将目錄永久添加到PYTHONPATH？

本文翻譯自：Permanently add a directory to PYTHONPATH?

Whenever I use

sys.path.append

, the new directory will be added.

每當我使用

sys.path.append

，都會添加新目錄。

However, once I close python, the list will revert to the previous (default?) values.

但是，一旦我關閉python，清單将恢複為以前的值（預設值）。

How do I permanently add a directory to

PYTHONPATH

?

如何将目錄永久添加到

Instead of manipulating

PYTHONPATH

you can also create a path configuration file .

除了操縱

PYTHONPATH

您還可以建立路徑配置檔案 。

First find out in which directory Python searches for this information:

首先找出Python在哪個目錄中搜尋此資訊：

python -m site --user-site
           

For some reason this doesn't seem to work in Python 2.7.

由于某些原因，這似乎在Python 2.7中不起作用。

There you can use:

在那裡您可以使用：

python -c 'import site; site._script()' --user-site
           

Then create a

.pth

file in that directory containing the path you want to add (create the directory if it doesn't exist).

然後在該目錄中建立一個

.pth

檔案，其中包含要添加的路徑（如果該目錄不存在，則建立該目錄）。

For example:

例如：

# find directory
SITEDIR=$(python -m site --user-site)

# create if it doesn't exist
mkdir -p "$SITEDIR"

# create new .pth file with our path
echo "$HOME/foo/bar" > "$SITEDIR/somelib.pth"

In case anyone is still confused - if you are on a Mac, do the following:

如果仍然有人困惑-如果您使用的是Mac，請執行以下操作：

1. Open up Terminal 打開終端
2. Type

   open .bash_profile

   輸入

   open .bash_profile

3. In the text file that pops up, add this line at the end:

   export PYTHONPATH=$PYTHONPATH:foo/bar

   在彈出的文本檔案中，在末尾添加以下行：

   export PYTHONPATH=$PYTHONPATH:foo/bar

4. Save the file, restart the Terminal, and you're done 儲存檔案，重新啟動終端，然後完成

On linux you can create a symbolic link from your package to a directory of the PYTHONPATH without having to deal with the environment variables.

在Linux上，您可以建立從軟體包到PYTHONPATH目錄的符号連結，而不必處理環境變量。

Something like:

就像是：

ln -s /your/path /usr/lib/pymodules/python2.7/

For me it worked when I changed the

.bash_profile

file.

對我來說，當我更改

.bash_profile

檔案時，它起作用了。

Just changing

.bashrc

file worked only till I restarted the shell.

僅更改

.bashrc

檔案才有效，直到重新啟動外殼程式為止。

For python 2.7 it should look like:

對于python 2.7，它應如下所示：

export PYTHONPATH="$PYTHONPATH:/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python"
           

at the end of the

.bash_profile

file.

在

.bash_profile

檔案的末尾。

This works on Windows

這适用于Windows

1. On Windows, with Python 2.7 go to the Python setup folder. 在Windows上，對于Python 2.7，請轉到Python設定檔案夾。
2. Open Lib/site-packages. 打開庫/站點包。
3. Add an example.pth empty file to this folder. 将example.pth空檔案添加到此檔案夾。
4. Add the required path to the file, one per each line. 将所需的路徑添加到檔案，每行一個。

Then you'll be able to see all modules within those paths from your scripts.

然後，您将能夠從腳本中檢視這些路徑内的所有子產品。
