环境

mac os 10.14.4
visuals studio code Version 1.33.1 (1.33.1)
.tox/venv/bin/python
python3

背景

休息日得空，所以想着看下horizon代码，但是激活虚拟环境后，用code . 无法打开，虚拟环境是上回装的，中间好像用brew升级过python3。无法打开的报错如下：

dyld: Library not loaded: @executable_path/../.Python
  Referenced from: /Users/robot/code/Openstack/Rep/horizon/.tox/venv/bin/python
  Reason: image not found
/usr/local/bin/code: line 10: ./MacOS/Electron: No such file or directory

解决方法

ls -al .tox/venv/

由于之前的更新这边的软连接已经失效了，我这里执行下链接路径发现报错如下。

/usr/local/Cellar/python/3.7.2_1/Frameworks/Python.framework/Versions/3.7/Python
zsh: correct '/usr/local/Cellar/python/3.7.2_1/Frameworks/Python.framework/Versions/3.7/Python' to '/usr/local/Cellar/python/3.7.2_2/Frameworks/Python.framework/Versions/3.7/Python' [nyae]? n
zsh: no such file or directory: /usr/local/Cellar/python/3.7.2_1/Frameworks/Python.framework/Versions/3.7/Python

现在本地虚拟环境的python路径为/usr/local/Cellar/python/3.7.2_2/Frameworks/Python.framework/Versions/3.7/Python

删除软链接

find .tox/venv/ -type l -delete

重新生成软链接

virtualenv .tox/venv/
