Not Found

提问by Brandon Buster

From within the directory holding my composer.phar file, I can't execute any composer commands.

在我的 composer.phar 文件所在的目录中，我无法执行任何 composer 命令。

I can see Composer is running when I execute

当我执行时，我可以看到 Composer 正在运行

php composer.phar 

But any direct composer statements fail.

但是任何直接的作曲家语句都失败了。

Not sure if it matters but Composer was included within a cloned repository.

不确定这是否重要，但 Composer 包含在克隆的存储库中。

I just want to install a single Oauth library, then likely not touch Composer again for several months, so I don't need to run it globally. I'm just confused why I can't run Composer from within this directory.

我只想安装一个 Oauth 库，然后可能几个月内不会再接触 Composer，所以我不需要全局运行它。我只是很困惑为什么我不能从这个目录中运行 Composer。

Your composer.pharcommand lacks the flag for executable, or it is not inside the path.

您的composer.phar命令缺少可执行标志，或者它不在路径内。

The first problem can be fixed with chmod +x composer.phar, the second by calling it as ./composer.phar -v.

第一个问题可以通过 来解决chmod +x composer.phar，第二个问题可以通过调用为 来解决./composer.phar -v。

You have to prefix executables that are not in the path with an explicit reference to the current path in Unix, in order to avoid going into a directory that has an executable file with an innocent name that looks like a regular command, but is not. Just think of a catin the current directory that does not list files, but deletes them.

您必须为不在路径中的可执行文件加上对 Unix 中当前路径的显式引用作为前缀，以避免进入包含可执行文件的目录，该可执行文件的名称看起来像一个普通命令，但实际上不是。想想cat当前目录中的一个没有列出文件，而是删除它们。

The alternative, and better, fix for the second problem would be to put the composer.pharfile into a location that is mentioned in the path

解决第二个问题的另一种更好的方法是将composer.phar文件放入路径中提到的位置

This problem arises when you have composer installed locally. To make it globally executable,run the below command in terminal

当您在本地安装 composer 时会出现此问题。要使其全局可执行，请在终端中运行以下命令

Composer Docs 页面上的安装说明非常重要，否则。

First I did alias setup on bash / zsh profile.

首先，我在 bash / zsh 配置文件上设置了别名。

alias composer="php /usr/local/bin/composer.phar"

Then I moved composer.phar to /usr/local/bin/

然后我将 composer.phar 移动到 /usr/local/bin/

cd /usr/local/bin
mv composer.phar composer

Then made composer executable by running

然后通过运行使作曲家可执行

sudo chmod +x composer
