我在Ubuntu18.04.1上并行安装了Python 2和3：

#uname -a
Linux mysvr-1 5.4.0-65-generic #73~18.04.1-Ubuntu SMP Tue Jan 19 09:02:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

#python --version
Python 2.7.17

#python3 --version 
Python 3.8.8

我正在尝试使用python3运行一个为python3编写的脚本(它使用了调用pycrypto的simple-crypt )，但是我不能在python3 (pip3)下安装simple-crypt，因为pycrypto安装失败，即使它们都安装在python2下很好。

在安装过程中，我看到以下错误：

#python3 -m pip install simple-crypt

我想可能是这样的：

src/MD2.c:31:10: fatal error: Python.h: No such file or directory

我有以下问题：

我可以下载这个包并从本地tar安装吗？
1. 我可以从现有的Python2 Python2安装到Python3，告诉Python3如何‘使用’当前安装在Python2?
下的软件包(并由Python2)使用。

有什么想法/建议吗？

pip

package

python-2.x

python-3.x

installation

这只是对上文问题1的部分答复：

我可以下载这个包并从本地tar安装吗？

手动安装Python模块：

# Verify the module is not already installed
python3 -m pip list
# As above - Python 2.x
python -m pip list

# Download the module
curl <MODULE_DOWNLOAD_URL> -o <MODULE_FILE_NAME>

# Make sure setuptools are up to date - Python 3.x
python3 -m pip install --upgrade setuptools
# As above - Python 2.x
python -m pip install --upgrade setuptools

# Extract the downloaded gzipped tar file if necessary
tar -xvf <MODULE_FILE_NAME>
# cd into the extracted module folder if created
cd <MODULE_FOLDER>

# Run the included setup.py script to install the module
python3 setup.py install
# Same for Python 2.x
python setup.py install

# Verify the module was successfully installed
python3 -m pip list
# As above - Python 2.x
python -m pip list

如果一切顺利，新模块现在应该出现在已安装/可用模块列表中。

尝试pip安装pipwin，然后pipwin安装pycrypto，但是如果这不起作用，这意味着您可能不得不将您的python版本降到3.3，1.5.2不支持since.this，这是因为pycrypto是在2013年推出的，当时python3.8还没有发布，所以没有支持。
