报错处理（1）激活conda环境后pip库不能安装到已经激活的这个环境

ops 2025/9/2 6:02:22

博主在安装python库的时候，conda activate 环境名，安装的时候conda install 库名不起作用，报错如下：

(py39-qt) PS D:\pycharm_project\learn_pytorch\pythonProject1> conda install pdfplumber
Collecting package metadata (current_repodata.json):done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

总之conda安装无效，只能使用pip安装，并且已经安装成功了。之后运行import 库名的文件又显示没有这个库。

然后在安装时我发现安装的位置是c盘的某个位置，

(py39-qt) PS D:\pycharm_project\learn_pytorch\pythonProject1> pip install pdfplumber
Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple
Requirement already satisfied: pdfplumber in c:\users\lenovo\anaconda3\lib\site-packages (0.11.7)
Requirement already satisfied: pdfminer.six==20250506 in c:\users\lenovo\anaconda3\lib\site-packages (from pdfplumber) (20250506) 
Requirement already satisfied: Pillow>=9.1 in c:\users\lenovo\anaconda3\lib\site-packages (from pdfplumber) (11.3.0)
Requirement already satisfied: pypdfium2>=4.18.0 in c:\users\lenovo\anaconda3\lib\site-packages (from pdfplumber) (4.30.0)        
Requirement already satisfied: charset-normalizer>=2.0.0 in c:\users\lenovo\anaconda3\lib\site-packages (from pdfminer.six==20250506->pdfplumber) (2.0.4)
Requirement already satisfied: cryptography>=36.0.0 in c:\users\lenovo\anaconda3\lib\site-packages (from pdfminer.six==20250506->pdfplumber) (45.0.7)
Requirement already satisfied: cffi>=1.14 in c:\users\lenovo\anaconda3\lib\site-packages (from cryptography>=36.0.0->pdfminer.six==20250506->pdfplumber) (1.15.0)
Requirement already satisfied: pycparser in c:\users\lenovo\anaconda3\lib\site-packages (from cffi>=1.14->crypnovo\anaconda3\lib\site-packages (from cffi>=1.14->cryptography>=36.0.0->pdfminer.six==20250506->pdfplumber) (2.21)

c:\users\lenovo\anaconda3\lib\site-packages 这是不对的，因为我的环境位置是

E:\anaconda3\envs\py39-qt\

这是因为执行conda info --envs可以看到所有环境的位置，我激活的环境名就是py39-qt

(py39-qt) PS D:\pycharm_project\learn_pytorch\pythonProject1> conda info --envs
# conda environments:
#
base                     C:\Users\Lenovo\anaconda3
py38-SDK                 E:\anaconda3\envs\py38-SDK
py39-qt               *  E:\anaconda3\envs\py39-qt

根据人工智能的要求我执行pip uninstall 库名，卸载了这个库

然后指定安装位置执行pip安装：

E:\anaconda3\envs\py39-qt\Scripts\pip.exe install pdfplumber

成功安装并且运行程序了

或者

# 查看当前 PATH 环境变量
$env:PATH# 临时添加 Conda 环境的路径到 PATH 的开头
$env:PATH = "E:\anaconda3\envs\py39-qt\;E:\anaconda3\envs\py39-qt\Scripts;" + $env:PATH# 然后检查 python 和 pip 的位置
python -c "import sys; print(sys.executable)"
python -m pip --version

验证安装：

安装完成后，验证包是否安装到正确位置：

E:\anaconda3\envs\py39-qt\python.exe -c "import pdfplumber; print('Success!'); print(pdfplumber.__file__)"

这应该显示类似 E:\anaconda3\envs\py39-qt\lib\site-packages\pdfplumber\__init__.py 的路径。

还有一件事就是在安装这个库的过程中，它提醒我的conda出现了冲突问题。因为有如下的报错：

AttributeError: module 'lib' has no attribute 'X509_V_FLAG_NOTIFY_POLICY'

人工智能：您的 Conda 环境出现了严重问题，特别是与 OpenSSL 相关的库存在兼容性冲突。错误信息显示 AttributeError: module 'lib' has no attribute 'X509_V_FLAG_NOTIFY_POLICY'，这表明 OpenSSL 库损坏或不兼容。

解决方案

# 首先更新 conda (如果可能)
pip install --upgrade conda# 然后尝试修复 OpenSSL 相关包
pip uninstall pyopenssl cryptography
pip install pyopenssl cryptography#测试是否修复成功，如果这个命令能正常执行并显示环境列表，说明 Conda 已经修复
conda info --envs

然后成功弹出(py39-qt) PS D:\pycharm_project\learn_pytorch\pythonProject1> conda info --envs
# conda environments:
#
base                     C:\Users\Lenovo\anaconda3
py38-SDK                 E:\anaconda3\envs\py38-SDK
py39-qt               *  E:\anaconda3\envs\py39-qt

说明成功解决冲突了
