1、

 首先按照https://pypi.org/project/ale-python-interface/0.0.1/ 來安裝，直接python3 -m pip

但提示缺少一個頭檔案ale_c_wrapper.h，報錯如下：

1     ale_python_interface/ale_c_wrapper.cpp:1:10: fatal error: ale_c_wrapper.h: No such file or directory
2      #include "ale_c_wrapper.h"
3               ^~~~~~~~~~~~~~~~~
4     compilation terminated.
 
5     error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
6   

不過這個網上有一個blog寫到這個問題，不過他的方法我試了不可以，你們可以試試：https://blog.csdn.net/senjie_wang/article/details/84073823

2、

然後按照https://github.com/bbitmaster/ale_python_interface/wiki/Installation-Instructions，來安裝。

結果在第一大步的最後一小步，make時出錯，報錯如下：

 從這個報錯中，就可以發現，基本就是StellaEnvironmentWrapper::*   什麼什麼沒有定義。

終於找到相關的檔案stella_environment_wrapper.cpp 和 stella_environment_wrapper.hpp

在下載的檔案Arcade-Learning-Environment的./src/environment/目錄下面。

從下面截圖就能發現很奇怪，在make一遍後，相關檔案都被編譯成.o檔案了，卻沒有stella_environment_wrapper.o檔案：

於是開啟這個目錄裡面的module.mk檔案：$ vi module.mk

為什麼只產生三個.o檔案，不生成stella_environment_wrapper.o檔案啊。

於是把它改成：

就是多加了一行，生成對應的stella_environment_wrapper.o檔案。

然後再返回到Arcade-Learning-Environment目錄，然後再執行一遍make。

再執行一遍$ ls，看到當前目錄下有libale.so，就成功了

OK

done.
