在Ubuntu上使用Wordpress的新实例，我通过these instructions安装了wp-cli。我试过了downloading the .phar package, chmodding it, etc。我也试过了installing a .deb package。在这两种情况下，我在运行wp plugin update --all --debug时都会遇到相同的错误：

我已经浏览了list of support options，而我仍然无法让wp-cli在AWS Lightsail（又名Bitnami）上正常运行。查看github和wordpress.org forums，我发现很多用户都有上述部分或全部错误。我尝试了所有建议的解决方法：
wp-config.php：将ABSPATH行包装在条件中。wp-config.php：将add_filter()电话移至MU插件。chmod和chown更改。其中一些确实会使各自的错误消失，但wp仍然无法更新插件等。
我是否需要创建PHP调试输出中标识的缺失文件？
我应该不使用AWS Lightsail / Bitnami吗？我真的需要wp-cli，所以我愿意转移到ec2或其他任何地方。

我在那里看到两个不同的问题。
您在$_SERVER['HTTP_HOST']文件中使用wp-config.php，
在运行WP-CLI时未设置。由于WP-CLI是作为一个运行的
命令行工具，一些仅限Web的常量/变量
没有设置。您需要手动设置或提供
条件覆盖。
WordPress本身无法创建解压缩目录 下载的插件存档文件。这可能是由于1.以上（如 WordPress可能正在寻找错误的位置），或者它可能是一个 无关的问题，比如使用不同的用户运行WP-CLI 没有所需的权限。
这两个问题不是由WP-CLI直接引起的，而是由WordPress安装的特定设置引起的。

Bitnami开发者在这里。
您可以尝试以用户daemon身份运行命令吗？
sudo su -s /bin/bash daemon
这是有权在服务器上写入的用户
答案 2 :(得分：2)
谢谢Javier Salmeron！这正是我必须做的，按顺序：
sudo su -s /bin/bash daemon
export PATH=/opt/bitnami/varnish/bin:/opt/bitnami/sqlite/bin:/opt/bitnami/php/bin:/opt/bitnami/mysql/bin:/opt/bitnami/apache2/bin:/opt/bitnami/common/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
cd /home/bitnami/apps/wordpress/htdocs
现在它起作用了，因为以下是真的：
daemon。$PATH能够找到/opt/bitnami/php/bin/php。/home/bitnami/apps/wordpress/htdocs 以下命令成功运行：wp plugin update --all --debug
Debug (bootstrap): No readable global config found (0.058s)
