Xargs：通过"查找"tests.py manage.py 测试

Question

我尝试在django项目目录中执行以下bash命令。我正在使用django-nose作为测试运行器。

find . -name tests.py -print0 | xargs -0 -Ixxx ./manage.py test xxx --settings=project_name.conf.test.settings

但我收到以下错误（取决于 tests.py 文件的数量）：

OSError: No such file /Users/user/Projects/project_name/{}

同样的呼啸-print0在第一个tests.py停止

完整回溯（命令-print0：

nosetests --verbosity 1 ./project_name/backend/tests.py
./project_name/contrib/auth/tests.py
./project_name/frontend/tests.py
 --failed --stop --nocapture --debug=DEBUG --nologcapture

在这种情况下，使用xargs的正确方法是什么？

以下命令是正确的：

find . -name tests.py -print0 | xargs -0 -Ixxx ./manage.py test xxx --settings=project_name.conf.test.settings

在运行它之前，我刚刚做了rm .noseids。如果您使用错误的参数执行./manage.py test，它总是会导致问题。然后用.noseids编写，然后每次执行。
