[英]mypy and distributing a namespace package
I have a set of namespace packages that are meant to run in a python3.6 environment.我有一组要在 python3.6 环境中运行的命名空间包。
They are each set up as follows:它们分别设置如下:
if sys.version_info < (3, 6):
print("Python versions < 3.6 unsupported", file=sys.stderr)
sys.exit(1)
setup(
name="mynamespace.subpackage",
version=VERSION,
packages=[
"mynamespace.subpackage",
],
package_dir={"": "src"},
package_data={
"": [],
},
include_package_data=True,
zip_safe=False,
install_requires=[
"mynamespace.core", # May have explicit dependencies that are not cyclic
],
namespace_packages=["mynamespace"],
...
)
All of the subpackages install just fine side-by-side.所有子包都可以并排安装。
The problem comes when I want to get robust type-checking via mypy
.当我想通过
mypy
健壮的类型检查时,问题就出现了。 mypy
is unable to find the mynamespace.core
subpackage when being run on the source files for mynamespace.subpackage
(for example) which means that I don't get robust typing checking across my sub-package boundaries. mypy
无法找到mynamespace.core
子包被在源文件运行时mynamespace.subpackage
(例如),这意味着我不明白在我的分装的界限强大的打字检查。
This appears to be a known problem: https://github.com/python/mypy/issues/1645这似乎是一个已知问题: https : //github.com/python/mypy/issues/1645
Guido mentions that the workaround is to "add a dummy __init__.py
or __init__.pyi
files", but he doesn't really elaborate and it turns out that this isn't as obvious to me as I had hoped. Guido 提到解决方法是“添加一个虚拟的
__init__.py
或__init__.pyi
文件”,但他并没有详细说明,事实证明这对我来说并不像我希望的那么明显。 Adding those files to the local repo allows mypy to run over the local repo as expected, I can't figure out how to get access to the typing information in a sibling namespace package.将这些文件添加到本地存储库允许 mypy 按预期运行本地存储库,我不知道如何访问同级命名空间包中的输入信息。
My question is: how would I modify mynamespace.core
-- so that when installed, mypy
is able to pick up it's type information in other modules?我的问题是:我将如何修改
mynamespace.core
—— 以便在安装时, mypy
能够在其他模块中获取它的类型信息?
Hopefully you've fixed it by now (or given up!!) but for any fellow dwellers, the answer is to run:希望你现在已经修复了它(或放弃了!!)但是对于任何同胞来说,答案是运行:
mypy --namespace-packages -p mynamespace.subpackage
Note that when you use the -p
arg you cannot specify a directory as well.请注意,当您使用
-p
arg 时,您也不能指定目录。
