我知道如何使用 pip 查看已安装的 Python 包,只需使用 pip freeze
.但是有什么方法可以查看使用 pip 安装或更新包的日期和时间?
I know how to see installed Python packages using pip, just use pip freeze
. But is there any way to see the date and time when package is installed or updated with pip?
如果不需要区分更新和安装,可以使用包文件的更改时间.
If it's not necessary to differ between updated and installed, you can use the change time of the package file.
就像 Python 2 一样,带有 pip <10:
Like that for Python 2 with pip < 10:
import pip, os, time
for package in pip.get_installed_distributions():
print "%s: %s" % (package, time.ctime(os.path.getctime(package.location)))
或类似的更新版本(使用 Python 3.7 测试并安装了带有 pkg_resources
的 setuptools 40.8):
or like that for newer versions (tested with Python 3.7 and installed setuptools 40.8 which bring pkg_resources
):
import pkg_resources, os, time
for package in pkg_resources.working_set:
print("%s: %s" % (package, time.ctime(os.path.getctime(package.location))))
在这两种情况下,输出都将类似于 numpy 1.12.1: Tue Feb 12 21:36:37 2019
.
an output will look like numpy 1.12.1: Tue Feb 12 21:36:37 2019
in both cases.
顺便说一句:您可以使用 pip list
而不是使用 pip freeze
,它能够提供更多信息,例如通过 pip list -o代码>.
Btw: Instead of using pip freeze
you can use pip list
which is able to provide some more information, like outdated packages via pip list -o
.
