bufsize必須是一個整數錯誤，同時grepping一條消息

Question

我試圖grep的日誌中包含multipe行消息時遇到以下錯誤...任何人都可以提供有關如何克服此錯誤的輸入？

CODE： -

print gerrit_commitmsg 
    gerritlog = Popen('git','log','--grep','gerrit_commitmsg', stdout=PIPE, stderr=PIPE) 
    print gerritlog 

錯誤： -

Commit message:-

Build system changes to include packages in the build

    gerritlog = Popen('git','log','--grep','gerrit_commitmsg', stdout=PIPE, stderr=PIPE)

    raise TypeError("bufsize must be an integer") 

Answer 1

的subprocess.Popen類預期的參數列表如下：

Popen(args, bufsize=0, ...) 

所以你傳遞：

• args = git
• bufsize = log

因此，誤差（bufsize期望的整數值）。命令矢量需要一個列表，像這樣：

gerritlog = Popen(['git','log','--grep','gerrit_commitmsg'], stdout=PIPE, stderr=PIPE)
