Question

我的代码：

jarfile = "res/StringUtilsv102.jar"
#project = "5.1"
#apkName = "com.am.fl"  // added to show what ll b strin passed on to the function
def generate_idfile(project,apkName):
    cmd = "java -jar %s listStringIds  %s %s" %(jarfile, project ,apkName)
    arglist = shlex.split(cmd)
    outfile = 'output.txt'
    idfile = "idfile.txt"
    if(os.path.exists(idfile)):
        os.remove(idfile)
    process = subprocess.Popen(arglist, cwd=os.getcwdu())
    process.wait()
    os.rename(outfile, idfile)

O / p抛出错误，因为没有这样的文件或目录。我已经尝试了所有可能的解决方案来清除错误但无助。

Error:
Traceback (most recent call last):

Answer 1

您需要启动java二进制存在的进程：

process = subprocess.Popen(arglist, cwd="/path/to/java/dir")

或使用shell=True允许PATH环境变量为您解析路径。

process = subprocess.Popen(arglist, shell=True)

引发child_exception的原因OSError：[Errno 2]没有这样的文件或目录
