## pycurl problems
|
|
|
|
Sometimes after installing and importing PyCURL you will see the following error message:
|
|
```
|
|
pycurl: libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other)
|
|
```
|
|
To correct this you need to uninstall PyCURL and reinstall it correctly:
|
|
```
|
|
pip uninstall pycurl
|
|
export PYCURL_SSL_LIBRARY=<ssl_lib>
|
|
pip install pycurl --global-option="--with-<ssl_lib>"
|
|
```
|
|
`<ssl_lib>` can be `openssl` or `nss` depending on your system.
|
|
|
|
