linux ubuntu pecl: command not found

当您在Linux Ubuntu系统中尝试运行`pecl`命令，但收到"command not found"错误时，这意味着您的系统无法找到名为`pecl`的工具，它通常是PHP的Composer Extension Manager (PECL)的别名。这可能是由于几个原因：

1. **未安装PECL**：`pecl`默认不是Ubuntu的官方组件，需要先安装。打开终端，输入`sudo apt-get install php7.4-pecl`（如果使用的是php7.4，替换为相应版本），然后按提示操作。

2. **PATH环境变量未设置**：检查您的`~/.bashrc`或`~/.zshrc`文件，确认是否已添加了PECL到系统的路径。如果没有，添加`export PATH=/usr/lib/php/$(php-config --prefix)/bin:$PATH`并保存，然后重启终端使其生效。

3. **PHP版本问题**：确保您正在使用的PHP版本与`pecl`对应。例如，如果已经安装了PHP 8，那么应使用`php8.0-dev`而不是`php7.4-pecl`。

4. **更新或手动安装**：如果上述都没有问题，尝试更新系统包列表，然后再次尝试安装：`sudo apt update && sudo apt install php7.4-dev`。

如果以上步骤都试过还是无法解决，可能是PECL源的问题，可以考虑更换国内镜像源或直接从PECL官网下载安装脚本。

pecl: command not found

The "pecl" command not found error typically occurs when the PHP Extension Community Library (PECL) is not installed or not added to your system's PATH. PECL is a repository of PHP extensions that can be installed to enhance the functionality of your PHP installation.

To resolve this issue, you can try the following steps:

1. Verify if PECL is installed by running the command: `pecl version`. If it is not installed, you will need to install it.

2. If you are using a Linux distribution, you can install PECL by running the following command in your terminal:

   sudo apt-get install php-pear

3. After installing PECL, you might need to add the PECL binaries directory to your system's PATH. You can typically find the location of the binaries in the `/usr/bin` or `/usr/local/bin` directory. To add it to your PATH, you can modify your shell configuration file (e.g., `.bashrc`, `.zshrc`) and append the following line:

   export PATH="/usr/bin:$PATH"  # Replace with the actual location of the PECL binaries

4. Save the file, then reload your shell configuration by running `source ~/.bashrc` (or `source ~/.zshrc` if you are using Zsh).

After these steps, you should be able to use the `pecl` command without any issues.
