问题描述
我在尝试使用 grep 查找日志中包含多行的消息时遇到以下错误...谁能提供有关如何克服此错误的输入?
I am running into following error while trying to grep for a message consisting of multipe lines in a log...can anyone provide inputs on how to overcome this error?
代码:-
print gerrit_commitmsg
gerritlog = Popen('git','log','--grep','gerrit_commitmsg', stdout=PIPE, stderr=PIPE)
print gerritlog
错误:-
Commit message:-
Build system changes
Build system changes to include packages in the build
Change-Id: I697558f01ae367d2baacdf2c7fcf1a03753edacd
Traceback (most recent call last):
File "gerrits_in_workspace.py", line 87, in <module>
main()
File "gerrits_in_workspace.py", line 77, in main
grep_commitmsg(gerrit_commitmsg)
File "gerrits_in_workspace.py", line 48, in grep_commitmsg
gerritlog = Popen('git','log','--grep','gerrit_commitmsg', stdout=PIPE, stderr=PIPE)
File "/usr/lib/python2.7/subprocess.py", line 629, in __init__
raise TypeError("bufsize must be an integer")
推荐答案
subprocess.Popen 类需要这样的参数列表:
The subprocess.Popen class expects an argument list like this:
Popen(args, bufsize=0, ...)
所以你通过了它:
args=gitbufsize=日志
args=gitbufsize=log
因此错误(bufsize 需要一个整数值).命令向量需要是一个列表，像这样:
Hence the error (bufsize expects an integer value). The command vector needs to be a list, like this:
gerritlog = Popen(['git','log','--grep','gerrit_commitmsg'], stdout=PIPE, stderr=PIPE)
这篇关于对消息进行 grepping 时，bufsize 必须是整数错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持跟版网！
