Conda:列出使用特定程序包的所有环境 [英] Conda: list all environments that use a certain package
问题描述
如何获取使用conda中某个软件包的所有环境的列表?
How can one get a list of all environments that use a certain package in conda?
推荐答案
以下是如何使用Conda Python软件包(在 base 环境中运行)的示例:
Here's an example of how to do it with the Conda Python package (run this in base environment):
import conda.gateways.logging
from conda.core.envs_manager import list_all_known_prefixes
from conda.cli.main_list import list_packages
from conda.common.compat import text_type
# package to search for; this can be a regex
PKG_REGEX = "pymc3"
for prefix in list_all_known_prefixes():
exitcode, output = list_packages(prefix, PKG_REGEX)
# only print envs with results
if exitcode == 0 and len(output) > 3:
print('\n'.join(map(text_type, output)))
此功能自Conda v4.10.0起可用,但由于它依赖于内部方法,因此无法保证继续进行.也许这应该是一个功能请求,例如对于 conda list --any
之类的CLI命令.
This works as of Conda v4.10.0, but there since it relies on internal methods, there's no guarantee going forward. Perhaps this should be a feature request, say for a CLI command like conda list --any
.
这里是使用参数作为程序包名称的版本:
Here is a version that uses arguments for package names:
conda-list-any.py
#!/usr/bin/env conda run -n base --no-capture-output python
## Usage: conda-list-any.py [PACKAGE ...]
## Example: conda-list-any.py numpy pandas
import conda.gateways.logging
from conda.core.envs_manager import list_all_known_prefixes
from conda.cli.main_list import list_packages
from conda.common.compat import text_type
import sys
for pkg in sys.argv[1:]:
print("#"*80)
print("# Checking for package '%s'..." % pkg)
n = 0
for prefix in list_all_known_prefixes():
exitcode, output = list_packages(prefix, pkg)
if exitcode == 0 and len(output) > 3:
n += 1
print("\n" + "\n".join(map(text_type, output)))
print("\n# Found %d environment%s with '%s'." % (n, "" if n == 1 else "s", pkg))
print("#"*80 + "\n")
顶部的shebang应该确保它至少可以在Unix/Linux系统上在 base 中运行.
The shebang at the top should ensure that it will run in base, at least on Unix/Linux systems.
