我试图在this node module应用程序中修补补丁electron。我想更改if (process.platform == "darwin") {
let refSCapt = screenshot.capture;
console.log("Outside");
screenshot.capture = function(output: string, callback: any) {
console.log("Inside");
// Override output path of a temp .png file
let tempOutput = output.split("/")[-1];
refSCapt(this.screenshotsPath + tempOutput, callback);
};
}
方法输入参数。
到目前为止我的代码看起来像这样:
Outside
问题在于补丁没有反映,并且原始方法被称为好像什么都不会改变。已记录Inside
获取,但永远不会调用import pandas
def build_dataframe(data2):
tuple_list = []
data_dict = {}
for source in sorted(data2.keys()):
tuple_list.extend([(source, target) for target in sorted(data2[source])])
data_dict.update({(source, target): data2[source][target] for target in sorted(data2[source])})
multi_index = pandas.MultiIndex.from_tuples(tuple_list, names=["index1", "index2"])
df = pandas.DataFrame(index=multi_index, columns=[0], data={0: data_dict})
return df
def dataframe_get(df, index2, default_value=0):
return df.loc(axis=0)[:, index2]
def dict_get(input_dict, key, default_value=0):
return {index1: dictionary.get(key, default_value) for index1, dictionary in input_dict.iteritems()}
data = {123: {6544: 44, 23423: 66, 12: 65}, 234: {725: 42, 7245: 62}}
df_data = build_dataframe(data)
print df_data
print dict_get(data, 12, 999)
print dataframe_get(df_data, 12, 999)
。
那我怎么能修补这个模块方法呢?
答案 0 :(得分:4)
那么我怎么能修补这个模块方法?
如果您的代码在其他地方使用之前运行,那么您拥有的功能可以正常工作......但仅。为了实现可靠的修补,我建议https://github.com/ds300/patch-package安装补丁模块。
