我試圖在LiClipse中運行pyLint並使用選項重定向消息到控制檯時出現此錯誤。我在命令提示符下運行該行，沒有任何錯誤。所以問題在於LiClipse沒有正確地重定向輸出。有任何想法嗎 ？

/usr/local/bin/pylint --rcfile=/Users/amansehgal/.rcfile --include-ids=y /Users/amansehgal/Documents/cis519/hw3_skeleton/boostedDT.py 

Answer 1

這通常意味着控制檯env與LiClipse env不同。

要解決該問題，請從LiClipse內部和shell中打印環境變量。

你可以通過創建一個python腳本，例如：

for key, val in sorted(os.environ.items()): 
    print('%s:\n %s' % (key, '\n '.join(sorted(val.split(os.pathsep))))) 

，然後比較，你在這兩種情況下具有的值。

最常見的問題是在PATH，PYTHONPATH，DYLD_LIBRARY_PATH（在Mac上）或LD_LIBRARY_PATH（在Linux上）ENV變量。

您也可以嘗試從啓動命令的同一個shell啓動LiClipse，以便它從shell中繼承env變量。
