今天,我想更改matplotlib的配置。
搜索matplotlibrc
有两个:
cd到site-packages文件夹中,发现很多软件包的名称中都带有波浪号。
~klearn
是sklearn
,但是还有另一个sklearn
。~atplotlib
也是matplotlib,更改日期为2018-11
~-tplotlib
的更改日期是2019-3.15
matplotlib
的更改日期是2019-3.28
(我最近确实更新了matplotlib)我只是想知道这些波浪符号名称包用于(回滚?),我可以安全地删除它们吗?
答案 0 :(得分:3)
是否有可能通过pip安装了那些特定的软件包?如果是这样,则损坏的目录可能是pip在卸载软件包时(或在卸载软件包以准备更新软件包时)创建的临时目录。
我翻阅了pip源代码,发现this snippet显然仅用于卸载软件包:
class AdjacentTempDirectory(TempDirectory):
"""Helper class that creates a temporary directory adjacent to a real one.
Attributes:
original
The original directory to create a temp directory for.
path
After calling create() or entering, contains the full
path to the temporary directory.
delete
Whether the directory should be deleted when exiting
(when used as a contextmanager)
"""
# The characters that may be used to name the temp directory
# We always prepend a ~ and then rotate through these until
# a usable name is found.
# pkg_resources raises a different error for .dist-info folder
# with leading '-' and invalid metadata
LEADING_CHARS = "-~.=%0123456789"
...
如果这就是这些文件,则可以安全地删除它们。
