问题描述
我正在Windows 10 上使用最新版本的conda 4.5.12 上的 anaconda .我正在创建一个非常简单的测试环境，尝试使用 python 3.6.6 安装 lxml .
I am using anaconda on windows 10 with the lastest version of conda 4.5.12. I am creating a very simple test env to try to install lxml with python 3.6.6.
这是我的environment.yml文件:
Here my environment.yml file:
channels:
- defaults
dependencies:
- python=3.6.6
- lxml
然后我使用conda创建一个环境:
Then I create an env using conda:
conda env create -f environment_test.yml -n test26
以下是安装后的软件包列表:
Here the list of packages after the installation:
(test26) C:>conda list
# packages in environment at C:\Program Files\Anaconda3\envs\test26:
#
# Name Version Build Channel
certifi 2018.11.29 py36_0 defaults
libiconv 1.15 h1df5818_7 defaults
libxml2 2.9.8 hadb2253_1 defaults
libxslt 1.1.32 hf6f1972_0 defaults
lxml 4.2.5 py36hef2cd61_0 defaults
pip 18.1 py36_0 defaults
python 3.6.6 hea74fb7_0 defaults
setuptools 40.6.3 py36_0 defaults
vc 14.1 h0510ff6_4 defaults
vs2015_runtime 14.15.26706 h3a45250_0 defaults
wheel 0.32.3 py36_0 defaults
wincertstore 0.2 py36h7fe50ca_0 defaults
zlib 1.2.11 h62dcd97_3 defaults
到目前为止，一切都很好.问题是当我尝试导入包 lxml
So far so good. The issue is when I tried to import the package lxml
(test26) C:>python

具有详细信息(另一个带有env的测试:"test29"):
With verbose info (another test with env: "test29"):
>>> from lxml import etree

如何调试此问题?我会错过依赖吗?
How can I debug this issue ? Do I missed dependency ?
在MacOS上，我没有看到此问题，因此它似乎特定于Windows.Windows上是否有较旧的版本(我尝试过4.1.1和4.2.1)
On MacOS, I don't see the issue so it seems specific to Windows. Is there an older version working on Windows (I tried 4.1.1 and 4.2.1)
使用Windows 10的Anaconda提示创建/激活环境，并使用以下方法激活环境:
The env is created/activated using the Anaconda prompt with Windows 10 and the env is activated with:
conda activate env test29
推荐答案
我们发现的一件事是，某些应用程序正在C:\ Windows \ System32 \下创建一些lib，这是非常糟糕的做法.最后，我执行了以下操作:
One of the thing we discover is that some applications are creating some lib under C:\Windows\System32\ and this is a very bad practice.At the end I did the following:
- 删除C:\ Windows \ System32 \ libxml2.dll
- 删除C:\ Windows \ System32 \ iconv.dll
一切都与此环境兼容，到目前为止，我的Windows应用程序出现了问题.感谢Anaconda团队的Ray.
Everything is working well with this env and so far I got now issue with my Windows applicarions. Thanks to Ray from the Anaconda team for the help.
