The process class relies on proc_open, which is not available on your php installation.

由于无法从 dist 下载 yiisoft/yii2-composer (2.0.7),现在尝试从源代码下载,Process 类依赖于 proc_open ,这在PHP安装中不可用
1. Since the yiisoft/yii2-composer (2.0.7) cannot be downloaded from dist, now try to download from the source code, the process class depends on proc_open , which is not available in php installation, as shown in Figure 1

2. Edit Dockerfile, delete proc_open, proc_close in disable_functions

3. The previous proc_open and proc_close were also disabled and can be built normally, because you can download yiisoft/yii2-composer normally from dist (2.0.6), therefore, it will not be downloaded from the source code, and proc_open and proc_close will not be used, as shown in Figure 2
之前 proc_open、proc_close 也是禁用的,可以正常构建,原因在于可以从 dist 正常下载 yiisoft/yii2-composer (2.0.6),因此,不会从源代码下载,也就不会使用到 proc_open、proc_close
Figure 2
4. Rebuild the image, download from the source code, and the build is successful, as shown in Figure 3
重新构建镜像,从源代码下载成功,构建成功
