在ubuntu环境下make项目python2: not found
时间: 2023-10-08 16:08:44 浏览: 39
在 Ubuntu 环境下,可能是因为你的系统中没有安装 Python 2,或者 Python 2 没有添加到系统的 PATH 环境变量中。你可以尝试使用以下命令安装 Python 2:
```
sudo apt-get update
sudo apt-get install python2.7
```
如果已经安装了 Python 2,你可以尝试将其添加到 PATH 环境变量中。可以通过以下命令将 Python 2 的路径添加到 PATH 环境变量中:
```
export PATH=$PATH:/usr/bin/python2.7
```
如果你在运行 make 命令时仍然遇到问题,请检查你的 Makefile 文件是否正确配置了 Python 2 的路径。

npm ERR! gyp verb `which` failed python2 Error: not found: python2
This error occurs when the system cannot find Python2, which is required by Node.js to build native modules using the node-gyp tool.
To resolve this issue, you need to install Python2 on your system and make sure it is accessible via the PATH environment variable.
Here are the steps you can follow to install Python2:
1. Check if Python2 is already installed on your system by running the following command in your terminal:
```
python2 --version
```
If Python2 is already installed, you should see the version number. If not, you will need to install it.
2. Install Python2 using your system's package manager. For example, on Ubuntu, you can run the following command:
```
sudo apt-get install python2
```
On macOS, you can install Python2 using Homebrew:
```
brew install python@2
```
3. Once Python2 is installed, you need to add it to the PATH environment variable. You can do this by adding the following line to your ~/.bashrc or ~/.bash_profile file:
```
export PATH="/path/to/python2/bin:$PATH"
```
Replace /path/to/python2 with the actual path to the directory where Python2 is installed.
4. Save the file and reload your terminal or run the following command to apply the changes:
```
source ~/.bashrc
```
or
```
source ~/.bash_profile
```
Now try running your original command again and it should work without errors.
Command 'catkin make' not found, but can be installed with!"
根据提供的引用内容,当执行命令`catkin make`时出现了错误提示"Command 'catkin make' not found, but can be installed with!"。这个错误提示表明系统中没有找到`catkin make`命令,但可以通过安装相应的软件包来解决。
以下是解决该问题的步骤:
1. 首先,确保你已经正确安装了ROS(Robot Operating System)。
2. 确认你的环境变量已经正确设置,包括ROS的路径。
3. 如果你已经安装了ROS,但仍然出现该错误,那么可能是因为你没有安装`catkin`软件包。
4. 在终端中运行以下命令来安装`catkin`软件包:
```shell
sudo apt install python-catkin-tools
```
这将安装`catkin`软件包及其相关依赖项。
5. 安装完成后,再次尝试运行`catkin make`命令,应该不再出现错误提示。
请注意,根据你的系统和ROS版本,可能需要使用不同的命令来安装`catkin`软件包。述命令适用于在Ubuntu上使用ROS的情况。
